Abstract
A method for non-invasive detection of a disease, a status of illicit-drug use, or smoking status includes transferring a body fluid obtained from a patient to a sensor comprising a nano-scale surface structure to allow the body fluid to come in contact with the nano-scale surface structure, illuminating the body fluid and the nano-scale surface structure by a laser beam, scattering the laser beam by the body fluid and the nano-scale surface structure to produce a scattered light, and analyzing the scattered light using a spectral analyzer to diagnose a disease, the status of illicit-drug use, or smoking status in the patient.
