Microcapsules provide a microenvironment by improving the protection and delivery of cells drugs to specific tissue areas, promoting cell integration regeneration. Effective microcapsules must not only be permeable for micronutrient diffusion but mechanically stable. Alginate hydrogel is one commonly used biomaterials fabricating due its gel-forming ability low toxicity. However, mechanical instability, inertness, excessive porosity have impeded use. Embedding nanofibrils in alginate improves their biological properties. In this research, electrospun composite nanofibers PCL–gelatin (PG) were first fabricated, characterized, cryoground. The filtered cryoground powder solution was mixed with through electrospray, fabricated into microcapsules. Parameters such as flow rate, voltage, composition, which are critical electrostatic encapsulation process, optimized. further immersed different solvent environments (DI water, complete media, PBS), observed compared morphology, size distribution, stability average diameters PG ranged between 0.2 2 μm, an 58 73%. varied 300 900 depending on environment. Overall, results showed improved 3D network suitable biomedical applications.
