We have developed multi-functional nanoparticles and thin-films comprised of a poly(lactic acid) (PLA) core that are surface-decorated with reactive functionality suitable for the capture of malodorous volatile organic compounds (VOCs) associated with rendering cooking vapors.  We have developed six unique formulations that have been fully characterized by 1H NMR, IR, and TGA analysis.  Further, we have demonstrated the ability of the materials to sequester hexanal, a prototypical volatile malodorous VOC, from aqueous solutions and in the gas phase. Finally, the nanomaterials were found to be completely non-toxic in concentrations up to 5000 ppm in a Daphnia magna (water flea) acute toxicity assay.
