By Xun Shen, Roel van Wijk

It is now good verified that every one residing platforms emit a vulnerable yet everlasting photon flux within the seen and ultraviolet diversity. This biophoton emission is correlated with many, if now not all, organic and physiological services. There are symptoms of a hitherto-overlooked details channel in the residing procedure. Biophotons may perhaps set off chemical reactivity in cells, development keep an eye on, differentiation and intercellular verbal exchange, i.e. organic rhythms. the fundamental experimental and theoretical framework in addition to the technical difficulties and the huge box of purposes within the biotechnical, biomedical engineering, engineering, drugs, pharmacology, environmental technological know-how and uncomplicated technological know-how fields are offered during this booklet. to advertise the conversation and mutual penetration among biophoton examine and photon expertise is among the very important targets for the overseas convention on Biophotons & Biophotonics 2003, and is constructed and awarded in Biophotonics: Optical technological know-how and Engineering within the twenty first Century.

2001), but so far, there is still a lack of conclusive evidence to prove or disprove it. In order to provide a critical test of this swelling theory, we used fluorescence imaging techniques to measure the dynamic re-distribution of GFP-labeled cytochrome c in living HeLa cells, and used a red color fluorescent dye, Mitotracker, to image the morphological change of mitochondria at the same time (Figure 2D). We found that mitochondria did swell when HeLa cells were induced to enter apoptosis by UV treatment.
