Figure 1

(a) Schematic illustration of the formation of echogenic PPyHMs for combined US imaging and PTT via a facile O/W microemulsion method; SEM and ultrathin-section TEM images of obtained PPyHMs with (b) PVP and (c) PVA as stabilizers; (d) UV-vis-NIR spectra of various concentrations PPyHMs dispersed in RPMI-1640 culture medium, inset was the photograph for various concentrations of PPyHMs dispersed in RPMI-1640 culture medium, indicating good dispersibility; (e) Heating curves of PPyHMs in RPMI-1640 culture medium at different concentrations under 808 nm laser irradiation.
