Easy way to spin nanofibers, inspired by silkworms (video)
The way that silkworms wind their cocoons is now helping scientists more easily make new biomedical materials. Researchers in ACS’ Nano Letters have mimicked the seemingly simple head bobbing of silkworms to create more consistent micro- and nanofibers with less equipment than other approaches.
AI-driven dynamic face mask adapts to exercise, pollution levels
Researchers reporting in ACS Nano have developed a dynamic respirator that modulates its pore size in response to changing conditions, such as exercise or air pollution levels, allowing the wearer to breathe easier when the highest levels of filtration are not required.
Nanofiber Face Masks Improve Filtration Efficiency, Need Replacing More Often
Innovations to improve mask efficacy, with increasing focus on nanofiber manufacturing, have resulted in higher filtration efficiency, greater comfort, and easier breathing capacity. However, the effects of microwater droplets on the integrity of nanofibers are relatively unclear. In Physics of Fluids, researchers examine these ambiguities through a visualization of nanofibers interacting with water aerosol exposure. They used high-speed microscopic videos to systematically visualize the evolution of nanofibers with different contact angles, diameters, and mesh sizes under water aerosol exposure.
Ultra-absorptive nanofiber swabs could improve SARS-CoV-2 test sensitivity
Researchers reporting in ACS’ Nano Letters have developed ultra-absorptive nanofiber swabs that could reduce the number of false-negative SARS-CoV-2 tests by improving sample collection and test sensitivity.
