A new study shows that iron-bearing rocks that formed at the ocean floor 3.2 billion years ago carry unmistakable evidence of oxygen. The only logical source for that oxygen is the earliest known example of photosynthesis by living organisms, say University of Wisconsin–Madison geoscientists.

In artificial photosynthesis, scientists are essentially conducting the same fundamental process that occurs in natural photosynthesis but with simpler nanostructures. The fabrication of these nanostructures has only recently been possible due to breakthroughs in nanotechnology in the areas of imaging and manipulation. With the core processes in photosynthesis being light gathering, charge separation, and recombination, the goal of scientists has been to create efficient synthetic nanostructures that can function as antennae and reaction centers. Devens Gust and fellow researchers at Arizona State University created a hexad, or six-part, nanoparticle made of four zinc tetraarylporphyrin molecules, (PZP)3-PZC, a free-base porphyrin, and a fullerene molecule, P-C60.

Photosynthesis is a process where by energy from light is harvested and used to drive synthesis of organic carbohydrates from carbon dioxide and water. Photosynthesis takes place in chloroplasts and can be divided into two steps: light reactions which require light and dark reactions which do not require light. During light reaction, light energy is captured by photosystems and electrons are transferred among the electron receptors. ATP and NADPH are generated. During dark reactions, CO2 is fixed using ATP and NADPH generated by the light reactions and organic carbohydrates are synthesized via the Calvin Cycle. When the CO2 is first fixed into a 3 carbon compound 3PGA, it is called C3 pathways and these plants are called C3 plants. The disadvantage of C3 plants is that they undergo photorespiration and thus waste some energy gained in light reactions. C4 cycle is the pathway adopted by C4 plants to bypass photorespiration.

Summary of the different photosynthetic pathways. C3 plants fix CO2 directly, using the enzyme ribulose bisphosphate carboxylase oxygenase (Rubisco), reaction CO2 with ribulose bisphosphate (RuBP) to form PGA in the chloroplasts of the mesophyll. C4 plants react PEP carboxylase to react CO2 with phosphoenolpyruvate (PEP) to form oxaloacetic acid, which is in turn converted to malate. This is transferred to the bundle sheath, where malate is broken down to release CO2, which is used by Rubisco. CAM plants use PEP carboxylase to fix CO2 at night and then break down the malate so produced during the day to provide CO2 for Rubisco.
