Method for identifying microorganism or detecting its morphology alteration using surface enhanced ramam scattering (SERS)

摘要

The present invention relates to a method for producing a profile identifying a microorganism based on surface enhanced Raman scattering (SERS) and an apparatus thereof. The method comprises: (1) placing the microorganism on a SERS-active substrate; (2) mounting the microorganism with a mounting solution; (3) obtaining a SERS spectrum of the microorganism in step (2); and (4) analyzing the SERS spectrum to produce the profile.

The present invention also relates to a method for detecting morphology alteration of a microorganism due to an antimicrobial agent or an infectious agent based on SERS and an apparatus thereof. The method comprises: (1) placing the microorganism on a SERS-active substrate; (2) mounting the microorganism with a mounting solution; (3) treating the microorganism with a pharmaceutically effective amount of the antimicrobial agent or the infectious agent; (4) obtaining a SERS spectrum of the microorganism in step (3); and (5) identifying effect of the antimicrobial agent or the infectious agent by at least one new peak in the SERS spectrum in step (4) compared to a SERS spectrum of a control sample, wherein the control sample is not treated with the antimicrobial agent or the infectious agent.
