From UCLA:
Scientists from UCLA’s California NanoSystems Institute have developed a Google Glass app that, when paired with a handheld device, enables the wearer to quickly analyze the health of a plant without damaging it.
The app analyzes the concentration of chlorophyll — the substance in plants responsible for converting sunlight into energy. Reduced chlorophyll production in plants can indicate degradation of water, soil or air quality.
One current method for measuring chlorophyll concentration requires removing some of the plant’s leaves, dissolving them in a chemical solvent and then performing the chemical analysis. With the new system, leaves are examined and then left functional and intact.
The research, led by Aydogan Ozcan, associate director of the UCLA California NanoSystems Institute and Chancellor’s Professor of Electrical Engineering and Bioengineering at the UCLA Henry Samueli School of Engineering and Applied Science, was published online by the Royal Society of Chemistry journal Lab on a Chip.
