Actiframe is a technology spinout from the University of St Andrews that is developing materials to prevent spasm and blood clotting during vascular access procedures.
Our patented materials allow the release of an active agent called nitric oxide (NO) from the surface of vascular access devices. The released NO can prevent thrombosis and spasm – two frequently occurring problems when deploying these devices inside arteries.
Our goal is to reduce risk and discomfort to patients whilst making it easier and less expensive for clinicians to complete both routine and increasingly complex procedures.
Technical
Actiframe’s products are based on a class of materials called Metal Organic Frameworks (MOFs).
MOFs for Biomedical Applications
MOFs are microporous powders that can be loaded with biologically active and medically useful agents. Actiframe manipulates the highly tuneable chemistry of MOFs to integrate features that allow storage and controlled release of nitric oxide.1 Acting like reservoirs, our MOF products can be incorporated into coatings and formulations to provide controlled release of the active agent from device surfaces.2
Nitric Oxide
Nitric oxide is a gaseous biological signalling molecule that is critical to many functions within our bodies, including vasodilation and controlling platelet adhesion.3,4 Having the ability to controllably deliver NO artificially and enhance the body’s natural mechanisms is very relevant to many healthcare applications.
Being a gas, NO is inherently difficult to handle. Furthermore, administration of too much NO is highly dangerous. With our MOF technology however, we are able to release NO at the correct concentration, and at the preferred location over the required timescale to achieve the desired biological response, safely.
Formulating MOFs into your product
Achieving the correct formulation in appropriate matrices is critical to the successful application of MOFs to healthcare products. The technical team at Actiframe has over ten years’ experience of incorporating MOF powders into coatings, articles and formulations spanning many different product types. We work closely with our customers to ensure compatibility and optimal performance.
Biomedical MOF supply
Actiframe has developed proprietary methods for the manufacture of its products that remove the historic reliance by MOF researchers on toxic and environmentally undesirable solvents and energetically wasteful conditions.5 Actiframe manufactures MOFs at scale under cGMP protocols.
