Abstract
A method for assessing a state of a living cell using surface enhanced Raman spectroscopy (SERS) is provided. The method may include modifying one or more living eel Is with an alkyne-containing compound to form one or more modified living cells, mixing the one or more modified living cells with a SERS-active material to form a mixture, injecting the mixture into a conduit defined by an inner wall of a hollow core photonic crystal fiber, and detecting a surface enhanced Raman signal from the mixture in the conduit. In preferred embodiments, the alkyne containing compound is linoleamide alkyne (LLA) for the detection of lipid peroxidation or 4-(dihydroxyborophenyl) acetylene (DBA) for the detection of sialic acid expression in cells, both using gold nanoparticles as the SERS-active material.
