Scientists at Brookhaven National Laboratory have created “resists”—materials that are used as templates for transferring circuit patterns into device-useful substrates such as silicon – that combine the organic polymer poly(methyl methacrylate), or PMMA, with inorganic aluminum oxide. These “hybrid” organic-inorganic resists enable the patterning of high-resolution silicon nanostructures with a high aspect ratio.
Researchers from Northwestern University have developed a novel way to track how nanoparticles interact with cancer cells and whether they reach their targets. The team’s work shows that if a nanoparticle targets cancer cells, it undergoes more rotational and translational movement compared to nanoparticles that cannot target cancer cells effectively.

Researchers have shown that multilayer graphene can provide a two-fold defense against mosquito bites. The ultra-thin yet strong material acts as a barrier that mosquitoes are unable to bite through. At the same time, experiments showed that graphene also blocks chemical signals mosquitoes use to sense that a blood meal is near, blunting their urge to bite in the first place.

Researchers have revealed previously unknown factors that contribute to the hardening of arteries and plaque growth, which cause heart disease. Their insight is the basis for a promising therapeutic approach to halt and potentially reverse plaque buildup and the progression of disease, the researchers said.

Researchers from Carnegie Mellon University and Nanyang Technological University in Singapore have developed a new microfabricated sensor array that performs 3D electrophysiology of cellular organoids. Their work demonstrates that the device can be designed to wrap around small organoids and measure voltage changes across the surface of the organoids without leading to significant loss of viability of the cells.

Human pathogens have molecular fingerprints that are difficult to distinguish. To better detect these pathogens, sensors in diagnostic tools need to manipulate light on a nanoscale. To manufacture these light-manipulation devices without damaging the sensors, Purdue University engineers have integrated light-manipulation devices onto peelable films that can stick to any surface.
