Targeted molecular imaging probes are essential tools for visualization of specific molecular processes in cells and living systems. Among these, targeted fluorescent probes are widely used due to the high sensitivity and resolution of fluorescence imaging. The conventional strategy for developing targeted fluorescent probes is to couple targeting ligands with fluorescent dyes by covalent bond via bioconjugation. Here, we describe several commonly used bioconjugation methods, from traditional amide and thiol coupling, to metal-catalyzed coupling reaction and catalyst free cycloaddition.
