Nanodiamonds move into gene therapy

By / September 2, 2009

A team of Northwestern University researchers has figured out a way to use nanodiamonds to deliver DNA for gene-therapy application. By modifying the surface of nanodiamond particles with a special polymer, a group led by Dean Ho found they could reach a delivery efficiency that is 70 times greater than that of a conventional standard…

Multifunctional material aids brain imaging

By / August 17, 2009

Engineers are getting craftier and craftier about making one material that is capable of more than one function, especially in the realm of nanomaterials. It can be a little difficult to exactly understand what this is all about, but the basic idea is that if you are going to all the trouble to try to…
