Simple pH Adjustment May Enable a Preventative COVID-19 Nasal and Throat Spray

A prototype patch made of hybrid nylon/silver vents that open in response to a person’s sweat and close again once dry. Requiring no energy, the vents open because the moist nylon must expand but the silver can only curl in on itself.

Innovative Textile Vents to Release Heat When You Sweat

Moisture opens the vents, rather than electronics

There are no physical structures in this video. The “walls” guiding the particles through the liquid are actually a complex combination of sound waves created by a new technique called a shadow waveguide.

Moving Tiny Things ... With Sound

This new biomedical device manipulates particles as small as DNA (2.5 nanometers) with sound-induced electric fields. Four transducers send sound waves into a substrate that creates electricity as it vibrates, producing patterns of electric-acoustic waves
