As antibiotic resistance quietly reshapes the boundaries of modern medicine, researchers have turned to the nanoscale for answers — engineering a silver-infused ceramic compound that can both kill resistant bacteria and dismantle the fortified communities they build to survive. Working with hardystonite, a calcium zinc silicate, a scientific team has demonstrated that the geometry of a material's surface, sculpted at dimensions invisible to the eye, may be as decisive as its chemistry. The findings open a considered path toward medical coatings and devices that do not merely resist infection b
