Emerging materials integrated into high performance flexible electronics to detect environmental contaminants have received extensive attention worldwide. The accurate detection of widespread organophosphorus (OP) compounds in the environment is crucial due to their high toxicity even at low concentrations, which leads to acute health concerns. Therefore, developing rapid, highly sensitive, reliable, and facile analytical sensing techniques is necessary to monitor environmental, ecological, and food safety risks. Although enzyme-based sensors have better sensitivity, their practical usage is hindered due to their low specificity and stability. Therefore, among various detection methods of OP compounds, this review article focuses on the progress made in the development of enzyme-free electrochemical sensors as an effective nostrum. Further, the novel materials used in these sensors and their properties, synthesis methodologies, sensing strategies, analytical methods, detection limits, and stability are discussed. Finally, this article summarizes potential avenues for future prospective electrochemical sensors and the current challenges of enhancing the performance, stability, and shelf life.

In sensor applications, the introduction of CNTs onto sensing substrates currently entails intricate processes with concerns over stability. This study demonstrate the utilization of CNT aerogel electrode as an ultrasensitive platform. Further introducing a novel approach employing a cast and pull-back technique along with drop-casting for successful binder less deposition of CNTs onto sensing substrates, utilizing a CNT aerogel film to augment the sensitivity of conventional glassy carbon electrodes (GCEs), screen-printed electrodes (SPEs), and interdigitated electrodes (IDEs). Scanning electron microscopy validates the deposition of CNT forests on GCE, entangled CNT networks on SPE, and IDE. Comparative electrochemical analyses reveal superior performance of CNT-incorporated SPE and GCE sensors, with the CNT aerogel electrode standing out prominently. Notably, CNT-incorporated SPE and GCE sensors demonstrate a respective approximately 12- and 2-fold increase in electrochemical active surface area, whereas the CNT aerogel electrode displays remarkable ~ 40-fold enhancement. For IDE, a significant 1700-fold change in resistance of IDE-CNT in the presence of a redox solution surpasses the 200-fold change observed in bare IDE, underscoring a substantial sensitivity enhancement facilitated by CNT incorporation. The mechanical integrity of CNT aerogel electrode post-exposure to liquids and sonication attests to its robust nature. The preservation of the deposited CNT forest on the SPE and GCE sensor platforms after multiple measurements further underscores its stability. This study positions the CNT aerogel electrode as a resilient and highly sensitive platform, particularly well-suited for the transfer of CNT networks onto diverse sensing substrates, thereby showcasing its potential to advance biomedical sensor technology.

Food security is a global issue, since it is closely related to human health. Antibiotics play a significant role in animal husbandry owing to their desirable broad-spectrum antibacterial activity. However, irrational use of antibiotics has caused serious environmental pollution and food safety problems; thus, the on-site detection of antibiotics is in high demand in environmental analysis and food safety assessment. Aptamer-based sensors are simple to use, accurate, inexpensive, selective, and are suitable for detecting antibiotics for environmental and food safety analysis. This review summarizes the recent advances in aptamer-based electrochemical, fluorescent, and colorimetric sensors for antibiotics detection. The review focuses on the detection principles of different aptamer sensors and recent achievements in developing electrochemical, fluorescent, and colorimetric aptamer sensors. The advantages and disadvantages of different sensors, current challenges, and future trends of aptamer-based sensors are also discussed.
