Fig. 1From: Single-cell RNA sequencing reveals the mechanism of sonodynamic therapy combined with a RAS inhibitor in the setting of hepatocellular carcinomaStructure and characterization of the composite IR820 nanocapsule. a Transmission electron microscopy image showing a quasi-spherical morphology of IR820@NCP with a mean diameter of about 300 nm and high dispersity. Original magnification = ×25,000. Scale bar = 500 nm; b The DLS results showed a mean particle size of IR820@NCP to be 357.8 ± 20.0 nm with a 0.005 polydispersity value; and c The Zeta PALS BI-90 Plus analyzer indicated a surface Zeta potential of IR820@NCP to be − 38.58 ± 0.27 mVBack to article page
