We have studied bioconjugation of Bovine Serum Albumin (BSA) and DNA with colloidal silver nanoparticles. BSA and DNA modified silver nanoparticles were characterized using UV-Vis spectroscopy and FTIR studies. The emergence of new peaks in UV-Vis spectra corresponding to these biomolecules without shift in surface plasmon peak of silver nanoparticles showed successful modification of metal nanoparticles with BSA and DNA. FTIR spectra also supported these results.
