About Minamo
Minamo is a 2023 spinoff from the University of Iceland that develops patent-protected, antimicrobial silicone coatings designed to prevent healthcare-associated infections and biofouling. The company's technology is a two-step process involving environmentally friendly surface activation with hydroxyl amines in a non-toxic solvent, followed by biomolecule coating to confer antimicrobial properties. This approach seeks to enhance the biocompatibility of medical devices, such as implants and orthotics, without relying on toxic additives or antibiotics. By creating surfaces that deter bacterial adhesion, Minamo aims to improve patient safety and long-term device performance in clinical environments.
The technology is significant for the medical device industry as it addresses the critical challenge of infections related to silicone-based medical equipment. Through grants from organizations such as the Icelandic Technology Development Fund and recognition in international innovation forums, Minamo has demonstrated potential for scaling its research. The company actively engages with the global medical and silicone industries to forge collaborations and refine its solutions, aiming to provide a safer, more sustainable alternative that avoids occupational hazards and regulatory barriers typically associated with traditional antimicrobial treatments.
