Abstract
Fluorescent metal nanoclusters were prepared.
Claims34
A method for preparing fluorescent nanoclusters, comprising:
- mixing an aqueous solution of a template and a metal precursor at a temperature that prevent the substantial formation of non-fluorescent metal nanoclusters and nanoparticles but allows the formation of a complex between the template and metal from the metal precursor, whereby a complex forms between the template and metal from the metal precursor;
- and
- increasing the temperature, whereby the complex is reduced and fluorescent metal nanoclusters are produced.
A method for preparing fluorescent metal nanoclusters, comprising:
- mixing a solution of a metal precursor and a polypeptide at a temperature and for an amount of time sufficient to convert at least some of the metal precursor to fluorescent metal nanoclusters.
A method of preparing fluorescent metal nanoclusters, comprising:
- mixing a two-phase liquid system comprising an aqueous phase and an organic phase, the aqueous portion comprising a biocompatible reducing agent and a template, the organic portion comprising metal precursor, the metal chosen from gold and silver, the template chosen from dendrimers, polypeptides, and proteins;
- separating the aqueous phase from the organic phase after mixing the two-phase liquid system;
- and
- heating the aqueous solution.
