Modeled structure of DDT and mosquito retroposon-specific monoclonal antibody (MAb) loaded nanoparticles. The figure shows a theoretical structure of DDT and MAbRST loaded nanoparticles. Note that the model assumes one molecule of ingredient, although that may not be the case. The green colored formula represents a single DDT molecule whose single chain chloride ion interacts with the hydroxyls present in the lactic chain of the polyester of poly (lactic-co-glycolic acid)  commonly used to synthesize nanoparticles. The red formula bracketed × represents lactic acid, while the blue bracketed Y represents glycolic acid. Notice the availability of the hydroxyl (-OH) and free hydrogen (+H) ions at the lactic and glycolic extremities of the PLGA molecule respectively. This possibly accounts for the generality of PLGA as a solvent. MAbRST stands for monoclonal antibodies specific for a mosquito retroposon.
