Nanoparticles represent an interesting class of materials that can be used to enhance regenerative treatments by enabling close control over surface properties and directing cellular responses. At MERLN, inorganic nanoparticles that vary in terms of content, shape, surface modifications and morphology are developed to create new generations of biomaterials with changeable features at the nanoscale. Additional focus is on using nanoparticles to temporally control the delivery of (multiple) biochemical compounds and for imaging applications.
