Nanotechnology: Coating Porous Stainless Steel and Glass Slides with Titanium Dioxide Nanoparticles

submitted by: cranberrylab

This video was created by students in the CHE230X/ME230X: Nanobiotechnology Laboratory Experience course at Worcester Polytechnic Institute. In this video, students synthesize titanium dioxide nanoparticles using the sol-gel technique. They then demonstrate how to coat porous stainless steel and glass slides with the nanoparticles. This work was funded in part by the National Science Foundation (EEC 0941746).

Safer Nanoparticle Spotlight Tumors, Deliver Drugs

submitted by: ucsandiego

Small is promising when it comes to illuminating tiny tumors or precisely delivering drugs, but many worry about the safety of nano-scale materials. Now, a team of scientists has created miniscule flakes of silicon that glow brightly, last long enough to slowly release cancer drugs, then break down into harmless byproducts.
