QuantumSphere

QuantumSphere is a nanotechnology company that specialized in the production of high-purity metal and alloy nanoparticles using its proprietary Automated Vapor Condensation (AVC) process. The company's primary healthcare contribution involved the development of "QSI-Nano" silver and copper nanoparticles, which were utilized for their potent antimicrobial properties in medical device coatings and wound care applications. Their technology platform allowed for the creation of highly consistent, non-agglomerated particles with high surface area-to-volume ratios, optimizing biological interaction and efficacy. Despite achieving commercial-scale production and establishing partnerships for its nanomaterials, the company faced financial insolvency and filed for bankruptcy in 2018.
