Abstract
The detection of 17β-estradiol (E2), a potent endocrine-disrupting compound, is critical for both environmental monitoring and biomedical diagnostics. Traditional detection methods often suffer from limitations in sensitivity, selectivity, and cost-effectiveness. Aptasensors, which utilize aptamers as biorecognition elements, offer promising alternatives because of their high specificity, stability, and adaptability. This paper explores recent advancements in aptasensor technologies for E2 detection, highlighting optical, electrochemical, and surface-enhanced Raman scattering (SERS)-based platforms. The integration of nanomaterials such as gold nanoparticles, carbon dots, and conductive polymers significantly enhances sensor performance, achieving ultralow detection limits and broad dynamic ranges. By leveraging these innovations, aptasensors provide scalable solutions for real-time monitoring of E2 in environmental, food, and clinical samples, paving the way for improved endocrine regulation and public health safety.
期刊介绍：
The Official Journal of the International Federation of Clinical Chemistry and Laboratory Medicine (IFCC)
Clinica Chimica Acta is a high-quality journal which publishes original Research Communications in the field of clinical chemistry and laboratory medicine, defined as the diagnostic application of chemistry, biochemistry, immunochemistry, biochemical aspects of hematology, toxicology, and molecular biology to the study of human disease in body fluids and cells.
The objective of the journal is to publish novel information leading to a better understanding of biological mechanisms of human diseases, their prevention, diagnosis, and patient management. Reports of an applied clinical character are also welcome. Papers concerned with normal metabolic processes or with constituents of normal cells or body fluids, such as reports of experimental or clinical studies in animals, are only considered when they are clearly and directly relevant to human disease. Evaluation of commercial products have a low priority for publication, unless they are novel or represent a technological breakthrough. Studies dealing with effects of drugs and natural products and studies dealing with the redox status in various diseases are not within the journal''s scope. Development and evaluation of novel analytical methodologies where applicable to diagnostic clinical chemistry and laboratory medicine, including point-of-care testing, and topics on laboratory management and informatics will also be considered. Studies focused on emerging diagnostic technologies and (big) data analysis procedures including digitalization, mobile Health, and artificial Intelligence applied to Laboratory Medicine are also of interest.
