A team of researchers has been awarded a $738,000 National Science Foundation grant to develop a breathalyzer-type device to detect the onset of hypoglycemia, or low blood sugar episodes, in people with diabetes.
Researchers have developed a wearable liquid-based microfluidic tactile sensor that is small, thin, highly flexible and durable. Simple and cost-effective to produce, this novel device is very suitable for applications such as soft robotics, wearable consumer electronics, smart medical prosthetic devices, as well as real-time healthcare monitoring.
Theoretical physicists have discovered that so-called 'frustrated magnets' can produce skyrmions, tiny magnetic vortices that may be used in memory storage. This discovery opens up a new class of materials for scientists working on 'skyrmionics', which aims to build memory and logic devices based on skyrmions.
Tissue development is guided by gradients of biomolecules that direct the growth, migration, and differentiation of cells. Biomedical engineers are interested in recreating these developmental gradients in adults to aid the growth of new tissue in areas that have sustained damage. Now, researchers are one step closer to this goal thanks to the creation of new 3D-printed scaffolds that enable researchers to release biomolecules into the body with exceptional control.
Researchers have devised a novel type of graphene oxide-based biosensor that could potentially significantly speed up the process of drug development. The outstanding properties of this carbon allotrope help to improve significantly the biosensing sensitivity, which in future may enable the development of new drugs and vaccines against many dangerous diseases including HIV, hepatitis and cancer.
Modern nanofabrication methods have contributed to recent progress in biosensor technology, but challenges remain in developing biosensor assembly platforms that meet important preparation and performance criteria. Now, a team of researchers has developed a new approach that meets at least three of these criteria: system modularity, good signal amplification, and easy purification.
