Abstract
Metal nanoparticles associated with a spectroscopy-active (e.g., Raman-active) analyte and surrounded by an encapsulant are useful as sensitive optical tags detectable by surface-enhanced spectroscopy (e.g., surface-enhanced Raman spectroscopy).
Claims30
A particle comprising:
- a surface-enhanced spectroscopy (SES)-active metal nanoparticle;
- a SES-active label associated with said SES-active metal nanoparticle;
- and
- an encapsulant surrounding said SES-active metal nanoparticle and said spectroscopy-active label, wherein said encapsulant comprises a material selected from the group consisting of glass, polymers, metals, metal oxides, and metal sulfides, and wherein said particle has a measurable SES spectrum.
