DNA constructs antenna for solar energy

Researchers at Chalmers University of Technology have found an effective solution for collecting sunlight for artificial photosynthesis. By combining self-assembling DNA molecules with simple dye molecules, the researchers ...

Designing a dye you can count on

Natural substances such as chlorophyll and the heme pigment of red blood cells contain colorful molecules known as porphyrins. They owe their exceptional visual characteristics to a ‘macrocyclic’ chemical structure ...

Scientists discover first new chlorophyll in 60 years

(PhysOrg.com) -- University of Sydney scientists have stumbled upon the first new chlorophyll to be discovered in over 60 years and have published their findings in the international journal Science.

Don't Compare Bananas to Pears

(PhysOrg.com) -- Yellow leaves on banana plants give off a blue glow when viewed under UV light. This luminescence comes from decomposition products of chlorophyll, the substance that makes leaves green.

Bananas Gone Bad Glow Blue in UV-Light

(PhysOrg.com) -- Nicholas Turro of Columbia University, Bernhard Krautler of the University of Innsbruck, Austria and their colleagues have found that, as chlorophyll ages and begins to disintegrate in banana peels it does ...

First step to converting solar energy using 'artificial leaf'

An international team of researchers has modified chlorophyll from an alga so that it resembles the extremely efficient light antennae of bacteria. The team was then able to determine the structure of these light antennae. ...
