At first glance photosynthesis has little or no association with electronics, however there is potentially a strong connection between these two fields of knowledge.
Today, we seek to develop information transmission technologies as fast and compact as possible, reaching the molecular dimension (nanotechnology).
They seek to replace electrons with light in the process of transmitting information, as today is already done in fiber optic cables in telephony. This is where the interface between the two fields of knowledge, photosynthesis and electronics is made.
Fiber optic cable
By understanding how plants absorb light and how they control the movement of this absorbed energy from the antenna to the reaction centers and how to convert light into electrical energy and finally chemical energy, we can build computers on molecular scale. In fact, several logical elements based on artificial reaction centers have been pointed out in the scientific literature.
Photosynthesis and Medicine
Light can be highly harmful if not properly controlled. Examples are the numerous cases of skin cancer. Plants have to absorb light with minimal damage to themselves. Understanding the causes of light damage and natural protection mechanismscan benefit us in areas outside photosynthesis such as medicine. For example, some substances such as chlorophyll tend to localize in tumor tissues. Illumination of these tumors would cause photochemical damage, which could kill the tumor without consequence to healthy tissue.
Another medical application is the use of chlorophyll-like substances to delineate the cancerous area of healthy tissue. Photochemical damage to the tissue is not occurring as the principles of photosynthesis were used to convert the absorbed energy into heat.
