We apply cutting-edge spectroscopic technologies to explore novel routes to populational health screening. To this end, we extract the electric-field molecular fingerprint of biological samples by measuring the time-dependent electric field of an infrared light wave that is transmitted through a sample. This measurement reveals the time-dependent electric field of the sample itself, which constitutes the "fingerprint" that can be used to analyze the molecular composition of the sample. The electric-field molecular fingerprint responds to changes in the molecular composition of biological samples. Such alterations in human blood serum or plasma are connected to changes in the physiological state of the human organism. This connection serves as a basis for the ability of specific molecular markers (biomarkers) to signal a transition from health to disease. The efficacy of detecting such a transition tends to increase with the use of multiple markers. May the infrared molecular fingerprint—as a multiparametric biomarker—be sensitive to a variety of chronic conditions? This is the question that we seek to answer.
