Advanced intelligent systems for delivery of pesticides or fertilizers require formulations that allow for long-term efficacy. In this work, a metal–organic framework (MOF) hybrid was developed for long-term pest management and micronutrient supply. Zeolitic imidazolate framework-8 was fabricated for crop micronutrients (Zn2+) supply and insecticide dinotefuran (DNF) encapsulation. Polymethylmethacrylate was polymerized in situto impart the MOF hybrid with sustained cargo delivery. Then, zein was introduced to facilitate protease-triggered cargo release associated with the microenvironment of pests and targeted release. The resulting MOF hybrid exhibited stimulus-responsive, slow-release behaviors. Sustained DNF delivery was achieved over a period of at least 32 days in soil. Compared with that of free DNF, the UV resistance of DNF in the MOF hybrid increased by nearly 10 times, and the insecticidal efficiency increased 33.3% with leaching treatment and 40.1% after incubating in a greenhouse for 14 days. This MOF hybrid provides a controlled, targeted, and sustained delivery formulation for long-term pest management and crop micronutrient supply and has huge application prospects in sustainable agriculture.

The arrival of the era of artificial intelligence is constantly advancing the development of flexible electronic materials. However, low mechanical properties, nonflexible signal transmission, and insensitive signal output have restricted their development as sensors. In this study, a superstretching MXene composite conductive hydrogel was developed with a tensile strain of more than 1800%. The hydrogel was used as a flexible wearable sensor to detect human motion signals in real time. High sensitivity was achieved using the sensor to discern multidirectional human motions, such as bending of human joints, throat vocalization, swallowing, and pulse beat. In addition, rapid resilience was observed for the MXene composite hydrogel after unloading reverse compressive stress, which can quickly cause a specific current response in the micropressure area without leaving any traces. This thixotropic sensor achieves a rapid response to bidirectional stress and has huge application prospects in the field of human body motion detection and national defense information encryption.
