Abstract
About this talk
Plant enzyme-based biosensors harness enzymes derived from plant sources to catalyze specific biochemical reactions for environmental monitoring and remediation. These biosensors interact selectively with target pollutants including pesticides, synthetic dyes, and industrial chemicals resulting in the generation of measurable signals that enable sensitive detection, even at low concentrations. Beyond detection, plant enzymes can facilitate the transformation of toxic compounds into less harmful or non-toxic byproducts, thereby contributing directly to bioremediation of contaminated environments.
Compared to conventional chemical monitoring approaches, which often rely on harsh reagents and generate secondary pollution, plant enzyme-based biosensors offer a sustainable and environmentally benign alternative. Plant enzymes are naturally abundant, biodegradable, and highly specific, aligning well with green chemistry principles and sustainable environmental practices. This presentation explores the development, design principles, and applications of plant enzyme–based biosensors in environmental monitoring. Future research directions and technological advancements are highlighted, underscoring the potential of plant enzyme-based biosensors as effective tools for addressing pressing environmental challenges and advancing environmental sustainability.
