In a seaweed-eating world, a single-celled photochemical organism is located at the top of the ocean and absorbs the most sunlight.
sub-layers, they live in hidden algae that race to chase photons, and the key to their survival is to quickly capture light energy and turn it into food.
related papers were recently published in Chemistry.
the discovery will help create a bionic design for a new generation of optical capture systems.
using ultra-short laser pulses, researchers at Princeton University in the United States found that the surge in algae light capture was due to how energy shifted from one light absorption molecule to another.
in 1 nano second, energy can pass through thousands of molecules, and the exchange of energy between molecules can cause molecular vibrations.
this increase in vibration triggers a chain reaction that allows the sprouted algae to absorb extra light more quickly.
Even on sunny days, sunlight in the ocean is a weak source of photons, not enough to form an enzyme chemical reaction for photosynthmatics, so the recessed algae must be widely webed to capture more photons faster.
" said Gregory Scholes, lead author of the paper, "because they absorb much less light than land plants, it is more important to harvest light quantums."
" current light capture technology is also using similar strategies to improve the light absorption of inorrid molecules, but far from the ability of hidden algae.
it would be useful to develop an organic material that could absorb large amounts of photons in a small area.
"There is no doubt that molecular vibrations are not as effective as those of hidden algae, so we must understand the algae vibrational pathogen, which will help us understand how this organism evolved to optimal light absorption."
