Bioconjugation is a chemical process that involves linking biomolecules, such as proteins, nucleic acids, or carbohydrates, to other molecules, often for research or therapeutic purposes. This technique is widely used in fields like biotechnology and pharmaceuticals to create targeted drugs, improve imaging techniques, or develop diagnostic tools. The process typically employs various methods, including click chemistry and cross-linking, to ensure that the biomolecules retain their biological activity. By attaching different functional groups or labels, scientists can enhance the properties of the biomolecules, making them more effective for applications like drug delivery or molecular imaging.
