Abstract Natural biopolymers are the most likely choice for biomedical applications, and starches can be considered best materials such applications. This comes from fact of their natural origin high biodegradable behavior. Native have weak hydrogen bonding a leaching behavior – making it candidate drug delivery application. Still, to make starch useful as carrier, this must strengthened. In work, native sweet potato was used, between molecules enhanced by introducing glycerol source sodium alginate (SA) thickener. blend tested means FTIR DSC, based on test results, improved had taken place. Furthermore, microspheres were successfully produced at different flow rates. microfluidic capillary device harnessed form microsphere generating total rates ranging (0.00031 0.00054) cm 3 /sec. Herein, starch/sodium alginate/glycerol mixture used dispersed phase PVA+tween 80 continuous phase. At (0.00062-0.00054) /sec, took an oval shape. (0.00034-0.00048) spherical very low rate (0.00031) shell caused core oozing. formed with diameter (151-263) µm.
