The National Science Foundation awarded a $1 million grant to a team of five researchers at Stevens Institute of Technology to develop "smart" nanohydrogels that can control whether bacteria will adhere to synthetic surfaces. The goal is to create differentially adhesive surfaces that are adhesive to certain types of cells in the body but repel bacteria, in order to develop more infection-resistant biomedical implants. The researchers hope to design nanohydrogels that will either attract or repel cells through self-assembly of polymer nanoparticles coated onto surfaces.
