Abstract
A method to link a light emitting reporter to biomolecules with nucleotide oligomers is described. The light reporter particles are silylated and functionalized to produce a coated light reporter particle, prior to covalently linking the biomolecules to the light reporter particle. The light reporter particle generated by the methods of the invention can be excited by a light excitation source such as UV or IR light, and when the biomolecule is DNA, the attached DNA molecule(s) are detectable by amplification techniques such as PCR.
