3-Arm PEG10000-Azide
3-Arm PEG10000-Azide (3-Arm PEG10000-N3) is a three-armed PEG derivative. The core structure of 3-Arm PEG10000-Azide consists of three PEG chains, each terminal of which is modified with an azide (-N3) group. The azide group in 3-Arm PEG10000-Azide can undergo click chemistry reactions and is used for applications such as constructing targeted drug delivery systems and nanoparticle modification.

Biological Activity
The structure of PEG-Azide contains two key parts that work synergistically:
Azide group: can undergo a copper-catalyzed azido-yne cycloaddition reaction (CuAAc) with molecules containing an Alkyne group. It can also undergo ring-strain-driven acetylene-azidocycloaddition (SPAAC) reactions with molecules containing DBCO or BCN groups.
PEG chain: As a hydrophilic spacer, it forms a hydration layer on the particle surface, reducing non-specific adsorption and immune system recognition and clearance, thus prolonging the carrier's circulation time in vivo.
