A first step to develop quantum medicine: Radiometers, detectors, and biosensors

Radiometers and Wearable biosensors, as vital parts of the realm of quantum medicine, are becoming popular for their ability to continuously and immediately provide physiological data through single-cell spectroscopy, brain imaging, and noninvasive monitoring of biochemical markers in various neuroimaging and biofluids such as sweat, tears, and interstitial fluid. Various biosensing, microfluidic sampling, and transport technologies have been combined, made smaller, and incorporated with flexible materials to improve ease of use and comfort. Enhancing the understanding of the connections between noninvasive biofluids and blood analyte levels is crucial for improving the reliability of wearable biosensors. This review discusses the noninvasive monitoring of biomarkers such as hormones and metabolites utilizing electrochemical and optical biosensors, single-cell spectroscopy, and brain imaging. Increasing the number of biomarkers for monitoring will need further on-body bio affinity testing and various sensing devices. Large-scale validation studies with many participants are necessary to use wearable biosensors in therapeutic settings. Wearable biosensor technology's ability to quickly and accurately detect real-time physiological data in therapy might significantly impact our daily routines
