Bionanomotors, like myosins that move along actin networks in cells, are responsible for motion in all life forms. So the development of artificial nanomotors could make robots more effective and versatile teammates for soldiers in combat. This article describes the work of researchers from the Army Research Laboratory on identifying a design that would allow an artificial nanomotor to take advantage of Brownian motion, the property of particles to move because they are warm.

A team of researchers has found a new way to produce a polymer material called PBO, a product known commercially as Zylon that's used in bulletproof vests and other high-performance fabrics. The new approach could be useful in making PBO products that resist degradation, a problem that has plagued PBO-based materials in the past.

When periodic arrays of metallic nanostructures are illuminated with light, each of the nanoparticles produces a strong response, which, in turn, results in enormous collective behaviors if all of the particles can interact. Scientists at The University of New Mexico have found that decreasing the density of nanoparticles in the array produces field enhancements that are not only larger, but extend farther away from the array.

Research led by University of Texas at Dallas physicists has altered the understanding of the fundamental properties of perovskite crystals, a class of materials with great potential as solar cells and light emitters. In particular, the study presents evidence questioning existing models of the behavior of perovskites on the quantum level.

Rice University scientists have transformed their laser-induced graphene into self-sterilizing filters that grab pathogens out of the air and kill them with small pulses of electricity. The flexible filter may be of special interest to hospitals.

Researchers from Lawrence Livermore National Laboratory and The Chinese University of Hong Kong have developed a nanoscale 3-D printing technique that can fabricate tiny structures 1000 times faster than conventional two-photon lithography techniques, without sacrificing resolution.

A variety of two-dimensional materials quickly degrade when exposed to oxygen and water vapor, and the protective coatings developed thus far are expensive and toxic and cannot be taken off. Now, a team of researchers at the Massachusetts Institute of Technology and elsewhere has developed an ultrathin coating that is inexpensive, simple to apply, and can be removed by applying certain acids.

Researchers at Arizona State University are using a nanomaterial-welding method to make closing wounds and surgical incisions safer.

Researchers at Stanford University have developed nanoparticles that can be used to light up and image tumors located well below the surface of the skin. The nanoparticles should be useful for not only diagnosing and monitoring tumor progression but also for predicting how individual patients will respond to a given immunotherapy.

Electrical engineers at Duke University have devised a fully print-in-place technique for electronics that uses carbon nanotubes and silver nanowires and is gentle enough to work on delicate surfaces, including paper and human skin. The advance could enable high-adhesion, embedded electronic tattoos and bandages tricked out with patient-specific biosensors.
