Catching bugs: A highly sensitive and fast detection system was developed for infectious agents. In this approach, bacteria were incubated with magnetic nanoparticles (MNPs), concentrated inside a microfluidic chamber, and detected with a miniaturized NMR chip. The method showed unprecedented sensitivity, detecting 20 bacteria in a 1 mL sample of sputum within 30 min.
