The sensitive detection of various neurotransmitters is very useful in diagnosing diseases related to the dysfunction of theneurotransmitter system. Surface-enhanced Raman scattering (SERS) is one of the best methods for bio-analyte detectionas it provides a molecular fi ngerprint at a trace concentration level. In this study, Ag-deposited porous silicon (Ag@pSi)was fabricated as a SERS-active substrate via metal-assisted chemical etching and electroless plating methods. Dopamine(DA) and norepinephrine (NE) neurotransmitters were tested as probing analytes. The Ag@pSi substrate demonstrated thesensitive detection of the neurotransmitters (DA and NE) over the wide concentration range (from 10 6 to 10 10 M), witha good linearity between the intensity of specifi c Raman peak and the log-scale concentration. The Ag@pSi substrate alsodistinguished the individual analytes in a mixture of DA and NE at 10 8 M, confi rming the effi cacy of the developed SERSsubstrate for the selective detection of neurotransmitters.
