“…An ultra-weak photon emission measurement system has been successfully used as a non-invasive tool for monitoring membrane lipid peroxidation in Chlamydomonas [56]. Moreover, the optical detection of responses to salinity and drought stress using a biophoton technique has been documented in red beans [32,33]. The biophoton emission results obtained here imply that less oxidative damage occurred in BABA-primed leaves following Cd stress as compared to nonprimed leaves.…”

“…Measurement of biophoton using photon counter is considered as a non-destructive method of assessing plant condition under stressed environment [31]. The optical detection of salinity and drought stress using biophoton technique has been well documented in red beans [32,33]. Detailed study of hypersensitive responses to cucumber mosaic virus in cowpea has revealed that the stress-induced generation of excess reactive oxygen species (ROS) is involved in photon emission [34].…”

“…In recent times, the accurate detection of individual photons has become increasingly important in medical imaging [2][3][4][5][6][7], biophoton research [8][9][10], high-energy physics and astronomy [11][12][13][14][15][16], and similar fields. Therefore, understanding the wave-particle duality of light and X-rays is an increasing requirement for the students of radiation science.…”

At the quantum-mechanical level, all substances (not merely electromagnetic waves such as light and X-rays) exhibit wave–particle duality. Whereas students of radiation science can easily understand the wave nature of electromagnetic waves, the particle (photon) nature may elude them. Therefore, to assist students in understanding the wave–particle duality of electromagnetic waves, we have developed a photon-counting camera that captures single photons in two-dimensional images. As an image intensifier, this camera has a triple-stacked micro-channel plate (MCP) with an amplification factor of 10(6). The ultra-low light of a single photon entering the camera is first converted to an electron through the photoelectric effect on the photocathode. The electron is intensified by the triple-stacked MCP and then converted to a visible light distribution, which is measured by a high-sensitivity complementary metal oxide semiconductor image sensor. Because it detects individual photons, the photon-counting camera is expected to provide students with a complete understanding of the particle nature of electromagnetic waves. Moreover, it measures ultra-weak light that cannot be detected by ordinary low-sensitivity cameras. Therefore, it is suitable for experimental research on scintillator luminescence, biophoton detection, and similar topics.

Ultraweak photon emission from herbivory-injured maize plants

Following perception of herbivory or infection, plants exhibit a wide range of inducible responses. In this study, we found ultraweak photon emissions from maize leaves damaged by Helicoverpa armigera (Noctuidae). Interestingly, mechanically damaged maize leaves treated with caterpillar regurgitants emitted the same intensity and pattern of photon emissions as those from maize leaves damaged by caterpillars. Furthermore, two-dimensional imaging of the leaf section treated with the oral secretions clearly shows that photon emissions were observed specifically at the lip of the wound exposed to the secretions. These results suggest that the direct interaction between maize leaf cells and chemicals contained in caterpillar regurgitants triggers these photon emissions.
