Characterization of the microfluidic chip and microspheres
(A) Schematic diagram of the microfluidic chip model used here. Cross-sectional schematic diagram of the chip in three views(I–III) and the overall schematic diagram of the chip (IV).
(B) Three views of the microfluidic chip (I–III) and the moment when microspheres exit from the inner phase channel of the chip (IV).
(C) Morphological analysis of GA-MS with different diameters (n = 3, n represents number of GA-MS sample groups). FITC-dyeing GA-MS with the same water-phase flow rate but different oil-phase flow rates (I–V) and FITC-dyeing GA-MS with the same oil-phase flow rate but different water-phase flow rates (III, VI, VII). The statistical diagram of microsphere diameters (VIII).
(D) SEM images of GA-MS that show their dispersed homogeneous morphologies.
