Application

Biotin-poly(ethyleneglycol)amine (BPEG) is used to functionalize (biotin pegylate) surfaces of structures such as hydrogels, microspheres, quantum dots and nanoparticles to take advantage of biotin-avidin based targeting.
Biotin-poly(ethyleneglycol)amine may be used as a crosslink horse radish peroxide (HRP) enzyme to the surface of silver island films (SIFs). 1 Biotin PEG amine may be used to functionalize the surface of poly(lactic-co-glycolic acid) (PLGA) nanoparticles.
