New flexible, transparent, wearable bio-patch, improves cellular observation, drug delivery

12.11.2018 | Purdue University | www.purdue.edu

Purdue University researchers have developed a new flexible and translucent base for silicon nanoneedle patches to deliver exact doses of biomolecules directly into cells and expand observational opportunities.

This means that eight or nine silicon nanoneedles can be injected into a single cell without significantly damaging a cell. So we can use these nanoneedles to deliver biomolecules into cells or even tissues with minimal invasiveness,” said Chi Hwan Lee, an assistant professor in Purdue University’s Weldon School of Biomedical Engineering and School of Mechanical Engineering.

New bio-patch

Silicon nanoneedles patches are currently placed between skin, muscles or tissues where they deliver exact doses of biomolecules. Commercially available silicon nanoneedles patches are usually constructed on a rigid and opaque silicon wafer. The rigidity can cause discomfort and cannot be left in the body very long.
