Products Overview

Background - gold nanoparticles Gold nanoparticles so small they appear intensely red and remain suspended in water enable rapid, point of care (or POC) assays to detect minute traces of important substances. To accomplish this feat, nano-gold particles (gold sol) must be coated with appropriate receptors that react specifically with the molecules to be detected. BioAssay Works creates gold sols used in ultra-sensitive, rapid-diagnostic tests. The company employs these gold sols to develop state-of-the-art POC assays.

Features and Benefits of BioAssay Works Products:

• A 10- to 15-fold increase in gold-nanoparticle concentration over existing technology. 15- to 50-OD (optical density) gold nanoparticle sols, versus 1-OD produced by conventional technology protocols
• Ready-to-use gold-particle sols (no concentration required)
• Laboratory time, labor, and cost savings (no centrifuging required)
• Increased consistency in product quality
• 10%-20% reduction in manufacturing waste, and increased manufacturing efficiency (reduced waste of gold particles and precious antibodies and antigens)
• Uniform monomer particles: no aggregates
• Customers who manufacture their own diagnostic products will find that the 15- to 50-OD formulations significantly improve their process, while also reducing costs
• Improved reproducibility of all rapid-diagnostic products
• Reduced laboratory and production costs leads to increased profits

BioAssay Works creates gold sols and gold-sol-based assays with industry-leading performance characteristics. With our technology and expertise, we solve a problem of gold-particle concentration that exists with conventional technology and all competitive products.
