Application of polymer microspheres to Raman detection
The invention discloses application of polymer microspheres to Raman detection. Methacrylate/amide polymer monomers or styrene polymer monomers containing alkynyl, cyano, azido or a carbon-deuterium bond group are prepared into the polymer microspheres with the particle diameter from a nanometer grade to a micron grade through an emulsion polymerization or dispersion polymerization method; the polymer microspheres have a remarkable Raman signal under the condition of no metal sensitization structure; and a Raman characteristic peak signal is located in a Raman quiet zone (1800cm to 2800cm) in a living organism and can be used as a marker for biological imaging.
