Robust Biodegradable Optically

Tunable Sheets

“We are developing strong

biodegradable sheets, with

gas barrier properties for the

packaging and agriculture

industry. These sheets are

transparent and can be tuned

to filter unwanted light

wavelengths”

Remote Detection of Buried

Landmines

“Our bacteria glow

when they sense the

chemical signature

of landmines buried

in the soil allowing

safe mapping of the

minefield.”
