Abstract
A method of stabilizing particles with an insulating, semiconducting and/or metallic coating and stabilized particles prepared thereby are disclosed. In addition, particles stabilized by an insulating, semiconducting and/or metallic coating, wherein said coating is attached to said particles via a bifunctional ligand are provided, as is a method is provided for determining the presence of an analyte in a sample comprising incubating the sample with a ligand bound to a coated particle, capable of specifically binding to the analyte and capable of providing a detectable signal and detecting the presence of a ligand-coated particle:analyte complex as indicating the presence of the analyte in the sample.
