Assembly of core-shell particles constructed with PLGA nanoparticles (NPs) and PHEA-g-C18 microbubbles (MBs). (a) The scheme to describe the microstructure of the core-shell particles. (b) The confocal microscopy image of FITC-labeled PLGA NPs. (c) The confocal microscopy image of PHEA-g-C18 MBs coated with FITC-labeled PLGA NPs. Red dotted circles represent the MBs. (d) The size growth of plain MBs, termed MBs, and MBs associated with PLGA NPs, termed MBs + PLGA NPs. MBs were prepared with 1% w/w PHEA-g-C18 solution. In (d), the values and error bars of each bar represent average values and standard deviation of more than 50 microbubbles per condition respectively.
