Special Issue Information

Dear Colleagues,

Electrochemical sensors and biosensors have gained popularity in recent years, which is linked to the progress of materials, the increasingly refined use of biological components, and their application in analytical methods. The fields of application are diverse, from the study of production processes to food quality, but it is above all the application of electrochemical sensors to the field of human health (in both preventive and diagnostic–therapeutic functions) that promises a real revolution in the coming years. Diagnostic systems integrated in distributed sensor networks find in electrochemical sensors the ideal elements for advanced 'bedside' diagnostics that do not require complex analytical equipment and dedicated laboratories. This is the prediction for the future for advanced societies, but also for developing nations that lack state-of-the-art healthcare services. Territorial medicine and telemedicine will increasingly rely on small, low-cost, easily transportable, and interfaceable precision analytical devices: electrochemical sensors and biosensors are the ideal devices for these applications. Diagnosing infectious diseases or neoplasms, quantifying metabolites, antigens, or antibodies, and validating the presence of specific DNA or RNA sequences are just some of the applications of electrochemical (bio)sensors that have the potential to revolutionise large-scale diagnostics. Designing, characterising, and validating an electrochemical (bio)sensor with relevant and predictable analytical performance is not always easy, and the time-to-market is often very long. Indeed, biological fluids are complex matrices, and sample preparation requires equipment that is not always present in the places where the sensors are used. For a 'real-world' application, i.e., those outside the laboratory, sensors must be able to work on samples that are minimally treated or not treated at all. This Special Issue of Chemosensors brings together original studies or systematic literature reviews representing the state of the art of electrochemical sensors applied to biomedical analysis.

The scope of Chemosensors spans topics concerning the development, characterisation, and application of chemical sensors. Electrochemical sensors and biosensors represent a subset of chemical sensors. The application of electrochemical sensors for the prevention, diagnosis, and treatment of diseases is a field that has undergone extensive development in recent years.

The topics of interest for this Special Issue are as follows:

  • Development and characterisation of electrochemical sensors and biosensors for the detection of molecules of biomedical interest;
  • Application and study of new transducers and/or polymers for electrochemical sensing of molecules of biomedical interest;
  • Nanostructuring of transducers for increasing the performance of electrochemical sensors applied to the study of molecules of biomedical interest;
  • Development/application of electrochemical methods for the analysis of molecules of biomedical interest;
  • Sensors and biosensors for DNA and RNA analysis;
  • Sensors and biosensors for the analysis of small molecules, peptides, and proteins;
  • Immunobiosensors;
  • Interfering signal reduction strategies (biological matrix adaptation);
  • Innovative biological sample pre-processing for reducing electrochemical interferents;
  • Application of electrochemical sensors/biosensors to study analytes in biological fluids;
  • Strategies aimed at increasing the shelf-life of sensors and their application in difficult contexts far from the laboratory (bedside);
  • Development of electrochemical systems for studying multiple analytes from the same biological sample;
  • Development of integrated and/or portable electronic systems to interface with electrochemical sensors for biomedical analysis;
  • Development/integration of electrochemical sensor networks for biomedical and telemedicine applications;
  • Systematic literature review on topics related to current developments/trends in electrochemical sensor technology applied to human health.

Approximately 4% of women of reproductive age are estimated to suffer from premenstrual dysphoric disorder (PMDD), a condition likely underdiagnosed due to various biases, suggesting that actual prevalence may be higher. Addressing this, a novel electrochemical sensor was developed using a screen-printed electrode of reduced graphene oxide modified with a Cu(II) triazole complex, Cu(LNO2)2/rGO/SPCE. This sensor aims to determine levels of serotonin and 17β-estradiol rapidly, and simultaneously, key analytes implicated in PMDD. The method demonstrated high sensitivity for both analytes, achieving sensitivity levels of 0.064 μA/μmol L−1 for serotonin and 0.055 μA/μmol L−1 for 17β-estradiol, with a linear detection range of 2 to 42 μmol L−1. Detection limits were 42 nmol L−1 for serotonin and 53 nmol L−1 for estrogen. The sensor also exhibited high stability and selectivity against common interferents found in biological fluids. It was successfully used to measure serotonin and 17β-estradiol in human serum and urine, with recovery percentages within the expected ranges. This demonstrates that the sensor proposed in this work holds significant potential to contribute not only to the accurate diagnosis of such disorders but also to their treatment. We hope that this research will pave the way for the development of devices that have a positive impact on the quality of life of women suffering from multisystem diseases caused by hormonal malfunctions.
