Researchers have designed a device that delivers two medications that help stop HIV transmission.
Researchers have successfully used graphene -- one of the strongest, thinnest known materials -- to detect the SARS-CoV-2 virus in laboratory experiments.
Commonplace pharmaceuticals, such as ibuprofen, can carry with them an inherent flaw in their atomic structure, which pairs the active, beneficial ingredient with a potentially ineffective -- or even toxic -- counterpart. New research could hold the key to more easily isolating the good while removing the unwanted.
When someone bumps their elbow against a wall, they not only feel pain but also might experience bruising. Robots and prosthetic limbs don't have these warning signs, which could lead to further injury. Now, researchers reporting in ACS Applied Materials & Interfaces have developed an artificial skin that senses force through ionic signals and also changes color from yellow to a bruise-like purple, providing a visual cue that damage has occurred.
An international team including researchers from The University of Tokyo Institute of Industrial Science has developed spherical colloidal particles for the visualization of rotational dynamics. The two-color fluorescent particles have an off-center core that allows tracking of dense suspensions using microscopy. The researchers observed coupling between the rotation of charged particles, correlation between local crystallinity and rotational diffusivity, and "slip-stick" friction between particles. The findings will enhance the understanding of biological systems and industrial processes.
European scientists propose a personalized protocol for optimizing stimulation of optic nerve fibers, for the blind, which takes into account feedback from the viewer's brain. The protocol has been tested on artificial neural networks known to simulate the physiology of the entire visual system, from the eye to the visual cortex. The stimulation protocol will be tested in clinical trials with partners in Rome.
Nanoengineers at the University of California San Diego have developed immune cell-mimicking nanoparticles that target inflammation in the lungs and deliver drugs directly where they're needed. As a proof of concept, the researchers filled the nanoparticles with the drug dexamethasone and administered them to mice with inflamed lung tissue. Inflammation was completely treated in mice given the nanoparticles, at a drug concentration where standard delivery methods did not have any efficacy.
Although stimulated-emission depletion (STED) microscopy was a true breakthrough for observing the morphology of live neurons at higher resolution, there is still room for improvement. In a recent study published in Neurophotonics, a team of scientists led by Dr. U. Valentin Nägerl from Université de Bordeaux developed a simple yet effective calibration method that allows for more precise STED imaging at higher tissue depths.
A team of scientists at Nanyang Technological University, Singapore (NTU Singapore) has developed millimeter-sized robots that can be controlled using magnetic fields to perform highly maneuverable and dexterous manipulations. This could pave the way to possible future applications in biomedicine and manufacturing.
POSTECH-Dong-A University College of Medicine joint research team presents an innovative eye surface reconstruction method using the photocrosslinked mussel adhesive protein.
