WebbThis multiple emulsion microfluidic method results in PLGA droplets containing multiple API loaded water droplets. The PLGA droplets are then dried following a solvent extraction process. During this step, the primary API water droplets remain intact in size and quantity. The encapsulation yield resulting from this process typically exceeds 90%. Webba carboxylic acid group, at its terminal ends. The carboxylic acid end can be easily conjugated to a primary amine group via an amide linkage [20]. In the present study, PLGA was first esterified with NHS by using DCC to activate the carboxyl terminal of PLGA, and then conjugated to the primary amine of PEI. The PEIusedwaslineartypehavingtwo–NH
