Bioconjugation is the process of chemically linking two biomolecules, such as proteins, nucleic acids, or sugars, together to create a new complex molecule. This technique is commonly used in research and industry to attach functional groups, labels, or other molecules to biomolecules for various purposes, such as detecting, isolating, or modifying them. Bioconjugation plays a crucial role in fields such as biotechnology, medicine, and biochemistry, where it enables the development of new diagnostic tools, therapeutics, and materials.
