Laser-fabricated, surfactant-free
The 40 nm Gold-platinum nanoparticles are fabricated by pulse-laser ablation.
Product Features:
- High biomolecule conjugation with no capping agents or surfactants
- Homogeneous Gold and Platinum distribution
- Black color from absorption across entire visible spectrum
- High purity and colloidal stability
- Size optimized for lateral flow immunoassays
- Use with 40 nm gold nanoparticles for multiplex lateral flow
Specifications:
- Average Size (by disc centrifugation): 40 ± 5 nm
- Gold-Platinum absorbs in entire visible spectrum: OD is measured at 400 nm
Protocols:
- Passive Conjugation of Proteins to i-colloid 40 nm Gold and Gold-Platinum
- i-colloid Gold and Gold-Platinum Conjugation Optimization
Technical Notes:
- Equivalent Performance of i-colloid 40 nm Gold and Gold-Platinum
- Multicolor, Multiplex Lateral Flow with i-colloid Nanoparticles
