Wang Y, Cui H, Sun C, Zhao X, Cui B - Nanoscale Res Lett (2014)

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.

Mentions: The analyzing results of Abamectin-loading capacity of Abam-PSNs formed at different etching times were shown in FigureĀ 6. The Abamectin-loading capacity was increased from 81.0 to 111.0 mg/g with prolonging etching time from 45 to 120 min. The results indicated that Abamectin-loading capacity of Abam-PSNs can be controlled by adjusting the porosity of PSNs carriers.Figure 5
