Chemical Sensors for Prostate Cancer Detection Oriented to Non-invasive Approach

Metabolism processes reflect the health state of human body. On this basis it is possible to look at the human body as a biosystem transfer function having as inputs the sources originated from environmental and as outputs the metabolic fluids of the body. The chemical composition of these fluids depends on the specific interactions inside the body. A particular pathological state could modify the chemical fingerprint of some sources like skin emissions, breath, urine. In this work the authors have analysed the fingerprint of patients affected by prostate cancer of urine headspace by means of a gas sensors array. This work follows a pilot study performed on behalf of authors in which a characterization of these patterns has been preliminarily investigated.
