Biotin-PEG-Thiol (MW 2000)

Biotin-PEG-Thiol (MW 2000) is a heterobifunctional crosslinker used to functionalize nanomaterials. Its biotin moiety enables streptavidin-based detection and purification, while the thiol group allows conjugation to gold nanoparticles or other surfaces, facilitating applications in biosensing, drug delivery, and both in vitro and in vivo imaging studies.
