Govorov Explores Efficient and Reversible Chirality Induction
Dr. Alexander Govorov and colleagues published "Efficient and reversible chirality induction between protein and achiral plasmonic assemblies" in the Journal Nature Materials. They show "that the mechanical stretching of protein molecules anchored within achiral gold nanoparticle assemblies strongly enhances and reversibly modulates plasmon-coupled circular dichroism."

Biotesting with Less Expensive Materials: Replacing Colloidal Gold
Lateral flow testing technology has been around for decades, but only recently received widespread use and attention during the coronavirus pandemic in the form of COVID-19 tests. A large part of what makes most lateral flow assay (LFA) tests function is gold. The OHIO team’s work consisted of using titanium nitride (TiN) and gold-covered copper (Cu@Au) nanoparticles as components in test kits for the first time.
