Microphotographs of the agarose gel with introduced nanodroplets (1 vol % PFP encapsulated into 0.25% PEG-PLLA) before (a) and after (b) sonication by the ultrasound with a frequency of 90 kHz. The agarose gel is used here as a model of the tumor interstitium, the viscosity of which considerably exceeds the blood viscosity.
