The biomedical use of a food additive a material widely used in the food industry for its gelling thickening and stabilizing properties as a medium for a drug-delivery system is a novel idea

The new method spins the drug into silklike fibers that quickly dissolve when in contact with moisture, releasing higher doses of the drug than possible with other topical materials such as gels or creams

showing that the fiber materials can hold 10 times the concentration of medicine as anti-HIV gels currently under development.

Ball says. e have achieved higher drug loading in our material such that you wouldn need to insert a large amount of these fibers to deliver enough of the drug to be helpful.

SPINNING THE FABRIC The team created the soft fibers using a process called electrospinning. They first dissolved a polymer

so the researchers looked at different ingredients for the fiber that would allow for the highest concentration of drug with the fastest-possible release in the body.

Because the electrically spun fibers have a large surface area, researchers were able to create samples in

By adjusting the ingredients in the fibers, researchers were able to dissolve the drug in about six minutes,

no matter how much drug mass was in the fiber. The research team says the soft, dissolving fibers could be rolled into a cardboard tampon applicator for insertion or built into the shape of a vaginal ring,

similar to those used for contraception. The material can accommodate different anti-HIV drugs and the team is testing several others for effectiveness.

#This sticky process builds collagen fibers Rice university rightoriginal Studyposted by Mike Williams-Rice on October 28 2014new research offers a detailed look at how synthetic collagen fibers self-assemble via their sticky ends.

or as scaffolding in regenerative medicine Two papers in the Journal of the American Chemical Society the first published in May and the second this month show precisely how mimetic peptides developed at Rice may be aligned to form helices with sticky ends that allow them to aggregate into fibers

The experimental system that the researchers used consists of two tiny directly coupled silica microtoroid (doughnut-shaped) resonators each coupled to a different fiber-taper coupler that aids in guiding light from a laser diode to photodetectors;

the fiber is tapered in the middle so that light can between the fibers and the resonators. Yang says the concept will work in any coupled physical system.

#How to make carbon thread without clumps Made into fibers single-walled carbon nanotubesâ line up like a fistful of raw spaghetti noodles thanks to a new process.

The tricky bit according to Rice university chemist Angel Martã is keeping the densely packed nanotubes apart before they re drawn together into a fiber.

Earlier research at Rice by chemist and chemical engineer Matteo Pasquali a coauthor of the new paper used an acid dissolution process to keep the nanotubes separated until they could be spun into fibers.

The tubes are forced ultimately together into fibers when they are extruded through the tip of a needle.

and it worked perfectlymartã says. The hair-width fibers can be woven into thicker cables and the team is investigating ways to improve their electrical properties through doping the nanotubes with iodide. he research is basically analogous to

what Matteo doesmartã says. e used his tools but gave the process a spin with a different preparation so now we re the first to make neat fibers of pure carbon nanotube electrolytes.

That s very cool. asquali says that the spinning system worked with little need for adaptation

#Stretchy, bendy, stronger-than-ever graphene fiber Researchers have created a simple and scalable method of making strong,

The fibers were modified by adding peptides that can capture select nonliving materials. In this case, the researchers chose peptides that could capture gold nanoparticles and quantum dots.

The fiber muscles can lift 100 times as much as human muscles of the same length

or even to make clothing with fibers that expand or contract to keep the wearer cool or warm.

The twisted fiber creates an artificial muscle that can drive a heavy rotor at a speed of more than 10000 revolutions per minute.

when they twisted the fiber even more it produced coiling as happens when you over-twist a rubber band.

The fiber muscles could be used to power the muscles in androids or exoskeletons the researchers said.

In the case of robotic muscles electrical energy not temperature change would drive the contraction of fibers.

The coiled fibers would simply expand when the air temperature warms to let the clothing breathe.

By contrast the fiber muscles are inexpensive to make and easy to commercialize Baughman said.

#MIT's multifunctional fiber implant could revolutionize neural prosthetics Today cutting edge neural implants can passively read brain activity,

so what new tricks do these fibers bring to the table? Flexible: these fiber based neural implants are much more flexible than the current industry standard, multielectrode arrays and hooked eedlestyle stimulators.

The brain itself is composed of some of the softest tissue in the body, so harder implants that don bend with their surrounding biological environment can easily shift

or chemical, they are so small that several fibers can be bundled together in a customized cable designed for the area it is designed to interface with.

The most exciting thing about these new fibers is undoubtedly the ability to bundle together different functionalities in the same implant,

Scientists at MIT Bioelectronics group not as interested in creating applications for these new multifunctional fibers as they are in perfecting the technology,

The material is produced commonly in reels of very thin straight fiber. To transform the fiber into coils Holschuh borrowed a technique from another MIT group that previously used coiled nickel-titanium to engineer a heat-activated robotic worm.

Shape-memory alloys like nickel-titanium can essentially be trained to return to an original shape in response to a certain temperature.

To train the material Holschuh first wound raw SMA fiber into extremely tight millimeter-diameter coils then heated the coils to 450 degrees Celsius to set them into an original or trained shape.

However at a certain trigger temperature (in this case as low as 60 C) the fiber will begin to spring back to its trained tightly coiled state.

To break down those emulsions crews use de-emulsifiers which can themselves be environmentally damaging. In the 2010 Deepwater horizon oil spill in the Gulf of mexico for example large amounts of dispersants and de-emulsifiers were dumped into the sea.

After a while the oil just disappeared Varanasi says but people know it s hidden in the water in these fine emulsions.

because it naturally produces biofilms that contain so-called curli fibers amyloid proteins that help E coli attach to surfaces.

Each curli fiber is made from a repeating chain of identical protein subunits called Csga which can be modified by adding protein fragments called peptides.

By programming cells to produce different types of curli fibers under certain conditions the researchers were able to control the biofilms properties

This puts control of curli fiber production in the hands of the researchers who can adjust the amount of AHL in the cells environment.

which forms curli fibers that coalesce into a biofilm coating the surface where the bacteria are growing.

If both are present the film will contain a mix of tagged and untagged fibers.

To add quantum dots to the curli fibers the researchers engineered cells that produce curli fibers

along with the bacteria that produce histidine-tagged fibers resulting in a material that contains both quantum dots and gold nanoparticles.

#New fibers can deliver many simultaneous stimuli The human brain complexity makes it extremely challenging to study not only because of its sheer size,

By producing complex multimodal fibers that could be less than the width of a hair, they have created a system that could deliver optical signals and drugs directly into the brain,

In addition to transmitting different kinds of signals, the new fibers are made of polymers that closely resemble the characteristics of neural tissues,

To do that, her team made use of novel fiber-fabrication technology pioneered by MIT professor of materials science

Flexible fiber-based probes The result, Anikeeva explains, is the fabrication of polymer fibers hat are soft and flexible

and look more like natural nerves. Devices currently used for neural recording and stimulation, she says,

called a preform, of the desired arrangement of channels within the fiber: optical waveguides to carry light, hollow tubes to carry drugs,

and drawn into a thin fiber, while retaining the exact arrangement of features within them.

A single draw of the fiber reduces the cross-section of the material 200-fold, and the process can be repeated,

making the fibers thinner each time and approaching nanometer scale. During this process, Anikeeva says, eatures that used to be inches across are now microns.

Combining the different channels in a single fiber she adds, could enable precision mapping of neural activity,

While a single preform a few inches long can produce hundreds of feet of fiber, the materials must be selected carefully so they all soften at the same temperature.

The fibers could ultimately be used for precision mapping of the responses of different regions of the brain or spinal cord,

so stabilizers such as polyvinyl alcohol are added. Unfortunately, these stabilizers tend to shield the surface of the palladium particles,

which reduces their effectiveness as a catalyst. By introducing additional treatments, Yingnan Zhao has managed to fully expose the catalytic surface once again

A key ingredient in green tea, epigallocatechin gallate (EGCG), is an antioxidant which is known to have therapeutic applications in the treatment of many disorders including cancer.

A photonic crystal fiber was used to generate (quasi-white light) supercontinuum to probe the spectral response of select regions within the array.

Further the developed process is based on the continuous and mass-produced process of carbon fiber making it much easier for full-scale commercialization.

since this process is based on the continuous and mass-produced process of carbon fiber. Explore further:

To synthesize the carbon fibers, the chemists first prepare a porous, tubular silica template, starting from commercially available,

but nonporous fibers. This template is filled then with a special mixture of carbon, silicon dioxide and surfactants,

and the fibers themselves are correspondingly more stable.""Nanostructured materials have great potential for the efficient conversion

much better than other carbon fibers,"said Mauricio Terrones, professor of physics, chemistry and materials science and engineering, Penn State."

"We believe that pockets of air inside the fiber keep it from being brittle.""This method opens up multiple possibilities for useful products, according to Terrones and colleagues.

special fibers could also be developed with nanostructures to conduct and store energy. More immediate applications could be seen in the design

That could lead to specially treated clothing fibers being able to hold enough power for big tasks.

#Flexible supercapacitor raises bar for volumetric energy density Scientists have taken a large step toward making a fiber-like energy storage device that can be woven into clothing

The fiber-structured hybrid materials offer huge accessible surface areas and are highly conductive. The researchers have developed a way to continuously produce the flexible fiber enabling them to scale up production for a variety of uses.

To date they've made 50-meter long fibers and see no limits on length. They envision the fiber supercapacitor could be woven into clothing to power medical devices for people at home or communications devices for soldiers in the field.

Or they say the fiber could be a space-saving power source and serve as energy-carrying wires in medical implants.

Yuan Chen a professor of chemical engineering at NTU led the new study working with Dingshan Yu Kunli Goh Hong Wang Li Wei and Wenchao Jiang at NTU;

Qiang Zhang at Tsinghua; and Liming Dai at Case Western Reserve. The scientists report their research in Nature Nanotechnology.

To improve the energy density by volume the researchers designed a hybrid fiber. A solution containing acid-oxidized single-wall nanotubes graphene oxide and ethylenediamine

Sheets of graphene one to a few atoms thick and aligned single-walled carbon nanotubes self-assemble into an interconnected prorous network that run the length of the fiber.

The process using multiple capillary columns will enable the engineers to make fibers continuously and maintain consistent quality Chen said.

The researchers have made fibers as long as 50 meters and found they remain flexible with high capacity of 300 Farad per cubic centimeter.

In testing they found that three pairs of fibers arranged in series tripled the voltage

Three pairs of fibers in parallel tripled the output current and tripled the charging/discharging time compared to a single fiber operated at the same current density.

When they integrate multiple pairs of fibers between two electrodes the ability to store electricity called capacitance increased linearly according to the number of fibers used.

Using a polyvinyl alcohol/phosphoric acid gel as an electrolyte a solid-state micro-supercapacitor made from a pair of fibers offered a volumetric density of 6. 3 microwatt hours per cubic millimeter

which is comparable to that of a 4-volt-500-microampere-hour thin film lithium battery. The fiber supercapacitor demonstrated ultrahigh energy density value

while maintaining the high power density and cycle stability. We have tested the fiber device for 10000 charge/discharge cycles

and the device retains about 93 percent of its original performance Yu said while conventional rechargeable batteries have a lifetime of less than 1000 cycles.

The fiber supercapacitor continues to work without performance loss even after bending hundreds of times Yu said.

and structurally consistent over their length the fibers can also be woven into a crossing pattern into clothing for wearable devices in smart textiles.

They plan to scale up the technology for low-cost mass production of the fibers aimed at commercializing high-performance micro-supercapacitors.

In addition The team is interested also in testing these fibers for multifunctional applications including batteries solar cells biofuel cells

made of resin reinforced by carbon epoxy fiber.""So that little thing that's so light,"he says,

The approach starts with testing fibers and matrix materials; then the tests get, as the handbook states,"increasingly more complicated,"until reaching the level of structural subcomponent (or higher).

"The resin that's between the fibers starts developing little micro-cracks,"says Michopoulos, which can cause the resin to separate from the fibers or the fibers to break."

"A continuous accumulation of micro-cracking (that leads to a softening of the material) can be used as a metric for material degradation assessment."
