It's a blend of biology, chemistry, and environmental science that could change the world—and maybe inspire your next science fair project!
Speak like a Scholar

Photosynthesis
The process by which green plants and some other organisms use sunlight to synthesize foods from carbon dioxide and water. In the ocean, algae and seaweeds are the champions of this process.

Nanostructures
Tiny structures, often smaller than the wavelength of light, that can manipulate light in unique ways, much like how certain marine organisms create their vivid colors.

Bio-photoreactors
Devices that use a biological component, such as algae, to capture and convert light into energy, mimicking the natural process of photosynthesis but on a potentially industrial scale.

Bionic systems
Systems that combine biological elements with artificial devices or structures to create new capabilities, like enhancing light absorption in algae.

Structural color
Colors produced by the interaction of light with tiny, structured surfaces rather than by pigments. Butterfly wings and peacock feathers are classic examples, and some marine organisms use this for camouflage or attracting mates.

Biomass
Organic material that comes from plants and animals, and it is a renewable source of energy. In this context, it refers to the growth of microalgae that can be used for biofuel production.
