The research objective of this grant is to elucidate the fundamental processes of the oxygen transport, permeability, and release in porous, metal oxide supported biofunctionalized membranes, as materials for bioelectrodes and biofuel cells. The research project will study the catalytic, redox, and oxygen storage and release properties of metal doped and mixed metal oxides within a porous tridimensional network that will be used to fabricate "oxygen-rich" surfaces that are able to operate under physiological and ambient temperature conditions. A suite of spectroscopic, electrochemical, and scanning electrochemical microscopy methods will be used to facilitate understanding of the oxygen transport mechanism at the enzyme/doped metal oxide interface in the porous layer and to establish correlations between composition, morphology, and corresponding bioelectrocatalytic performance. This research will improve oxygen availability and permeability at surfaces, enhancing the overall performance of bioelectrodes.If successful, this interdisciplinary collaborative effort will enable development of a new generation of materials and surfaces that can be used in oxygen restrictive conditions. This research introduces a unique technology in the field of bioelectrochemistry and biofuel cells for facilitating oxygen mobility and providing storage/release capabilities. This research project will promote innovation and development of critical thinking skills in all aspects of student training to develop a foundation of knowledge that will enable future discoveries. Graduate and undergraduate students, especially minorities and women, will participate in this research. K12 students and teachers will be exposed to this research through established mechanisms at the two collaborating institutions.

该资助的研究目的是阐明多孔金属氧化物支持的生物功能化膜（作为生物电极和生物燃料电池的材料）中氧传输、渗透性和释放的基本过程。 该研究项目将研究多孔三维网络中金属掺杂和混合金属氧化物的催化、氧化还原以及储氧和释放特性，该网络将用于制造能够在生理和环境温度下工作的“富氧”表面状况。 将使用一套光谱、电化学和扫描电化学显微镜方法来促进对多孔层中酶/掺杂金属氧化物界面处的氧传输机制的理解，并建立组成、形态和相应生物电催化性能之间的相关性。 这项研究将提高表面的氧气利用率和渗透性，从而提高生物电极的整体性能。如果成功，这项跨学科的合作努力将能够开发出可在氧气限制条件下使用的新一代材料和表面。 这项研究引入了生物电化学和生物燃料电池领域的独特技术，用于促进氧的流动性并提供储存/释放能力。 该研究项目将促进学生培训各个方面的批判性思维技能的创新和发展，为未来的发现奠定知识基础。 研究生和本科生，特别是少数族裔和女性，将参与这项研究。 K12 学生和教师将通过两个合作机构的既定机制接触到这项研究。
