The main scientific objective of the project is to appreciate the fundamental principles and theoretical limits of the performance of unique dual feature bioelectrodes, viz. biodevices simultaneously possessing bioelectrocatalytic and charge storage properties. The interdisciplinary project, which combines state-of-the-art nanomaterials, recent discoveries and recent interpretations of various phenomena for constructing truly innovative 3D biodevices with possible future applications in biomedical technology, will entail the fabrication and characterisation of redox active conductive nanobiocomposites, macro- and micro-scale bioelectrodes, as well as manufacturing and investigation of authentic self-charged biodevices. Fabrication and characterisation of entirely new type of bioelectronic devices, viz. membrane-free and mediator-less self-charged biosupercapacitors, by assembling carbohydrate oxidizing and oxygen reducing nanobiocomposite based electrodes, will be done after detailed studies and optimisation of the individual bioelectrodes. Both in vitro and in vivo tests will be performed as a proof-of principle demonstration of highly effective, potentially implantable and disposable electric power sources. The general importance of the work is obvious, since theoretical and practical results obtained in the studies can be used to design efficient and stable self-charging electrodes drawing on conventional, organic/inorganic catalyst based, fuel cell technology.
