Bioconjugation is a specialized skill that involves the covalent attachment of two or more biomolecules, typically a protein or peptide, to another molecule or surface. The process requires specific chemical functional groups to be present on the biomolecules and the surface. Bioconjugation is widely used in biomedical research and drug development to create novel bioactive molecules, as well as in diagnostic assays and imaging technologies. The technique requires specialized knowledge of chemistry, biology, and materials science, and is typically carried out by experts in the field.
