40 nm Gold Nanoparticles

• Bare surface for efficient conjugation
• Laser-made for high purity and stability
• Optimized for Lateral Flow assay development

$100.00 – $700.00

Overview
The high purity, stability, and bare surface of i-colloid 40 nm gold nanoparticles allows efficient conjugations and reproducible conjugate performance in lateral flow immunoassays. IMRA’s laser-ablation process allows Au40 to be a cost-effective solution for assay development.

Features and Advantages
• Stable without capping agents or surfactants
• Each batch QC tested for consistent performance
• High contrast with Gold-Platinum in dual-color assays
• Laser-made for highest purity
