Novel fabrication of a yeast biochar-based photothermal-responsive platform for controlled imidacloprid release.

ABSTRACT: For improving the utilization efficiency of pesticides, we developed a novel pesticide delivery particle (YINCP@EC) with a core-shell structure based on yeast biochar, imidacloprid (IMI), ammonium bicarbonate (NH₄HCO₃), calcium alginate (CA), and ethyl cellulose (EC). Therein, yeast biochar, IMI and NH₄HCO₃ were absorbed in the network-structured of CA to obtain YINCP through hydrogen bonds. The resulting composite was granulated using an ion gelation technique and then coated with EC to form YINCP@EC. In this platform, yeast biochar serving as a photothermal agent can efficiently convert sunlight energy into thermal energy, thereby triggering NH₄HCO₃ decomposition into CO₂ and NH₃ that can break throug
