Description
General Description
Folate-poly(ethylene glycol)-azide (FA-PEG-N₃) is a heterobifunctional PEG derivative featuring folic acid for receptor-mediated targeting and an azide group for bioorthogonal click chemistry reactions.
Key Properties
- Folate (folic acid) targeting ligand
- Azide (-N₃) functional group for click chemistry
- PEG spacer improves solubility and biocompatibility
- Suitable for receptor-targeted systems
- Water-soluble bioconjugation linker
Applications
- Targeted drug delivery systems (folate receptor targeting)
- Nanoparticle surface functionalization
- Click chemistry bioconjugation (CuAAC / SPAAC)
- Cancer-targeted therapeutic systems
- Imaging and diagnostic probe development
- Biomaterial surface engineering
Functional Overview
The folate group enables selective binding to folate receptors, while the azide group allows efficient and selective conjugation via click chemistry, making this molecule highly versatile for targeted delivery platforms.
Summary
Folate-PEG-azide is a multifunctional targeted PEG linker widely used in drug delivery, bioconjugation, and receptor-mediated targeting applications.
