Fig. 4From: Intensity-adjustable pain management with prolonged duration based on phase-transitional nanoparticles-assisted ultrasound imaging-guided nerve blockadeA Cell internalization of HUVEC cells treated with Ce6 doped RLBP nanoparticles and B corresponding quantitative data. The scale bars are 50 μm. C Cell viability assay of the RLBP nanoparticles incubated with HUVEC cells with or without ultrasound irradiation. D Cell viability assay of RLBP nanoparticles-treated HUVEC cells for different times. E Calcein-AM and PI co-staining images of DRG cells treated by RLBP nanoparticles with different ultrasound irradiation intensitiesBack to article page
