As linkers become increasingly sophisticated, more emphasis is being placed on the methods of bioconjugation between linker and antibody, with the goal of producing homogeneous adc populations. This architecture allows adcs to function as guided missiles in oncology—homing in on cancer. An antibody is linked to a small molecule via a covalent tether

Linker tethering payload to antibody is vital for adc
This review provides an overview of linkers of 17 approved adcs and recent innovations in linker design, focusing on drug release triggers, bioconjugation strategies, the impact of spacers on hydrophilicity, traceless drug release, and linker architecture, as well as a discussion of the bystander effect, offering insights for the rational. Provides target specificity by recognizing an antigen expressed primarily on tumor cells Chemically connects the antibody to the drug and controls its release
