Development of Aerosolizable mRNA Incorporated Chitosan Nanoparticles for Efficient Lung Delivery
… CS-TPP nanoparticles were produced through the Ionotropic gelation method using two different formulation approaches, with one approach containing Incremental concentrations of chitosan and the other in which chitosan and mRNA are mixed as per their weight ratios. The nanoparticles were then …
