Our new paper in Acta Biomaterialia (Stewart et al, June 27, 2018) on the design and smart response of composite materials for dental applications, which contain microspheres packed with antimicrobial drug. These spheres were synthesized by a unique self-assembly that we developed previously (Stewart et al, Scientific Reports, Jan 2018), which allows 'surfactant-type' (ie; detergent-like) antimicrobial drug molecules to self-assemble with silicate (ie; glass) species and make a nanocomposite sphere (below). As a result, the drug makes up half the material! We're very excited about this kind of approach as a means to add much better antibacterial performance qualities to dental materials, and help prevent 'secondary caries' - cavities which form around existing fillings.
