WebJan 19, 2024 · Introduction The solar energy of the sun has been an external power source to earth for 4.5 billion years. Around 3.4 billion years ago, the earth developed a method to store solar energy in chemical bonds through photosynthesis by cyanobacteria and later by plants. 1 Since the discovery of fire, humans have been using various forms of stored … WebThe work reported here shows that these dyes can also be converted to forms that are excited by green light and emit red fluorescence. This was observed both in whole tissues …
