The field of nanotechnology relies heavily on the ability to precisely control the surface properties of nanomaterials. Functionalization with specific molecules imparts desired characteristics, enabling applications in areas such as targeted drug delivery, biosensing, and advanced imaging. Biotin-PEG3-Azide (CAS 875770-34-6) emerges as a powerful tool in this domain, facilitating the attachment of biotin tags to various nanomaterial surfaces through efficient bioconjugation chemistries. As a dedicated chemical manufacturer and supplier, we provide this critical reagent to drive innovation in material science.

The unique structure of Biotin-PEG3-Azide, featuring a biotin head group and an azide tail linked by a flexible PEG3 chain, makes it exceptionally versatile for surface modification. The PEG3 linker offers several advantages: it increases the hydrophilicity of the nanomaterial surface, reduces non-specific protein adsorption, and provides a defined spacer arm that allows for optimal accessibility of the biotin moiety. The azide group serves as the anchor for conjugation, readily participating in click chemistry reactions with alkyne-functionalized surfaces or molecules.

Researchers can functionalize substrates, nanoparticles, or quantum dots with alkyne groups and subsequently react them with Biotin-PEG3-Azide to introduce biotin labels. This biotinylation is invaluable, as the biotin tag can then capture avidin or streptavidin, which can be further conjugated with other molecules such as antibodies, enzymes, or fluorescent dyes. This multi-step functionalization strategy allows for the creation of highly specific and sensitive diagnostic tools, targeted delivery vehicles, or advanced imaging agents.
