Hydrothermally carbonized xylem sap for use in chemosensors, on and off switches, and memory devices

Multiple novel chemo sensor devices were created using hydrothermally synthesized fluorescent carbon produced from xylem sap. Most notably, UV light shone on the carbon can be used to selectively detect Fe3+ ions and pH by the “naked eye” instantly, a first for xylem-syrup-derived hydrocarbons. A large stroke shift is present with outstanding photo-stability, sensitivity. NOT, AND, and NOR logic gates were derived using this novel behaviour, …
