• rate was 50 m3/h, only few microbubbles were generated, thus yielding ZnO/PAN nanofibers with uniform ZnO nanoparticle distribution. In addition, the influence of the spinning voltage on the EMAI processes as well as the quality and yield of ZnO/PAN nanofibers were investigated experimentally and

In both cases, the shells can be custom-made to enhance stability, circulation duration, drug-loading capacity and release rate, targeting the fusion with cell membranes [24]. Both types of constructs are generally more stable, but less echogenic than “true” gas microbubbles

The bubble formation occurs at the solvent–nanoparticle interface. The absorbed photon energy by the nanoparticle is dissipated as heat to the surrounding solvent

Suction also depends on the surface energy of the substrate, as no negative pressures were found on non-wettable
