This INSPIRE award is partially funded by the Electronic and Photonic Materials Program and the Biomaterials Program in the Division of Materials Research in the Directorate for Mathematical and Physical Sciences; the Neural Systems Program in the Division of Integrative Organismal Systems in the Directorate for Biological Sciences; the Instrument Development for Biological Research Program in the Division of Biological Infrastructure in the Directorate for Biological Sciences; and the Nano-Biosensing Program in the Division of Chemical, Bioengineering, Environmental, and Transport Systems in the Directorate for Engineering.Technical Description: This research project aims to develop a novel technique to detect electric activities of a neuronal network using voltage-gated optical transitions in graphene. A neuron receives, analyzes and conveys information in the form of electrical signals such as action potentials. The decoding of neural data requires accurate recording of those electrical signals. This project exploits unique electrical and optical properties of graphene to detect electric activities of a neuronal network in a highly parallel and non-invasive manner. It advances scientific understanding in several important fronts, including (1) fundamental understanding of graphene as a unique electronic and optical material for high-sensitivity bio-imaging, (2) interfacing graphene with neuron cells, (3) non-invasive optical detection of action potential, and (4) highly parallel imaging of neuron activity in a neuronal network. This project builds on the complimentary expertise of Professor Wang and Professor Cui on graphene optical spectroscopy and neural electrophysiology, respectively.Non-technical Description: This project captures the tremendous opportunities provided by graphene for optical imaging of neural network activities, which has a potential to become an important tool in neuroscience. The research requires extensive collaboration and exchange of students between Cui and Wang labs, which provides a unique opportunity for graduate and undergraduate students to be exposed to sciences in different disciplines including biology, engineering, materials science, optics, and physics.

该Inspire奖部分由电子和光子材料计划以及数学和物理科学局材料研究部的生物材料计划资助；生物科学局综合生物系统部门的神经系统计划；生物科学局生物基础设施司的生物研究仪器开发计划；以及工程局中化学，生物工程，环境和运输系统的纳米生物传感计划。技术描述：该研究项目旨在开发一种新型技术，以检测使用石墨烯中使用电压门控光学过渡的神经元网络的电动活动。神经元以电信号（例如动作电位）的形式接收，分析和传达信息。神经数据的解码需要准确记录这些电信号。 该项目利用石墨烯的独特电气和光学特性以高度平行和无创的方式检测神经元网络的电活动。它在几个重要方面进行了科学理解，包括（1）将石墨烯作为用于高敏化生物成像的独特的电子和光学材料的基本理解，（2）将石墨烯与神经元细胞接口，（3）动作潜在的非侵入性光学检测，以及（4）神经元网络中神经元的高度平行成像。该项目基于Wang教授和CUI教授在石墨烯光谱和神经电生理学方面的免费专业知识。没有技术描述：该项目捕获了石墨烯为神经网络活动提供的光学成像提供的巨大机会，这有可能成为神经科学的重要工具。 这项研究需要在CUI和Wang Labs之间进行广泛的合作和交流，这为研究生和本科生提供了一个独特的机会，可以接触到不同学科的科学，包括生物学，工程，材料科学，光学和物理学。
