Collaborative Research: Engineering Design of Oxygen Rich Surfaces for Bioelectrodes

这项资助的研究目标是阐明氧在多孔、金属氧化物支撑的生物功能膜中运输、渗透和释放的基本过程，作为生物电极和生物燃料电池的材料。该研究项目将研究金属掺杂和混合金属氧化物在多孔三维网络中的催化、氧化还原、氧储存和释放特性，该网络将用于制造能够在生理和环境温度条件下工作的“富氧”表面。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上氧传输机制的理解，并建立成分、形态和相应的生物电催化性能之间的相关性。这项研究将提高氧的可用性和表面的渗透性，提高生物电极的整体性能。如果成功，这种跨学科的合作将使新一代材料和表面的开发成为可能，这些材料和表面可以在氧气限制的条件下使用。本研究在生物电化学和生物燃料电池领域引入了一种独特的技术，用于促进氧气的流动性和提供储存/释放能力。该研究项目将在学生训练的各个方面促进批判性思维技能的创新和发展，从而为未来的发现奠定知识基础。研究生和本科生，特别是少数民族和妇女，将参与这项研究。K12学生和教师将通过两所合作院校的既定机制接触到这项研究。

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.
