Description

One of the major pollutants in the milieu consists of heavy metals that remain nondegradable with extreme toxicity that accumulates in plants, animals, and humans leading to ill effects with long exposures. These heavy metals that are used in various fields like food, textile industries, agriculture, and medicine act as enzyme inhibitors not allowing the substrate to bind the enzymes. In lieu of it, biosensors have been an essential tool that help to monitor environmental pollutants, presence of various toxins and biohazardous microbial in the organic matter, and also biomolecules in diagnostic tools. Detection of heavy metal traces in environmental monitoring has a widespread application using biosensors with improvised sensitivity, selectivity, and simplicity. Further, the biosensor technology has advanced greatly with the ability of biosensing mechanism combined with the highly advanced technique with the world of nanofabricating enabled miniature biosensors. The sensitivity performance of biosensors has increased tremendously with nanotechnology as the nanoscale dimensions promote the critical analysis and detect to probe single biomolecules. Nevertheless, the major drawback relies on the study lacking the toxicity of nanoparticles (NPs) in atmosphere, lacking in automated service, miniature induced unreliable source, and integrating the nano-biosensors for reliable transduction signals from the devices. With the development of biosensors for online and offline analysis for their quantity and diversity they have been termed as biosensor uprising with the introduction of biosensors with enzyme, DNA-, immuno-, and whole cell-based with specific analytical detection. 2024 Elsevier Inc.
