Abstract
The objective of this study was to optimize the particle size and encapsulation efficiency of chitosan nanoparticles loaded with 5-Fluorouracil (5-FU) by response surface methodology. Nanoparticles were prepared by ionic gelation method from chitosan and penta sodium triphosphate (TPP) at different combinations of chitosan viscosity, chitosan concentration and chitosan/TPP mass ratio according to the Box-Behnken experimental design. The particle size and encapsulation efficiency of prepared particles were measured by dynamic light scattering and UV spectroscopy, respectively, and the obtained data were subjected to multiple linear regression analysis followed by multi-attribute utility analysis to obtain a model for prediction of the optimum response. The optimum conditions for the production of 5-FU loaded chitosan nanoparticles were found to be low viscosity chitosan 0.5-1 mg/mL, middle viscosity chitosan 0.5-0.8 mg/mL and high viscosity chitosan 0.5-0.75 mg/mL and chitosan/TPP mass ratio of 4 or 6, yielding nanoparticles at the average diameter range of 114-188 nm and encapsulation efficiencies between 42-55%.

Emerging Nanotherapeutics for Mitigation of Neurodegenerative Disorders
Conditions affecting the central nervous system (CNS) present a significant hurdle due to limited access of both treatments and diagnostic tools for the brain. The blood-brain barrier (BBB) acts as a barrier, restricting the passage of molecules from the bloodstream into the brain. The most formidable challenge facing scientists is ...read more
Nanotechnology Based Chemotherapy for the treatment of Head & Neck Cancer
The escalating recurrence rates observed in Head and Neck cancer, particularly within the chemo-therapeutically treated cohort (50-60%), can be attributed to the non-selective nature of current anticancer drug delivery modalities. In this context, nanotechnology-based drug delivery systems emerge as a promising avenue for achieving precise localization of therapeutic agents to ...read more
