Johns Hopkins researchers design tiny, star-shaped microdevices to deliver drugs

Inspired by a parasitic worm that digs its sharp teeth into its host's intestines, Johns Hopkins researchers have designed tiny, star-shaped microdevices that can latch onto intestinal mucosa and release drugs into the body.

Rubbery bioelectronic cardiac patch can monitor and treat heart disease

Pacemakers and other implantable cardiac devices used to monitor and treat arrhythmias and other heart problems have generally had one of two drawbacks - they are made with rigid materials that can't move to accommodate a beating heart, or they are made from soft materials that can collect only a limited amount of information.

AI speech processing framework detects inaudible COVID-19 cough

Now, a team of researchers at the Massachusetts Institute of Technology (MIT) has found that asymptomatic people may differ from those who are healthy in the way they cough. The differences are inaudible to the human ear but can be detected by artificial intelligence (AI).

Engineers use electric fields to manipulate viruses in microfluidic device

The technique uses microfluidics -- the submillimeter control of fluids within a precise, geometric structure. On what is basically a tricked-out microscope slide, chemical engineers from Michigan Technological University have been able to manipulate viruses in a microfluidic device using electric fields.
