a Representative (300 × 300) nm2 TEM micrograph of as-synthesized gold nanorods. b, c Relevant volumetric distributions of aspect ratios and volumes derived from the analysis of around 500 particles. d spectrum of optical extinction of a suspension of pLys-coated gold nanorods. e, f Representative images of untreated controls and macrophages exposed to 400 µM Au pLys-coated gold nanorods for 24 h, from a confocal microscope (TCS SP8, Leica Microsystems, Heidelberg, Germany) operated in transmission mode at 63× magnification
