Abstract
Gold nanoparticles were successfully deposited onto a poly(tetrafluoroethylene) (PTFE) membrane filter by pulsed 532-nm laser irradiation in a 2-propanol solution containing HAuCl 4. The resulting membrane filters were used as substrates for infrared (IR) absorption spectrometry. A substantial enhancement in the IR spectrum of L-cysteine was observed by using this substrate. The degree of enhancement was roughly twice compared with the case of PTFE membrane filters without gold nanoparticles.
