Abstract:
The main objective of this project was to formulate novelamphiphilic PLGA nanoparticles having better physicochemical properties for the delivery of the novel peptide (CK-10) to the cancerous/tumour tissue. Double emulsion/Solvent evaporation [DE/SE] and a novel microfluidic techniques were used to formulate the nanoparticles. Size & images were characterized by laser obscuration time whereas invitro release were measured by modified Lowry assay. Stability was checked by high performance liquid chromatography and capillary zone electrophoresis. Evaluation of the compatibility, interaction and shelf life stability were confirmed by FTIR and differential scanning calorimeter. Water absorption and its associated changes in the physicochemical properties were measured by various color indicator and potentiometric titrations techniques. PLGA/Poloxamer & PLGA/βCyclodextrin nanoparticles produced by the novel microfluidic technique showed the highest in-vitro release with good size criteria and optimum biodegradation for the CK10 delivery to the cancer cells. Better physicochemical properties for the CK-10 loaded PLGA nanoparticles could be obtained by using the novel microfluidic technique to improve the RAN blocking by CK-10.
