From: Polylysine as a functional biopolymer to couple gold nanorods to tumor-tropic cells
Migration (upper panel) and release of pro-inflammatory cytokines (lower panel) from macrophages loaded with gold nanorods by incubation with a dosage of 400 µM Au for a period of 24 h and then exposed to specific pro-inflammatory stimuli for another period of 18 and 24 h, respectively. The quantification of cytokines in the samples treated with particles is expressed as percent of untreated controls, always in the presence of LPS (no cytokines were found in the absence of LPS). Results are shown as mean ± SD of three independent experiments
