Lasers Can Target And Destroy Nanocomposite Labeled Cancer Cells

Abstract:
A nanocomposite particle can be constructed so that it has a mix of properties that would not otherwise happen in nature. By combining an organic matrix with metallic clusters that can absorb light, it is possible to incorporate such particles into cells and then destroy those targeted cells with a laser. In a presentation at the NSTI Nanotech 2007 Conference, researchers describe work conducted at the NanoBiotechnology Center, Department of Radiation Medicine, Roswell Park Cancer Institute, Buffalo, NY and the University of Michigan, Ann Arbor, MI, regarding the creation and characterization of a dendrimer nanocomposite (DNC) matrix containing silver clusters that can be used to target and destroy melanoma cancer cells.

Composite NanoDevices (CNDs), are an emerging class of hybrid nanoparticulate materials. CNDs are made from dendrimer-based polymers, for example from poly(amidoamine) [(PAMAMs)].
