Summary
Researchers developed enzyme-responsive fluorescent nanopesticides using abamectin, protein, and gum arabic. These eco-friendly nanoparticles offer targeted delivery and effective pest control with reduced toxicity for sustainable agriculture.
Area of Science:
- Agricultural Science
- Nanotechnology
- Biochemistry
Background:
- Developing targeted and less toxic pesticide formulations is crucial for sustainable agriculture.
- Current formulations often lack precision and can harm non-target organisms.
- Nanotechnology offers a promising avenue for advanced pesticide delivery systems.
Purpose of the Study:
- To create a novel enzyme-responsive fluorescent nanopesticide formulation.
- To evaluate the properties and efficacy of the developed nanopesticides.
- To demonstrate the potential for sustainable plant protection.
Main Methods:
- A continuous nanoprecipitation method was employed.
- Abamectin, fluorescein isothiocyanate (FITC)-modified protein, and gum arabic were used.
- Enzyme-responsive release was triggered by trypsin.
Main Results:
- The nanopesticides (ABM@BSA-FITC/GA NPs) showed good water dispersibility, stability, and wettability.
- Fluorescence tracking enabled precise monitoring of deposition, distribution, and transport in plants.
- High control efficacy against Plutella xylostella L. was achieved, comparable to commercial formulations.
Conclusions:
- The developed enzyme-responsive fluorescent nanopesticides are effective and eco-friendly.
- This formulation offers a sustainable approach to plant protection with targeted delivery.
- The absence of organic solvents enhances its environmental profile.
