Schematic of air (inner nozzle)–liquid (outer nozzle; Eu/PTX in ethanol) two-phase electrospray (The real setup of the electrospray is shown as inset photograph.) to produce concave (mimicking the shape of blood cells) particles (Eu-FBCP/PTX) from bubble pressing of Eu/PTX melts inside drying droplets under a balance between the electrical (BE) and mechanical (CaRe) parameters for use in chemo-immunotherapy combined with aPL. The similarly sized spherical particles (Eu-s/PTX) were produced using a single-phase (Eu/PTX solution only) electrospray for comparison in the absence and presence of aPL
