Cool nanotech image — microneedles

Cool to look, even more cool when put into practice. Microneedles can deliver quantum dots into skin and should lead to new diagnosis and treatment of medical conditions such as skin cancer.

And now, the image:

Hollow microneedles open the door to new techniques for diagnosing and treating a variety of medical conditions, including skin cancer. Image reproduced by permission of the Royal Society of Chemistry.

Improving thin-film coatings

This research affects solar cells and a host of other applications.

From the link:

Understanding how thin-film coatings react to temperature changes could lead to more effective and durable sensors, solar-energy converters, safer medical implants and a host of other applications, says Jodie Lutkenhaus, assistant professor in the Artie McFerrin Department of Chemical Engineering at Texas A&M University, who has found that heating some of these films can increase their stability.

The findings, which appear in an upcoming issue of Soft Matter, a scientific journal published by the Royal Society of Chemistry, represent a significant step forward in the study of multilayer polymer thin-film coatings — material gaining increased interest for its potential versatility in a number of applications ranging from biomedical to industrial.
