Biotin-PEG-Thiol (Biotin-PEG-SH, SH-PEG-Biotin) is a compound that combines the properties of biotin, polyethylene glycol (PEG), and a thiol group (-SH). The thiol group provides reactive chemistry, enabling covalent attachment to surfaces, nanoparticles, or other thiol-reactive molecules. Thiol chemistry is widely used for bioconjugation and surface modification due to its stability and specificity. PEGylation can improve the pharmacokinetics of therapeutic molecules by prolonging circulation time and reducing immune response. Biotin can facilitate targeted delivery to specific tissues or cells expressing avidin/streptavidin receptors.
