Efficient and safe nanopesticides play an important role in pest control due to enhancing target efficiency and reducing undesirable side effects, which has become a hot spot in pesticide formulation research. However, the preparation methods of nanopesticides are facing critical challenges including low productivity, uneven particle size and batch differences. Here, we successfully developed a novel, versatile and tunable strategy for preparing buprofezin nanoparticles with tunable size via anodic aluminum oxide (AAO) template-assisted method, which exhibited better reproducibility and homogeneity comparing with the traditional method. The storage stability of nanoparticles at different temperatures was evaluated, and the release properties were also determined to evaluate the performance of nanoparticles. Moreover, the present method is further demonstrated to be easily applicable for insoluble drugs and be extended for the study of the physicochemical properties of drug particles with different sizes.

ABSTRACTAnodic aluminum oxide (AAO) membranes were fabricated in a mild two-step anodization procedure. The voltage was varied during both anodization steps to control the pore size and morphology of the AAO membranes. Pore sizes ranged from 34 nm to 117 nm. Characterization of the pore structure was performed by scanning electron microscopy (SEM). To assess the potential of the AAO membranes as a neuronal differentiation platform, C17.2 neural stem cells (NSCs), an immortalized and multipotent cell line, were used. The NSCs were forced to differentiate via serum-withdrawal. Cellular growth was characterized by immunocytochemistry (ICC) and SEM. ImageJ software was used to obtain phenotypic cell counts and neurite outgrowth lengths. Results indicate a highly tunable correlation between AAO nanopore sizes and differentiated cell populations. By selecting AAO membranes with specific pore size ranges, control of neuronal network density and neurite outgrowth length was achieved.
