Synthetic biologists have developed a prototype for an innovative biosensor that can detect rare earth elements and be modified for a range of other applications.
QUT synthetic biologists have developed a prototype for an innovative biosensor that can detect rare earth elements and be modified for a range of other applications.
Along with Professor Alexandrov, the international research team involved QUT researchers Dr Zhong Guo, Patricia Walden and Dr Zhenling Cui, in collaboration with researchers from CSIRO Advanced Engineering Biology Future Science Platform and Clarkson University ., the team describe engineering a hybrid protein, or"chimera," by combining a lanthanide-binding protein, LanM, with an antibiotic degrading enzyme called beta-lactamase.
"This work opens up exciting possibilities for using biology to detect and recover rare earth metals," Professor Alexandrov said. "We also want to explore using the tool to engineer microbes that can directly extract rare earth minerals from ocean water," Professor Alexandrov said.
