Widely used in biomedical research for targeting integrin receptors, especially αvβ3, which are overexpressed in tumor cells and during angiogenesis. Enables specific delivery of imaging agents and therapeutic compounds to cancer cells. Frequently employed in PET imaging by conjugating with radionuclides for non-invasive tumor detection. Also applied in drug delivery systems to enhance the selectivity of nanocarriers and reduce off-target effects. Supports cell adhesion studies in tissue engineering due to its high affinity for integrins on cell surfaces.
