摘要：

Silver particles, predominantly with the size of 40-80nm, 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 532nm laser wavelength is used and 10(-11)M at 633nm wavelength. Label-free detection is realized at these conditions. [GRAPHICS] (C) 2017 WILEY-VCH Verlag GmbH & Co. KGaA, Weinheim
