• Can be used with gold for multicolor multiplex assays
$150.00 – $270.00
Overview
Gold-platinum alloy nanoparticles (AuPt) have a black color for optically distinct assays from gold or multicolor, multiplex assays when used with gold. Gold-platinum also has a peroxidase-like activity that allows catalytic signal amplification for more sensitive detection.
Features and Advantages
• Efficient conjugation to laser-fabricated bare surface
• Passive conjugation protocols and conditions like gold
• Peroxidase-like activity for catalytic signal amplification
