Silver nanoparticles, AgNPs, are widely used in our daily life, mostly due to their antibacterial, antiviral, and antifungal properties. However, their potential toxicity remains unclear. In order to unravel this issue, emissive AgNPs were first synthetized using an inexpensive photochemical method, and then their permeation was assessed in vivo in goldfish… (More)
Fast electron based spectroscopies are often loosely compared to light scattering. By performing Electron Energy Loss Spectroscopy and Cathodoluminescence on single metallic nanoobjects, we show that these techniques are nanometric probes of extinction and scattering.
