Metal coated nanocrystalline silicon as an active surface enhanced raman spectroscopy (sers) substrate

Method and device publicizes pertain is a metal coating the nano crystal porous silicon-based target aluminium Raman spectrograph method. The porous silicon matrix is arranged on the front ion corrosion is formed on the thin hydrofluoric device. By using the negative electrode for or any known technology, After active metal's thin layer is one corrosion to the mapping silicon, which is an active metal such as a metal or silver. The fields, the coated with metal porous silicon matrix comprises a mapping silicon matrix for plasma an deoxidation potential meter probe/ph valve, wherein dips and decomposition. The coated with metal matrix is SERS, SERBS, wherein After and/or CARS Raman spectrograph method of claims delaying, wherein the metal rich environment. The fields, metal with particles is added the is provided with a metal matrix, a line is Raman signal. The bus method and device, Raman spectrograph method can be used on the detections, appraisals and/or quantitative a analytes. Of claims a method, Raman spectrograph method can be used in layer of single molecule, detecting nucleotide, purine or metadiazine.
