News Articles Featuring Ayusman Sen

Artificial cells act more like the real thing

Protocells -- artificial cells -- that are active and mimic living cells by moving independently and that are biocompatible and enzymatically active are now possible using an improved method developed by Penn State researchers.

Directing Self-propelled Protocells To Deliver Drugs

Synthetic protocells can be made to move toward and away from chemical signals, an important step for the development of new drug-delivery systems that could target specific locations in the body. By coating the surface of the protocells with enzymes — proteins that catalyze chemical reactions — a team of researchers at Penn State was able to control the direction of the protocell’s movement in a chemical gradient in a microfluidic device.

Directional control of self-propelled protocells: The future of drug delivery?

Tiny swimming donuts deliver the goods

Bacteria and other swimming microorganisms evolved to thrive in challenging environments, and researchers struggle to mimic their unique abilities for biomedical technologies, but fabrication challenges created a manufacturing bottleneck. Microscopic, 3D-printed, tori — donuts ­­— coated with nickel and platinum may bridge the gap between biological and synthetic swimmers, according to an international team of researchers.
