Chitosan nanoparticles (CSNPs) have proven their excellent drug delivery potential through various routes of administration and therefore, the need for large scale production of CSNPs for the commercialization is paramount. Their particle size and surface charge, drug loading capacity, and morphology were characterized in this study. Finally, drug release studies of both continuous and scalable modes were undertaken to ascertain suitability of CSNPs as a carrier for HC. The particle size of the large and small scale of HC-CSNPs was 253.3±16.4 nm and 225.4 ±9.6 nm, respectively. Besides, the surface charge of the large and small scale of HC-CSNPs was +35.3±0.3 mV and +32.6±2.5 mV, respectively. The size and surface charge of both HC-CSNPs were not proven to be statistically different. Drug loading capacity of large and small scale production of HC-CSNPs was high with 89%, and 83% of HC was loaded into CSNPs, respectively. Moreover, the morphology of both large and small scale production of HC-CSNPs had a similar shape and particle size. The drug release profile of CSNPs prepared by both methods showed a significantly (p<0.05) higher percentage release as compared to the free form. It is expected that positively charged nano-sized HC-CSNPs with high drug loading capacity could enhance the efficiency of drug delivery system to carry and diffuse into the target cells. The results obtained also suggested that the modified method applied could be further developed for large scale production of HC-CSNPs.
