Escherichia coli bacteria treated with citratereduced silver nanoparticles (AgNPs) are visualized using dark field scattering microscopy. The inset shows an AgNP spot on which surfaceenhanced Raman spectroscopy was carried out. The spectrum suggests that the interaction of AgNPs with bacterial DNA is one of the crucial steps in its antibacterial action. Thalappil Pradeep and co‐workers discuss further on page 1056.
