  1. Fixed chitosan and TH precursor concentration was designated at 0.1 w/v% and 0.02 w/v%, respectively. 0.075 L/min and 70 °C were picked up as the flow rate of air and inlet temperature (Tc), respectively. σg describes the size dispersion of TH/Chitosan-TPP particles relative to their geometric mean values. Averaged standard deviation of mean size from overall data (not shown) is 45 (nm) with N > 300.
