    The use of aptamers for environmental biosensors
    (Elsevier, 2024) Özyurt, Canan; Ince, Bahar; Uludağ, Inci; Sezgintürk, Mustafa Kemal
    In recent years, the development of innovative technologies has revolutionized the field of biosensing, offering new possibilities to detect and monitor environmental pollutants with unique sensitivity and specificity. Environmental biosensors have become crucial tools in addressing the growing concerns about pollution, contamination, and the overall health of our ecosystems. These biosensors play a significant role in detecting and monitoring various pollutants, including organic pollutants, heavy metals, pathogens, and endocrine-disrupting chemicals. Recent developments in biosensing technologies have led to the emergence of electrochemical aptasensors as a promising approach to detecting and monitoring environmental pollutants. Aptasensors, which utilize aptamers as biorecognition elements, offer numerous advantages over traditional analytical techniques. These advantages include high sensitivity, rapid response, low cost, and compatibility with portable and miniature devices. By combining the unique properties of aptamers with the sensitivity and simplicity of electrochemical sensing, aptasensors have the potential to revolutionize environmental monitoring. This chapter primarily focuses on using electrochemical aptasensors to detect and analyze environmental pollutants within the past 3 years. This work aims to serve as a valuable resource for future research endeavors by comprehensively examining various design methodologies’ analytical and technical intricacies with merits and drawbacks. © 2024 Elsevier Inc.
