The purpose of this study is to reduce the particle size in micrometer range through a suitable method called Emulsification diffusion Method (EDM). Microparticles offer advantages over bulk particles and macroscale materials due to their higher surface to volume ratio. As biomaterials, microparticles play a crucial role in pharmacological and biomedical research because of their controlled interaction with the biological system. To create micrometer-sized starch particles-which are frequently employed as polymeric carriers-the emulsification-diffusion method (EDM) was employed. Any appropriate medication or API (Active Pharmaceutical Ingredient) ought to be selected. Naproxen Sodium was thus selected as the model medication. Saturating an aqueous phase with stabilizer, emulsifying a drug and polymer solution, and then adding too much water are the steps involved in the preparation process. Research has been done on how process variables affect the average size of microparticles. It was made apparent that the kind and concentrations of stabilizer, the speed at which the magnetic stirrer homogenizes, and the polymer concentration all affected the size of the microparticles. Naproxen Sodium with starch particles smaller than 10 μm was obtained using a Scanning Electron Microscopic (SEM) test. It was discovered that the morphology of the microparticle showed no distinctive changes upon incorporation of drugs or luminosity. Furthermore, because of their large surface area, the medication is integrated into the microcarrier, which increases their effectiveness. The effectiveness of the Emulsification Diffusion Method for enhancing microscale particle size reduction is investigated in the study that is being presented. In support of the particle size data, starch microparticles were found to exhibit a range of 1-10 μm, indicating that the Emulsification Diffusion Method (EDM) is a viable technique for the creation of microcarriers.
