Novel technique allows to individually select droplets for contact in droplet-array sandwiching

Miniaturization is rapidly reshaping the field of biochemistry, with emerging technologies such as microfluidics and "lab-on-a-chip" devices taking the world by storm. Chemical reactions that were normally conducted in flasks and tubes can now be carried out within tiny water droplets not larger than a few millionths of a liter.

University of Liverpool signs option agreement with BARD1 for type 3C diabetes test

The University of Liverpool has signed a two year option agreement with the Australian diagnostics company, BARD1 Life Sciences Ltd (ASX: BD1), for a type 3c diabetes (T3cDM) blood test. The test uses patented technology developed by researchers in the University of Liverpool's Institute of Systems, Molecular and Integrative Biology.

Synthetic defective SARS-CoV-2 could be used as a self-promoting antiviral therapy

What if the COVID-19 virus could be used against itself? Researchers at Penn State have designed a proof-of-concept therapeutic that may be able to do just that. The team designed a synthetic defective SARS-CoV-2 virus that is innocuous but interferes with the real virus's growth, potentially causing the extinction of both the disease-causing virus and the synthetic virus.
