Summary
This summary is machine-generated.

This study presents a novel paper-based sensor for detecting organophosphate pesticides (OPs). The sensor utilizes a bioenzyme-nanozyme system for sensitive and portable detection of pesticide residues.

Area of Science:

  • Environmental Science
  • Analytical Chemistry
  • Biotechnology

Background:

  • Organophosphate pesticides (OPs) pose significant risks to human health and the environment due to improper usage and residue.
  • Current detection methods often lack the simplicity, portability, and sensitivity required for widespread application.
  • There is a critical need for advanced sensing technologies to monitor OPs effectively.

Purpose of the Study:

  • To develop a simple, portable, and sensitive all-in-one paper-based sensor for organophosphate pesticide detection.
  • To integrate bioenzyme and nanozyme components for enhanced catalytic efficiency in pesticide sensing.
  • To establish a reliable method for on-site detection of pesticide residues in food samples.

Main Methods:

  • Synthesis of a Ce/Zr-MOF@FP (cerium/zirconium-metal-organic framework on filter paper) with peroxidase-like activity.

Key Elements for Plant Nutrition

Like all living organisms, plants require organic and inorganic nutrients to survive, reproduce, grow and maintain homeostasis. To identify nutrients that are essential for plant functioning, researchers have leveraged a technique called hydroponics. In hydroponic culture systems, plants are grown—without soil—in water-based solutions containing nutrients. At least 17 nutrients have been identified as essential elements required by plants. Plants acquire these elements from the...

  • Immobilization of an acetylcholinesterase-cholinesterase-TMB (AChE-ChO-TMB) system onto the Ce/Zr-MOF@FP using gelatin for cascade catalysis.
  • Integration of the sensor with a Python-based image recognition algorithm for quantitative detection of OPs based on enzyme inhibition.

    • Main Results:

    • The developed sensor demonstrated high sensitivity for detecting 2,2-dichlorovinyl dimethyl phosphate (DDVP), a model OP, with a detection limit of 0.32 ng/mL.
    • Excellent recovery rates ranging from 95-107% were achieved, indicating the accuracy and reliability of the sensor.
    • The proximity effect from gelatin immobilization enhanced the cascade catalysis efficiency of the bioenzyme-nanozyme system.

    Conclusions:

    • The all-in-one paper-based sensor offers a promising solution for the rapid, on-site detection of organophosphate pesticide residues.
    • The combined bioenzyme-nanozyme approach provides a sensitive and efficient platform for environmental and food safety monitoring.
    • This technology has significant potential for practical application in detecting DDVP in vegetables and fruits.
