Fig. 5From: Enhanced detection with spectral imaging fluorescence microscopy reveals tissue- and cell-type-specific compartmentalization of surface-modified polystyrene nanoparticlesAccumulation of polystyrene nanoparticles in the liver. Traditional fluorescence microscopic images of sections made from livers of non-treated (a) and NP-injected (b, c, d) adult mice. Animals were sacrificed 5 min (b) and 4 days (c) after intravenous injection of PS-COOH and 4 days after injection of PS-PEG (d) polystyrene nanoparticles. Particle fluorescence is shown in green, and bisbenzimide nuclear staining in blue. Scale bars 100 µmBack to article page
