Biotin Gold Nanoparticles
These Gold nanoparticles are functionalized with Biotin-terminated Polyethylene Glycol (PEG).
The presence of surface biotin groups facilitates specific and strong binding to streptavidin or avidin-conjugated biomolecules. This interaction is widely utilized in various biomedical applications.
Applications of biotin gold nanoparticles:
- Development of lateral flow assays for rapid diagnostics
- Surface-enhanced Raman spectroscopy (SERS) for molecular detection
- Targeted drug delivery systems in therapeutic research
These nanoparticles are characterized by a narrow size distribution and high colloidal stability, ensuring consistent performance in complex biological environments.
