Electrochemical and Spectroelectrochemical Sensing Devices Based On Active Layers Consisting of Carbon Nitride Nanosheets

在过去的5年里，Shankar实验室在氮化碳（CN）基荧光二维材料方面取得了值得注意的创新，例如具有深价带的CN，具有窄带隙的掺杂CN，羧化和富含胺的CN，富含碳的CN等。该项目将利用氯化萘的电催化行为及其光致发光对各种气相和液相分析物的敏感性，在传感装置中使用氮化碳。Sanket Goel教授是用于化学传感和即时生物诊断的低成本微流体传感平台的新兴领导者。该项目的第二个目标是发起并建立阿尔伯塔大学电气与计算机工程系（ECE）的Shankar实验室与印度BIT Pilani（海得拉巴校区）电气与电子工程系的Goel实验室之间的长期研究合作。Sanket Goel教授是UofA校友，于年在UofA的ECE部门获得博士学位。一名博士生就读于BITS-Pilani，由Goel教授和Shankar教授共同监督，他将前往UofA，研究基于氮化碳的微流体和毫米级传感设备对CO2，葡萄糖，乳酸盐和多巴胺等分析物的电催化和光致发光响应。一个或多个共同撰写的出版物预计从这项工作。如果这一初步项目取得成功，计划在传感器领域申请更大的赠款。

In the last 5 years, the Shankar Lab has made noteworthy innovations in carbon nitride (CN) based fluorescent 2D materials such as CNs with a deep valence band, doped CNs with a narrow bandgap, carboxylated and amine-rich CNs, carbon-rich CNs, etc. The Shankar Lab has mostly studied the applications of these CNs in photocatalysis and photovoltaics. This project will deploy carbon nitrides in sensing devices that exploit the electrocatalytic behavior of CNs and the sensitivity of their photoluminescence to various vapor-phase and liquid-phase analytes. Prof. Sanket Goel is an emerging leader in low cost, microfluidic sensing platforms for chemical sensing and point-of-care biodiagnostics. A secondary goal of this project is to initiate and establish a long-term research collaboration between the Shankar Lab in the Department of Electrical & Computer Engineering (ECE) at the University of Alberta and the Goel Lab in the Department of Electrical & Electronics Engineering at BIT-Pilani (Hyderabad Campus), India. Prof. Sanket Goel is a UofA alumnus having obtained his PhD in the ECE department at the UofA in. A PhD student enrolled at BITS-Pilani who is jointly supervised by Prof. Goel and Prof. Shankar will travel to the UofA and study the electrocatalytic and photoluminescence response of carbon nitride-based microfluidic and millimeter-sized sensing devices to analytes such as CO2, glucose, lactate and dopamine. One or more jointly authored publications are expected from this work. If this initial project is successful, larger grant applications in the field of sensors are planned.
