超弱生物发光--生物光子的发射--仍然是一个实验上已经确定的现象,但理论上知之甚少。本文对生物光子自发发射和延迟发光的物理过程进行了一些相关的研究。由于光强依赖于其相应电场的模量平方,我们首先对各种生物系统内的固有电场作了一些一般性的估计。由于生命物质在初始激发后的光子发射(“延迟发光”)在激发后通常不遵循简单的指数衰减规律,我们从一般理论的角度讨论了这种非指数衰减,并论证了它们通常是预期的以及为什么。然后,我们讨论了一些非线性速率方程背后的动力学,将它们与生物生长速率和生物光子发射速率联系起来,指出了与癌症的可能联系。然后我们回到在实验环境中看到的延迟发光的非指数衰减规律,并再次注意到与癌症的可能联系。

英文摘要:
  Ultraweak bioluminescence - the emission of biophotons - remains an experimentally well-established, but theoretically poorly understood phenomenon. This paper presents several related investigations into the physical process of both spontaneous biophoton emission and delayed luminescence. Since light intensities depend upon the modulus squared of their corresponding electric fields we first make some general estimates about the inherent electric fields within various biological systems. Since photon emission from living matter following an initial excitation ("delayed luminescence") typically does not follow a simple exponential decay law after excitation we discuss such non-exponential decays from a general theoretical perspective and argue that they are often to be expected and why. We then discuss the dynamics behind some nonlinear rate equations, connecting them both to biological growth rates and biophoton emission rates, noting a possible connection with cancer. We then return to non-exponential decay laws seen for delayed luminescence in an experimental context and again note a possible connection with cancer.
