Development of glucose-oxidising enzyme electrodes for application in glucose|oxygen powered enzymatic fuel cells
Osadebe, Isioma (2016-02)The objective of this thesis is to investigate different strategies for the optimisation of biocatalytic anodes with a view to developing a semi- or fully implantable, miniature, membrane-less enzymatic fuel cell via ... -
Development of Mediated Enzymatic Fuel Cells for Operation in Blood
Mac Aodha, Domhnall (2013-07)The process of enzymatic catalysis of glucose oxidation releases electrons which, when harnessed to flow through a circuit, may be utilised to power devices. This principle has driven research towards the goal of providing ... -
Mediated glucose biosensors for application in continuous glucose monitoring
Jayakumar, Kavita (NUI Galway, 2023-04-19)Diabetes affects 1 in 11 people globally and requires monitoring of blood glucose levels as a part of its treatment. Initial blood glucose monitoring devices involved finger prick testing at regular intervals daily, a ... -
Open-source bioelectronics for development of electrochemical biosensors and assays
Mercer, Conan (NUI Galway, 2019-02-20)This thesis presents steps in the development of open-source bioelectronics that gather together and combine in the demonstration of a system capable of operating a fully integrated wireless electrochemical biosensor. -
Peroxidase-based electrochemical detection using osmium complexes as mediators: application to sensing and immunoassays
Mandal, Tanushree (NUI Galway, 2023-05-16)Horseradish peroxidase (HRP) is an oxidoreductase enzyme that has been used in many bio-electrochemical applications such as biosensors, immunoassays, fuel cells etc. Osmium polypyridyl complexes are advantageous as mediators ... -
Surface modification of electrodes for enzymatic fuel cell application
Kumar, Rakesh (2016-01-07)The immobilisation chemistry of enzymes and redox complexes capable of shuttling electrons between enzymes and electrode surface can have an impact on the magnitude and stability of current response, with implications for ... -
Tailoring surfaces and supports for enzyme electrodes with application to biopower device development
Ó Conghaile, Peter (2014-01-06)The objective of this thesis was to investigate the integration of enzymes and redox mediators capable of transferring electrons between enzymes and electrodes. This was done with a view to developing a semi- or fully ... -
Towards improved performance of mediated glucose oxidising enzyme electrodes for biosensing and biopower applications
Bennett, Richard W. (NUI Galway, 2019-11)Energy produced through enzymatic catalysis at electrodes, namely oxidation of glucose and reduction of oxygen may be used to power devices. The goal of powering implantable or semiimplantable medical devices through ...
