A method of manufacturing a therapeutic agent for the treatment of infections includes the steps of preparing a homogeneous solution of poly(DL-lactide-co-glycolide acid), preparing a solution of a peroxygen donor, preparing a solution of an acetyl donor, adding each of the solutions to a quantity of the poly(DL-lactide-co-glycolide acid) solution to produce a resultant mixture, preparing encapsulated nano- or micro-scale particles from the resultant mixture using a microencapsulator, collecting the nano- or micro-scale particles, and subsequently subjecting the particles to a lyophilization process.
