Abstract

original image

Click by click: Dual labeling of model compounds was carried out by using copper-free and copper-mediated click chemistry in a sequential manner. This method was used to introduce two labels onto biological targets or nanoparticles, thus quickly converting them into fluorescence resonance energy transfer systems.
