Background of lspr
what is lspr? what are five main different types of lspr-based sensing strategies using metal nps, including:
- detection of their lspr absorbance/scattering or color using them as labels;
- bulk refractive index sensing of the medium by direct detection of the lspr wavelength shift;
- detection of local analyte binding by direct detection of the lspr wavelength shift;
- detection of a lspr wavelength shift by analyte-induced metal np aggregation; and
- detection of analyte induced distance changes in linked metal.
