Thereafter the mixture was subjected to continuous overnight stirring using a magnetic stirrer which ensures the removal of the organic solvent. Further it was subjected to centrifugation at 3000 rpm for 10 minutes at a temperature of 4º C to separate any free unencapsulated drug. Key parameters like surfactant concentration, stirring speed and temperature plays an important role in the successful formation and stability of nanoparticle. The method is easily scalable, making it suitable for industrial application.
