An Encoded Microsphere

Abstract

There is disclosed a method for encoding a microsphere comprising the steps of i) providing a layer of a polyionic polymer to the microsphere, ii) coating the layer with quantum dots, iii) providing a layer of a transparent polyionic polymer to the coated polymer layer and iv) coating the transparent layer with the same and/or different quantum dots and, optionally, repeating steps iii) and iv) whereby to characterise the microsphere by the wavelength and/or intensity of its photoemission spectrum on excitation at a predetermined wavelength of incident light.
