The Department of NanoMedicine and BioMedical Engineering

Nano Chemistry Service Center

The Nano Chemistry Service Center provides custom synthesis, labeling, and chemical coupling of DNA thioaptamers and nanoparticles. The Director and Lab Manager are both Ph.D. chemists with years of experience in DNA synthesis, especially the more difficult monothioated and dithioated DNA. In addition, they have conjugated numerous dyes, chelators, chemical linkers, and DNA spacers onto DNA. They have conjugated such DNA aptamers to liposomes, gold nanoparticles and mesoporous silicon particles for multi-stage vectors.
