Started in 2016, X4C is a spin-off company from the Brussels University (ULB), Belgium. We are developing and commercializing molecular surface coating technologies, based on proprietary small organic molecules called calix[4]arenes. By enhancing the surface properties, and through a versatile bioconjugation approach, next generation surfaces and nanoparticles are created. Further immobilization of biomolecules leads to high performance materials for Life Sciences applications.Our activities are supported by 2 patents families and numerous peer-reviewed publications. We are proud of our scientific origins, and we constantly keep our R&D at the highest level, while understanding and supplying our customers with highly performing products and services. We like collaborations, because we are convinced that the success of a project is a perfect combination of our and our customers expertise. We continuously strive for intensive and flexible co-operation with our customers and partners.
