Pyridoxal 5'-phosphate (PLP)-crosslinked chitosan nanogels for pH-responsive pesticide release and enhanced foliar delivery.
Conventional pesticide formulations suffer from poor targeting and low active ingredient utilization due to their inability to respond to microenvironmental signals at pest feeding sites. Here, we developed pH-responsive nanogels by crosslinking chitosan with PLP via Schiff base formation and electrostatic interactions...
