Multifunctional Nanoparticles Can Target, Separate and Destroy Bacteria

JSU & UT San Antonio team members have reported the development of multifunctional popcorn shape iron magnetic core- gold plasmonic shell nanotechnology-driven approach for targeted magnetic separation & enrichment, label-free surface enhanced Raman spectroscopy detection, and selective photothermal destruction of MDR Salmonella DT104. Our result shows that magnetic core–plasmonic shell popcorn shape nanoparticle based assay is rapid, takes about 30 minutes from bacterium binding to separation, enrichment, selective detection and photothermal killing.
