Fig. 4: Ex vivo stability and in vivo specificity of Ly6G NPs.

A, B MPI and FLI signals and corresponding curves for different concentrations of Ly6G NPs in test tubes. C–F MPI and FLI imaging were performed after mice were injected intramuscularly in the left leg with a matrix gel containing Ly6G proteins and lipopolysaccharides, followed by injection of Ly6G NPs in the tail vein (n = 3).
