Abstract
An encapsulated surface enhanced Raman scattering (SERS) tag. The tag includes a metal core and an encapsulant, typically a glass encapsulant. The encapsulant is further derivatized with a polymer.
Claims4
A coated nanotag comprising:
- a SERS active nanotag;
- and
- a polymer coating around at least a portion of the SERS active nanotag.
A method of tagging a tissue, comprising associating said tissue with a polymer coated SERS active nanotag.
A method of manufacturing a coated nanotag comprising:
- a) associating a spectroscopy-active analyte with a surface-enhanced spectroscopy (SES)-active metal nanoparticle;
- b) coating said analyte-associated metal nanoparticle with an encapsulant;
- wherein said spectroscopy-active analyte has a measurable SERS spectrum;
- and
- c) coating said encapsulated particle with a polymer.
2 more elements
A method of assaying tissue comprising:
- associating said tissue with a polymer coated SERS active nanotag;
- and obtaining the Raman spectrum of the polymer coated nanotag.
