Infrared spectroscopic determination of drugs in saliva

Abstract

Drugs influence the human body in many ways. Cocaine (COC), for instance, leads impaired drivers to the tendency for speeding, high-risk behaviour and total loss of control [1]. As a consequence an-easy-to-handle on-site test is necessary to diagnose impaired drivers and reduce car crashes related to the influence of drugs. Another example for a drug of interest would be caffeine. There are extended studies that analyze the connection between caffeine and suicidal, maniac and schizophrenic behaviour as well as depressions [2]. For research in this field it would be helpful to monitor the caffeine level with a non-invasive method.
