Highly Sensitive Detection and Spectral Analysis of Ultraweak Photon Emission from Living Samples of Human Origin for the Measurement of Biomedical Information

Ultraweak photon emission originating from living systems and organisms is generally called biophoton emission and has known to occur naturally in conjunction with various vital processes of life. The aim of our study is to develop new techniques for biomedical measurements and analyses based on highly sensitive detection and characterization of biophoton emission from living samples of human origin. In this paper, we report the fundamental techniques and instrumentation developed newly for the measurement of ultraweak photon emission intensity and its spectral distribution together with basic characteristics of ultraweak photon emission from blood plasma, urine, sputum and breath samples taken from various subjects.
