Biotin-PEG-silane is a bi-functional polymer containing both a biotin moiety and a polyethylene glycol (PEG) chain attached to a silane group. The biotin moiety is a vitamin-like compound that is widely used as a probe in biological and biomedical research due to its high affinity for avidin and streptavidin proteins. The PEG chain confers excellent water solubility and biocompatibility to the polymer.

Biotin-PEG-silane has been employed in various applications in pharmaceutical research, including drug delivery, tissue engineering, and diagnostics. Its unique chemical properties allow for the covalent attachment of biotinylated biomolecules, such as proteins and antibodies, to a surface, such as a drug carrier or a biosensor. This process results in the formation of a stable and specific linkage between the biomolecule and the surface, enabling the precise targeting of therapeutic agents or the sensitive detection of biological molecules.

Furthermore, Biotin-PEG-silane has also been used as a surface modifier for biomedical devices, such as implants and biosensors. The silane group can be covalently bound to a variety of substrates, including glass, metal, and polymer surfaces, allowing for the immobilization of biotinylated biomolecules for various applications.
