Optically functionalized biomorphism of bean seeds
Cannellini-Lingot beans (Phaseolus vulgaris) have been analyzed as optical collectors for ultra-weak photon emission (UPE) during the very early germination process. The optical path of the internally-generated light was investigated using a custom ray-tracing numerical code. Specific light maps reveal an optical focus in correspondence with the plumula and radical tip regions of the embryo. Endoscopic photon counting of the emission confirmed the numerical prediction.
