Scientists from the Massachusetts Institute of Technology are using nanoparticles to tackle drug-resistant bacteria, according to a study published in Advanced Materials.
Gram-negative bacteria are particularly difficult to treat, since they are protected by two cell membranes. But the team of Cambridge-based researchers reported that antimicrobial peptides inside of a silicon nanoparticle effectively reduced the number of bacteria in mice infected with Pseudomonas aeruginosa – a Gram-negative bacterium that can cause pneumonia.
