Surface-enhanced Raman scattering of adenosine triphosphate molecules

[[abstract]]Surface-enhanced Raman scattering (SERS) of adenosine triphosphate molecules (ATP) adsorbed on silver electrodes is studied. Voltage dependence, concentration dependence, and pH value dependence of the SER spectra are presented. All these can be understood by considering that these molecules are adsorbed on the silver electrodes through adenine rings with end-on or flat-on orientation. The effect of divalent metal on the spectra is discussed.[[fileno]]2010124010034[[department]]物理
