Both, SPR- and LSPR-based sensors utilize the property that nanostructured thin film or particles are very sensitive to the dielectric constant change of their local environment, and the enhanced detection sensihvity really depends on how the nanostructures respond to such change. Although some of these techniques (especially SPR) are already available commercially, their sensihvity and specificity are relatively poor, especially for trace amounts of biomolecules or complicated systems such as viruses and bacteria. As stated above, metallic nanostructures-especially particles-may also enhance the local electric field when the incident wavelength is close to the LSPRW, and this provides yet another means of designing enhanced spectroscopic sensors, especially the so-called surface-enhanced vibrational spectroscopy (SEVS) sensors.
