Researchers have integrated silver nanoparticles into the thin plasma polymer coating, which is up to just 100 nanometers thick.
with two plasma polymer layers surrounding a center layer of silver. Within this structure a biocide reservoir is formed
This allows the silver ions to penetrate the outermost plasma polymer layer over a set period of time deemed necessary to properly integrate the implant.

#New method for modifying natural polymers could help bring lifesaving medications to market In drug-delivery research,
a natural polymer often used for drug delivery. According to Kevin Edgar, a professor of sustainable biomaterials and Meng doctoral adviser, the new method an get drugs to market,
Suspending the drug in a polymer matrix can help. Polymers are long chains of repeating units.
Many familiar materials are polymers including proteins, DNA, and cellulose, a sugar-based polymer which gives plant cell walls their structure.
Dispersing a drug in a polymer matrix protects it and suppresses the formation of insoluble crystals.
The polymer eventually swells and releases the drug, allowing it to be absorbed into the bloodstream.
Because medications have broadly diverse chemical structures, properties, and dosing and delivery requirements, finding the right polymer matrix to work well with most drugs involves making
and testing many different options. Meng chemistry offers a new way to make a wide variety of polymer matrices using cellulose as a starting material.
Cellulose is an attractive material for drug delivery because it nontoxic breaks down into components that are already present in the body,
is water-permeable, and can survive the stomach acidic environment. Unlike many synthetic polymers, which are made often from petrochemicals,
cellulose is derived from wood, a renewable resource supporting the mission of the College of Natural resources
renewable starting material to develop a wide variety of polymers specifically tuned to carry many different pharmaceutical targets.
The spectrum of different polymers available is like arvesting apples this year, peaches next year,
and even polymer fibers stretch typically only 20-25 percent, Park noted. That is a limiting factor in a device such as a hand

The flexible, carbon nanotubeaced polymer detects pressure and translates the sensation into pulses of electricity that can be interpreted by the mammalian nervous system,
They then seeped a polymer between the silicon nanowire pillars. After the plastic support solidified, they etched away the silicon backing, leaving bull-eye patterned black silicon embedded in supple plastic.
The dark red polymer material is made using limonene, a compound found in orange peels, and sulphur. It turns yellow
The synthetic coatings are called often polymer brushes because of their bristlelike appearance when attached to the particle surface.
To create the biological equivalent of a polymer brush the researchers turned to neurofilaments pipe cleaner-shaped proteins found in nerve cells.
By acting as tiny cylindrical polymer brushes neurofilaments collectively assemble into a structural network that helps keep one end of the nerve cell propped open
and turned it into a polymer brush by cloning a portion of a gene that encodes one of the neurofilament bristles re-engineering it such that we could attach the resulting protein to surfaces in a precise and oriented way
The DNASE an enzyme that would normally cut up the DNA cocoon is coated in a thin polymer that traps the DNASE like a sword in a sheath.
Once inside the cancer cell the cell acidic environment destroys the polymer sheath containing the DNASE.
A typical lithium-ion battery consists of two tightly packed electrodes--a carbon anode and a lithium metal-oxide cathode--with an ultrathin polymer separator in between.
and his colleagues applied a nanolayer of copper onto one side of a polymer separator creating a novel third electrode halfway between the anode and the cathode.
The copper coating on the polymer separator is only 50 nanometers thick about 500 times thinner than the separator itself said Wu a postdoctoral fellow in the Cui group.
The coated separator is quite flexible and porous like a conventional polymer separator so it has negligible effect on the flow of lithium ions between the cathode and the anode.
and abetted by gelatinous sticky polymers produced by seaweed reports a research team headed by a UC Davis veterinary infectious-disease expert.
Using the parasite Toxoplasma gondii as a model they showed how these sticky polymers increase the chance that disease-causing organisms would be picked up by marine snails
Findings from the new study will be published Oct 8 in the journal Proceedings of the Royal Society B. Discovering the role that these invisible polymers play in disease transmission in the ocean is a tremendous step forward in helping us better understand
In laboratory tests the researchers discovered that the gelatinous polymers excreted by seaweed act in two ways to provide an environment conducive to transmission of infectious diseases.
First the polymers act like glue binding together waterborne organic material into larger particles in
Secondly the polymers help to form sticky biofilms which can trap the T. gondii egg cells and coat kelp on which marine snails graze.
#New Technique Increases Nanofiber Production Rate Fourfold Nanofibers polymer filaments only a couple of hundred nanometers in diameter have a huge range of potential applications, from solar cells
In the first, a polymer solution is pumped through a small nozzle, and then a strong electric field stretches it out.
The cones are dipped in a polymer solution, and the electric field causes the solution to travel to the top of the cones,
and a dissolved polymer. When an electrode is mounted opposite the sawteeth and a voltage applied between them,
the water-ethanol mixture streams upward, dragging chains of polymer with it. The water and ethanol quickly dissolve, leaving a tangle of polymer filaments opposite each emitter, on the electrode.
The researchers were able to pack 225 emitters, several millimeters long, on a square chip about 35 millimeters on a side.
The two components that make the UCLA-developed system work are a polymer donor and a nanoscale fullerene acceptor.
The polymer donor absorbs sunlight and passes electrons to the fullerene acceptor; the process generates electrical energy.
The plastic materials, called organic photovoltaics, are organized typically like a plate of cooked pasta a disorganized mass of long, skinny polymer paghettiwith random fullerene eatballs.
because the electrons sometimes hop back to the polymer spaghetti and are lost. The UCLA technology arranges the elements more neatly like small bundles of uncooked spaghetti with precisely placed meatballs.
The fullerenes inside the structure take electrons from the polymers and toss them to the outside fullerene
which can effectively keep the electrons away from the polymer for weeks. hen the charges never come back together,

which was to use a polymer to seal up a wound very quickly. In the beginning I wasn expecting that the polymer itself would be able to quickly stop bleeds.
We realized that if we put it onto a wound something really remarkable would happenwhich is that it would actually change shape,
and the individual polymer chains to start separating. At this point instead of allowing the material to completely dissolve,
While polymer coatings have been used to achieve more or less this same effect, the polymers degrade rapidly. Even worse, the polymer coatings are sometimes so thick that they actually pose a bigger problem to the heat transfer than the films they are supposed to be combating.
After testing the material in an environment of pure water vapor at 100 degrees Celsius the researcher found that the graphene coating offered a fourfold improvement in heat transfer compared to bare metal.
The MIT researchers have calculated also that these numbers could be improved to a five to seven times improvement by optimizing temperature differences in the system.
a polymer coating solution started to degrade in the environment within three hours and completely failed within 12.
First they use this method to create the desired structure a lattice out of a polymer.
The polymer lattice is coated then with a ceramic such as alumina. Oxygen plasma etches out the polymer leaving behind a lattice of hollow ceramic tubes.
