Abstract

Silver particles, predominantly with the size of 40–80 nm, were immersion deposited onto porous silicon to form substrates appropriate for the detection of organic molecules by surface-enhanced Raman scattering technique. These substrates have been demonstrated for the first time to provide detection of phospholipid molecules represented by dipalmitoylphosphatidylcholine at concentrations as low as 10−12 M when a 532 nm laser wavelength is used and 10−11 M at 633 nm wavelength. Label-free detection is realized at these conditions.
