SU research team uses nanobiotechnology-manipulated light particles to accelerate algae growth
Date:8/24/2010

catter blue light into the algae culture. Through model-guided experimentation, the team discovered that by varying the concentration and size of the nanoparticle solution they could manipulate the intensity and frequency of the light source, thereby achieving an optimal wavelength for algal growth.

"Implementation of easily tunable wavelength specific backscattering on larger scales still remains a challenge, but its realization will have a substantial impact on the efficient harvesting of phototrophic microorganisms and reducing parasitic growth," says Sureshkumar. "Devices that can convert light not utilized by the algae into the useful blue spectral regime can also be envisioned."

To date, this is one of the first explorations into utilizing nanobiotechnology to promote microalgal growth. The acceleration in the growth rate of algae also had numerous benefits outside the area of biofuel production. Sureshkumar and Wani will be looking to employ this discovery to further their research in creating environmental sensors for ecological warning systems.
