Preparation and Size Control of Efficient and Safe Nanopesticides by Anodic Aluminum Oxide Templates-Assisted Method

Abstract

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.

Utilization of marine gypsum as an alternative to mineral gypsum in the reclamation of degraded sodic soil and as a means of enhancing crop productivity

“…The results are in conformity with the earlier findings (Bolan et al, 1991; Keren & Shainberg, 1981). As per the Noyes–Whitney equation, the total effective surface area of particles gets increased when particle size is reduced, which results in an enhanced dissolution rate (Wang et al, 2021). Moreover, particle size reduction reduces the thickness of the diffusion layer surrounding MG particle and increases the concentration gradient.…”

A Review on Template Synthesis of Nanoparticle

“…The size and shape of the sample particle are directly determined by the hard template, which is a rigid material with a fixed structure. By using a cooperative assembly between the surfactant and inorganic species, the hard-template approach is an effective way to create Mesoporous materials that are challenging to synthesize by conventional methods [33]. The idea is extremely straightforward and was first put forward by Ryoo et al and Hyeon and coworkers.…”

“…Especially in many synthetic processes and in several natural processes, biopolymers as well as their colloids can serve as templates and regulating agents [83]. The idea of employing biological substances as soft templates is quite intriguing, and a great deal of work has been done to use biological materials with regulated properties that are easily obtainable and economically priced.…”

Preparation, Characterization, and Evaluation of Pyraclostrobin Nanocapsules by In Situ Polymerization

“…The other encompasses green pesticide formulations, such as water emulsions (EWs), water-suspending agents (SCs), microemulsions (MEs), suspension emulsions (SEs), and water-dispersible granules (WDGs) [ 2 ]. However, some pesticide formulations have limitations such as a large particle size, low effective utilization rate, poor dispersion, and inconvenient transportation for practical applications [ 3 , 4 , 5 ]. Studies in recent years have shown that 90% of pesticides are not used effectively in the application process, posing a threat to the environment, and increasing application costs for farmers [ 6 ].…”
