About this Research Topic
Novel chemical sensors are poised to revolutionize fundamental scientific research and our daily lives, as they play a more and more important role in various areas within clinical diagnosis. Nowadays, several definitions of chemical sensors are widely recognized, among which include miniaturized devices that can deliver real- time and on-line information in the presence of specific compounds or ions in complex samples. They are also defined by IUPAC as devices that transform chemical information, ranging from the concentration of a specific sample component to total composition analysis, into an analytically useful signal. Furthermore, organic chemists consider them to include various synthetic molecular probes, alternatively known as chemosensors.
Chemical sensors form an interdisciplinary field that attracts not only chemists but also engineers with various backgrounds. Whether the approach is problem-oriented in order to tackle meaningful analytical problems, or an extension of a brilliant ideal or methodology, the way to a “perfect” chemical sensor is filled with obstacles that are equally interdisciplinary. The goal of this Research Topic is to emphasize the missing links between sensing concepts and real applications in the biomedical field, such as sensors targeting pH, oxygen, ions, nucleic acids for point-of-care testing, wearable and implantable devices. Indeed, transforming a sensing principle into a ready-to-use product faces challenges arising from various sides, including selectivity, detection limit, response time, sensitivity, reproducibility, portability, cost, etc.
We welcome new concepts and applications related to chemical sensors intended for biomedical use. Topics for individual contributions should be pertinent to the subject of chemical sensors, including but not limited to:
• optical sensors
• electrochemical sensors
• microfluidic devices
• devices for point-of-care testing
• wearable sensors
• functional nanomaterials for the fabrication of chemical sensors
