Experimental and theoretical studies on sensing adenine by Ag, Au and Ag-Au bimetallic nanoparticles

摘要

Experimental and theoretical studies on sensing adenine by silver, gold andsilver-gold bimetallic nanoparticles are reported. UV-visible spectroscopy hasbeen used to study the surface plasmon resonance changes. The vibrational frequencies of adenine and silver complexedadenine have been compared with the HF theoretically calculatedfrequencies. It is demonstrated that adenine is adsorbed on the nanometallicsurfaces through chemisorption and this property can be effectively used tosense adenine.
