a Light microscope images of drug precipitation process in the droplets generated by co-flow microfluidics. b, c Scanning electron microscope images of microspheres prepared by droplet microfluidics, using AcDX (b) and PLGA (c) as carrier matrix. d, e Drug loading degree (d) and encapsulation efficiency (e) of microspheres prepared with and without dimethyl sulfoxide in the inner fluid (n = 3). Data are presented as mean values ± SD. f, g X-ray powder diffractogram (f) and differential scanning calorimetry curves (g) show the solid-state of the encapsulated drug molecules in microspheres.
