The preparation and characterization of sub-micron hydrophilic nanoparticles with an ability to solubilize and release bioactive hydrophobic molecules in a controlled thermoset was reported. Pyrene fluorescence was studied in different nanoparticle concentrations to determine nanostructure. It was observed that the nanoparticle diameters, ranging between 50 and 500 nm, increased with the macromonomer concentration and with decreasing emulsifier content. The absorbance intensity at 490 nm of the nanoparticle suspension was used to calculate the percentage of doxorubicin (DOX) released.
