Introduction
I´m interested in biological autoluminescence also called ultra-weak photon emission. I´m focusing on experimental procedures and data analysis.

Article
Full-text available
Biological systems manifest continuous weak autoluminescence, which is present even in the absence of external stimuli. Since this autoluminescence arises from internal metabolic and physiological processes, several works suggested that it could carry information in the time series of the detected photon counts. However, there is little experimenta...

Photonic signals are broadly exploited in communication and sensing and they typically exhibit Poisson-like statistics. In a common scenario where the intensity of the photonic signals is low and one needs to remove a nonstationary trend of the signals for any further analysis, one faces an obstacle: due to the dependence between the mean and varia...
Article
Oxidative processes present across all types of organisms, including humans, cause chemical formation of electron excited species with subsequent endogenous ultra-weak photon emission. Thus, imaging of this endogenous chemiluminescence using ultra-sensitive devices potentially enables label-free monitoring of oxidative stress in optically accessibl...
Article
Ultra-weak photon emission (UPE) is an endogenous bioluminescence phenomenon present in all biological samples with an active oxidative metabolism, even without an external pre-illumination. To verify the potential of UPE for non-invasive monitoring of metabolism and growth in germinating plants, the aim of this study was to investigate the UPE fro...
Article
Biological samples continuously emit ultra-weak photon emission (UPE, or "biophotons") which stems from electronic excited states generated chemically during oxidative metabolism and stress. Thus, UPE can potentially serve as a method for non-invasive diagnostics of oxidative processes or, if discovered, also of other processes capable of electron...
Article
Full-text available
In this mini-review, we summarize the current hypotheses, theories and experimental evidence concerning the electromagnetic activity of living cells. We systematically classify the bio-electromagnetic phenomena in terms of frequency and we assess their general acceptance in scientific community. We show that the electromagnetic activity of cells is...
Article
Full-text available
Optical spectral analysis of the ultra-weak photon emission (UPE) could be utilized for non-invasive diagnostic of state of biological systems and for elucidation of underlying mechanisms of UPE generation. Optical spectra of UPE from differentiated HL-60 cells and yeast cells (Saccharomyces cerevisiae) were investigated. Induced photon emission of...
Article
The ultra-weak photon emission (UPE) is a universal phenomenon common to all cells with active oxidative metabolism. Generally accepted mechanism of the origin of the ultra-weak photon emission considers reactions of radical or nonradical reactive oxygen species (ROS) with biomolecules such as lipids and proteins which lead to the formation of elec...
Conference Paper
Full-text available
The paper deals with a measurement of the spontaneous ultra-weak photon emission from wild type cells of yeast Saccharomyces cerevisiae during their growth. The objective of the work was to obtain a temporal development of optical signals from yeast samples utilizing two photomultiplier tubes with different properties.
Article
This paper introduces the basic concept of measuring spontaneous ultra weak photon emission from yeast Saccharomyces cerevisiae. The objective of the work is a comparison of ultra weak photon emission from two mitochondrial mutants which differ in an activity of their energy-generatingpathway. Photon emission has been measured in a visible range ut...
