Auricularia auricula biochar supported γ-FeOOH nanoarrays for electrostatic self-assembly and pH-responsive controlled release of herbicide and fertilizer

Recent advances in the design of controlled- and sustained-release micro/nanocarriers of pesticide

“…47 For the management of harmful organisms, controlled- and sustained-release micro/nanocarriers based on stimuli-responsive characteristics provide greater utilization efficiency and reduce the applied amount of pesticides. 16…”

“…12,61 On the other hand, pH-responsive compounds can accept or donate protons at pathological pH, and thereby undergo moderate conformational changes. 14,16 Thus, it is possible to control the release of pesticides from carriers by using the pH change produced by the target organism being infected. 62…”

“…14 The controlled release characteristic of the carriers is based on stimuli-responsive triggers. The physicochemical characteristics of the stimuli-responsive triggers change dramatically when the environment or biological factor changes including light, 15 temperature, pH, 16,17 enzymes, 18 redox, 19 etc. , thus achieving controlled release of the AIs.…”

Recovery of syringic acid from aqueous solution by magnetic Fe–Zn/ZIF and its slow release from the CA-coated carrier based on the 3Rs concept

“…1 However, the improper and excessive use of these substances has caused severe environmental pollution and economic waste. 2 Based on environment-friendly principles, it is essential to develop suitable nanomaterials to recover these pollutants from the environment and control their release into the soil. 3,4 Recently, magnetic sorbents have been extensively exploited due to their easy reusability using an external magnetic field.…”
