Application of graphene oxide nanosheet lactate biosensors in continuous assessment of athlete fitness

L-Lactate Electrochemical Biosensor Based on an Integrated Supramolecular Architecture of Multiwalled Carbon Nanotubes Functionalized with Avidin and a Recombinant Biotinylated Lactate Oxidase

“…Dagar et al [42] proposed an amperometric biosensor obtained via covalent immobilization of LOx at a nanohybrid of chitosan, iron oxide nanoparticles, and carboxylated multiwalled carbon nanotubes electrodeposited onto a Au electrode. Deng [43] designed an impedimetric biosensor combining LOx with graphene oxide nanosheets to measure L-lactate levels in sweat with real-time response, which made it possible to monitor the physiological variations in L-lactate from resting states to peak exertion levels. Fernandes et al [44] reported an amperometric biosensor based on carbon fiber microelectrodes modified with Pt nanoparticles and LOx to directly and continuously measure L-lactate levels during Status epilepticus in the rat brain (extracellular space).…”
