摘要：

It is challenging to fabricate uniform starch microspheres (SMs) with sub-10 μm diameters in starch-polyethylene glycol (PEG) aqueous two-phase system (ATPS). To address this issue, a refined approach using starch-polyvinylpyrrolidone (PVP) ATPS is presented in this work. Phase diagrams were constructed for ATPSs containing PVPs of varying molecular weights, which provided crucial insights into the influence of PVP on SM formation. The results revealed that increasing both the molecular weight and concentration of PVP led to higher starch and ...
