A catalytic thin film was deposited on a porous substrate by a liquid phase method for the synthesis of CNTs as a superhydrophobicsuperoleophilic membrane which is non-toxicenvironmental friendly. The filter membrane was installed on the oil-water separation device for operation without power it’s an important technology for recycling economyenvironmental protection.

We developedoptimized a FRET-based genetically-encoded biosensor Met-lead with high sensitivity 10nM (0.2μg/dL, 2ppb) to fit the related regulations: the safety value of blood lead level for children 3μg/dLWHO-permitted level for tap water 10ppb. We further built a portable smart-phone device to measure Pb on-site. The practical applications of portable Met-lead can fulfill the needs from blood/urine Pb detection to drinking water/environmental irrigation water Pb monitoring, it will also help to build up a warning system to prevent further contamination from heavy metal Pb.
