Interface‐Adaptive Dual‐Color Hydrogel with Self‐Repairing Function and High Adhesion as Flexible Wearable Sensor for Minimally‐Invasive Monitoring Pesticide Residue in Living Crop

Advanced Science, EarlyView.
Dual‐color hydrogel TPE@Mn@ZnS@AG@PVA is prepared using b‐TPE NPs and r‐Mn@ZnS QDs as blue‐channel and red‐channel indicators, exhibits smart interface adaptability, high adhesion, good self‐repairing function, and superior response to thiophannate‐methyl, and thus acts as a flexible wearable sensor for in situ, on‐site and minimally‐destructive ...

Natural Herbicide Shows Cytotoxicity, Neurotoxicity, and Antioxidant System Alterations on SH-SY5Y and HaCaT Cell Lines

Agrochemicals
Weeds have acquired resistance to commonly used herbicides, and to replace them, new products, including those of natural origin, have been produced. This study evaluated the neurotoxicity, cytotoxicity, and changes in the antioxidant system caused by ...

New Discoveries in Agrochemicals [PDF]

, 2004
Previously, the development of new agrochemicals has begun on the chemist's bench, screened via bioassays, and brought to the marketplace following field trials. Since the evolution of molecular, combinatorial and green chemistry techniques, our approach to new discoveries in agrochemicals has fundamentally changed.

Enzyme Immobilization by Hydrogen‐Bonded Organic Framework for the Construction of Plant‐Wearable Sensor

Advanced Science, EarlyView.
By modulating the charge of acetylcholinesterase, it is encapsulated within HOF materials, thereby enhancing its stability and maintaining its activity. Subsequently, the composite material is embedded in a glycerol‐sodium alginate gel, achieving the long‐term monitoring of pesticides.

Toward Sustainable Pesticide Application: Bridging Efficacy and Food Safety

Advanced Science, EarlyView.
A fully bio‐based lignin coacervate system is developed for pesticide delivery, enhancing leaf retention, UV resistance, adhesion, and wetting. The formulation enables pH/laccase‐triggered release for prolonged action, reduces ecological toxicity, and is fully washable, reconciling agricultural efficacy with food and environmental safety.

Cupin‐Type Dimethylsulfoniopropionate Lyase from Pelagibacter ubique (DddKPu) Catalyzes Aza‐Michael Addition of Primary and Secondary Amines to Acrylic Acid

Angewandte Chemie, EarlyView.
A dimethylsulfoniopropionate lyase (DddK) was identified as an efficient aza‐Michaelase for the addition of amines to acrylate. Screening 74 amines with wild‐type DddK and its W26G variant yielded N‐substituted and N,N‐disubstituted β‐amino acids in 30%–93% isolated yield.

The Trading and Use of Agrochemicals [PDF]

, 2013
The use of synthetic chemicals has revolutionized agriculture, bringing at the same time huge gains in the form of increased food yields and many significant problems arising from the toxic nature of many of the formulations. The global demand for greater quantities and a certain standard of food has continued to encourage agrochemical use at the same ...
