A method of using a bioconjugated upconversion luminescent nanoparticle system for biological labeling, comprising the steps of:
- delivering a bioconjugated upconversion luminescent nanoparticle system to a target,
- binding the bioconjugated upconversion luminescent nanoparticle system to the target, and
- measuring upconversion luminescence from the bioconjugated upconversion luminescent nanoparticle system bound to the target,
- wherein an emission wavelength of the bioconjugated upconversion luminescent nanoparticle is shorter than an excitation wavelength of the bioconjugated upconversion luminescent nanoparticle.
A method of using a bioconjugated upconversion luminescent nanoparticle system for detecting an analyte, comprising the steps of:
- binding an analyte to a bioconjugated upconversion luminescent nanoparticle,
- allowing the analyte to transfer energy with the bioconjugated upconversion luminescent nanoparticle thereby producing signal changes,
- measuring the signal changes, and
- processing the signal changes;
- wherein an emission wavelength of the bioconjugated upconversion luminescent nanoparticle is shorter than an excitation wavelength of the bioconjugated upconversion luminescent nanoparticle.
