Polypyrrole-Based Nanorobots Powered by Light and Glucose for Pollutant Degradation in Water

Original language description

Novel photo- and enzymatically-active nanomotors were developed for efficient organic pollutant degradation. Light-absorbing polypyrrole nanoparticles were equipped with a bi-enzyme (glucose oxidase/catalase (GOx/Cat)) system enabling the simultaneous utilization of light and glucose as energy sources for jet-induced nanoparticle movement and active radical production. In particular, the GOx utilizes glucose to produce hydrogen peroxide, which is subsequently degraded by Cat, resulting in the generation of active radicals and/or oxygen bubbles that propel the particles. Uneven grafting of GOx/Cat molecules on the nanoparticle surface ensures inhomogeneity of peroxide creation/degradation, providing the nanomotors propelling in random directions. The nanomotors were tested for their ability to degrade a model pollutant, chlorophenol, in various experimental conditions, both with and without simulated sunlight illumination or glucose addition. In all cases, degradation was accelerated by the presence of the self-propelled microparticles or light illumination. Light-induced heating also positively affected enzymatic activity, further accelerating nanomotor diffusion and pollutant degradation. In fact, the chemical- and photoactivity of the nanoparticles led to more than 95 % removal of chlorophenol in 1 h, without any external stirring. Finally, the quality of the purified water and the extent of pollutant removal was checked using a microbiological assay, with significant synergy demonstrated between glucose pumping and sunlight illumination.
