Bottom Line: Photolysis and poor solubility in water of Abamectin are key issues to be addressed, which causes low bioavailability and residual pollution.In this study, a novel hydrophilic delivery system through loading Abamectin with porous silica nanoparticles (Abam-PSNs) was developed in order to improve the chemical stability, dispersity, and the controlled release of Abamectin.These results suggest that Abam-PSNs can significantly improve the performance of controllable release, photostability, and water solubility of Abamectin by changing the porous structure of silica nanoparticles, which is favorable to improve the bioavailability and reduce the residues of pesticides.

Fig8: The response curve of the photolysis rate of pure and loaded Abamectin by Abam-PSNs to UV irradiation time.

Mentions: The photolytic rate of Abamectin was estimated by artificial irradiation under UV light. The response curve of the photolysis rate of Abamectin to irradiation time was shown in FigureĀ 8. The photolytic percentage of the Abamectin was 1.4% and 26%, respectively, for the Abam-PSNs and the pure Abamectin after 12 h, while reached 22.5% and 77%, respectively, after 72 h. The results of UV irradiation confirmed that the Abam-PSNs can significantly prevent the photolysis of Abamectin, resulting from the protective effect of the silica carrier.Figure 8
