Schematic of an antibody molecule combined with immunomagnetic particle and versatile immunomagnetic nanocarrier platform. Left: schematic of an antibody molecule combined with an immunomagnetic particle. The nanoparticle is composed of a gold shell and an iron oxide core. The surface is functionalized with a heterofunctional linker and polyethylene glycol terminated with dithiol group (PEG-SH) which are used to link the antibody and the nanoparticle. Right: a versatile immunomagnetic nanocarrier platform in microfluidics for capturing CTCs. (Adapted from [20]).
