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.”
