For the first time, a novel EpCAM aptamer (SYL3C)-DIBO-AF594 fluorescent conjugate was synthesised by bioorthogonal chemistry utilizing a strain promoted alkyne–azide cycloaddition (copper free click) reaction (SPAAC). The obtained conjugate showed target specific binding and aided in the imaging of various EpCAM positive cancer cell lines like MCF-7, MDA-MB-453, Weri-RB1 and PC-3.
