- W3020851932 abstract "As the population of the world grows, the demand for food and other agricultural resources has led to escalation of pesticide poisoning and environmental hazards. Thus, an efficient system of pesticide detection is a constant endeavor, and a number of technologies are working hand in hand to generate effective biosensors for various classes of pesticides. Many commercial biosensors for detection of pesticides are available based on amperometric or fluorescence detection. Yet more innovative technologies are being developed which overcome issues by reducing time and costs involved in sample preparation. In addition to that, improvements in ease of operation with minimum expertise and better sensitivity have been achieved using various techniques such as optical, colorimetric, fluorescence, chemiluminescence, photoluminescence, SERS, and electrochemical. The essential characteristics of biosensors include limit of detection (LOD) and recovery. A number of tools such as aptamers, gold nanoparticles, quantum dots, molecularly imprinted polymers, bispecific antibodies, etc. are used to develop hybrid biosensors where the sensitivity is increased several folds and limit of detection is as low as 0.1 pM. The time of detection is reduced to 22 min along with simultaneous detection of increasing number of pesticides by the biosensors. Thus, integration of more than one technique overcomes the limitation encountered by one, leading to increased sensitivity, high precision, and broadened applications in pesticide detection. Also, the goal is to accelerate the path toward commercial implementation with point-of-care setting which has the added advantage of cheaper, portable, and handy biosensing technology with much stable recognition element or substrate, which can stay useful and active even at environmental conditions for in-field analysis. Thus, the review encompasses all the above innovations and criteria in detailed and up-to-date analysis." @default.
