摘要：

A silver-coated capillary tube was chemically prepared at room temperature and its performance as a surface-enhanced Raman scattering (SERS) active substrate was tested using p-nitrophenol (PNP), Rhodamine 6G and p-chlorobenzoic acid (PCBA) as analytes. The optimum time for the silver deposition was determined by using PNP as the analyte. Two different methods of sample application were tested and adapted. The surface enhancement effect of the substrate was found to be comparable to that of a silver-coated plate. Other studies were carried out to test both the efficiency of the substrate resulting from pretreatment of the tube and also the reusability of the substrate. Advantages of using the capillary substrate in SERS detection are discussed.
