Medchemexpress LLC m-PEG-thiol (MW 1000) | 134874-49-0 | 98.0% | (C2H4O)nC3H8OS | 25 MG
Supplier: Medchemexpress LLC 25MGHY140708
m-PEG-thiol (MW 1000) is a surface modifier used to modify DNA thiolation and in the synthesis of gold nanorods (AuNR). It forms a covalent bond with the surface of gold nanoparticles through its thiol group, stabilizing them and enhancing biocompatibility. This substance provides a platform for subsequent coupling of biomolecules, promoting the functionalization of nanomaterials.
- Used for surface functionalization of gold nanorods (AuNRs)
- Modifies DNA thiolation
- Stabilizes nanoparticles by steric hindrance effect
- Enhances biocompatibility of nanoparticles
- Provides a platform for coupling biomolecules (such as DNA, antibodies)
- Can be used as a shielding layer to embed Raman reporter molecules or drugs
- Suitable for SERS imaging of cancer cells and construction of drug delivery systems
