摘要
A Raman detecting chip for thin layer chromatography and a method for separating and detecting an analyte are provided. The Raman detecting chip for thin layer chromatography includes a silicon substrate. The silicon substrate includes a first portion, a second portion and a plurality of silicon nanowires disposed on the first portion, wherein each silicon nanowire has a top surface and a sidewall. A metal layer covers the top surface and at least a part of the sidewall of the silicon nanowire, wherein the silicon nanowire has a length L from 5 μm to 15 μm. The ratio between the length L1 of the side wall covered by the metal layer and the length L of the silicon nanowire is from 0.2 to 0.8.
