Gold Nanorods – Carboxyl

Description

Carboxyl Gold Nanoparticles are engineered with surface carboxylic acid groups, facilitating covalent conjugation to amine-containing biomolecules through EDC/NHS chemistry. This stable linkage is essential for various biomedical applications.

Applications:

• 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.
