The sensor will enable doctors to identify tumor markers, whose presence in the body signals the emergence and growth of cancerous tumors.
according to its developers, the sensor can track changes of just a few kilodaltons in the mass of a cantilever in real time.
So the new optical sensor will allow for diagnosing diseases long before they can be detected by any other method,
optomechanical chip.""We've been following the progress made in the development of micro -and nanomechanical biosensors for quite a while now and can say that no one has been able to introduce a simple and scalable technology for parallel monitoring that would be ready to use outside a laboratory.
So our goal was not only to achieve the high sensitivity of the sensor and make it compact,

Without the nanoscale waveguide and the cantilever, the chip simply wouldn't work. Abig cantilever cannot be made to oscillate by freely propagating light,

while charging, different processes are at work in the two identical pieces of carbon pongewhich function as the electrodes in these devices, in contrast to earlier computer simulations.
At its most basic level, a battery is made of two metal electrodes (an anode and a cathode) with some sort of solution between them (electrolyte.
instead, positive and negative electrolyte ions simply tickto the surfaces of the electrodes when the supercapacitor is being charged.
we fill the carbon electrode with tiny holes, like a carbon sponge, said Griffin. ut it hard to know what the ions are doing inside the holes within the electrode we don know exactly what happens
when they interact with the surface. In the new study, the researchers used NMR to look inside functioning supercapacitor devices to see how they charge and store energy.
the two electrodes are different materials, so different processes are said at work Griffin. n a supercapacitor,
the two electrodes are made of the same porous carbon sponge, so you think the same process would take place at both
What the experiments showed is that the two electrodes behave differently. In the negative electrode, there is the expected tickingprocess
and the positive ions are attracted to the surface as the supercapacitor charges. But in the positive electrode, an ion xchangehappens,
as negative ions are attracted to the surface, while at the same time, positive ions are repelled away from the surface.
Additionally, the EQCM was used to detect tiny changes in the weight of the electrode as ions enter and leave.
This enabled the researchers to show that solvent molecules also accompany the ions into the electrode as it charges. e can now accurately count the number of ions involved in the charge storage process
said Griffin. n the future we can look at how changing the size of the holes in the electrode
#MEMS Innovations Enable Commercialization of Implantable Microchips for Drug-Delivery An implantable, microchip-based device may soon replace the injections
and pills now needed to treat chronic diseases: Earlier this month, MIT spinout Microchips Biotech partnered with a pharmaceutical giant to commercialize its wirelessly controlled, implantable,
microchip-based devices that store and release drugs inside the body over many years. Invented by Microchips Biotech cofounders Michael Cima, the David H. Koch Professor of Engineering,
and Robert Langer, the David H. Koch Institute Professor, the microchips consist of hundreds of pinhead-sized reservoirs,
each capped with a metal membrane, that store tiny doses of therapeutics or chemicals. An electric current delivered by the device removes the membrane,
releasing a single dose. The device can be programmed wirelessly to release individual doses for up to 16 years to treat
and osteoporosis. Now Microchips Biotech will begin co-developing microchips with Teva Pharmaceutical, the world largest producer of generic drugs,
Apart from providing convenience, Microchips Biotech says these microchips could also improve medication-prescription adherence a surprisingly costly issue in the United states. A 2012 report published in the Annals of Internal medicine estimated that Americans who don stick to prescriptions rack up $100 billion
Microchips Biotech will continue work on its flagship product, a birth-control microchip, backed by the Bill and Melinda Gates Foundation,
Cima, who now serves on the Microchips Biotech board of directors with Langer, sees this hormone-releasing microchip as one of the first implantable rtificial organsbecause it acts as a gland. lot of the therapies are trying to chemically trick the endocrine systems Cima says. e are doing that with this artificial organ we created.
Wild ideas Inspiration for the microchips came in the late 1990s, when Langer watched a documentary on mass-producing microchips. thought to myself,
ouldn this be a great way to make a drug-delivery system??Langer says. He brought this idea to Cima,
a chip-making expert who was taken aback by its novelty. ut being out-of-this-world is not something that needs to stop anybody at MIT,
Cima adds. n fact, that should be the criterion. So in 1999, Langer, Cima, and then-graduate student John Santini Phd 9 co-founded Microchips,
and invented a prototype for their microchip that was described in a paper published that year in Nature.
This entrepreneurial collaboration was the first of many for Cima and Langer over the next decade.
For years, the technology underwent rigorous research and development at Microchips Biotech. But in 2011, Langer and Cima,
and researchers from Microchips, conducted the microchipsfirst human trials to treat osteoporosis this time with wireless capabilities.
In that study, published in a 2012 issue of Science Translational Medicine, microchips were implanted into seven elderly women,
Results indicated that the chips delivered doses comparable to injections and did so more consistently with no adverse side effects.
That study, combined with ongoing efforts in contraceptive-delivery microchips, led Cima to believe the microchips could someday,
essentially, be considered the first artificial glands that could regulate potent hormones inside the body. This may sound like a wild idea but Cima doesn think so.
The chip ends an endocrine or chemical signal instead of an electrical signal. MEMS innovations Microchips Biotech made several innovations in the microelectromechanical systems (MEMS) manufacturing process to ensure the microchips could be commercialized.
A major innovation was enabling final assembly of the microchips at room temperature with hermetic seals. Any intense heat during final assembly, with hermetic sealing, could destroy the drugs already loaded into the reservoirs
which meant common methods of welding and soldering were off-limits. To do so, Microchips Biotech modified a cold-welding ongue and grooveprocess.
This meant depositing a soft, gold alloy in patterns on the top of the chip to create tongues, and grooves on the base.
By pressing the top and base pieces together, the tongues fit into the grooves, and plastically deforms to weld the metal together. ach one of these reservoirs,
The company has also found ways to integrate electronics into the microchips to shrink down the device.
the company could refine the microchips to be even smaller, yet carry the same volume of drugs. his means making the drugs take up more volume than the electrical and other components,
Keysight's electronic measurement instruments, systems software and services are used in the design, development, manufacture, installation, deployment and operation of electronic equipment.
