Functionalization of nanoparticles and immobilization of biomolecules on nanoparticles are important techniques for various applications in biotechnology. For application in the biomedical field, the surface of ultradispersed diamond (UDD) is immobilized with amino-terminated DNA after functionalizing carboxylic or amino group on the UDD surface. The characterized surface of UDD, carboxylated UDD, and aminated UDD were analyzed by DRIFT spectroscopy. In addition, hybridization with Cy-5 labeled target DNA was clearly observed on functionalized UDD by fluorescence microscopy.
