COVID-causing virus in air detected with high-tech bubbles

Scientists have shown that they can detect SARS-CoV-2, the virus that causes COVID-19, in the air by using a nanotechnology-packed bubble that spills its chemical contents like a broken piñata when encountering the virus.

Optical indicators based on cholesteric liquid crystal polymers

Optical indicators based colored polymers are autonomous responsive labels that provide an optical signal to represent a specific exposure over time. Polymers that possess a high degree of order can establish structural color, ...

Dense liquid droplets act as cellular computers

An emerging field explores how groups of molecules condense together inside cells, the way oil droplets assemble and separate from water in a vinaigrette.
