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.

在过去的5年里，香卡实验室在基于氮化碳(CN)的荧光2D材料方面取得了令人瞩目的创新，如深价带碳纳米管、窄禁带掺杂碳纳米管、羧化富胺碳纳米管、富碳碳纳米管等。该项目将在传感设备中部署氮化碳，利用CNS的电催化行为及其光致发光对各种气相和液态分析物的敏感性。Sanket Goel教授是用于化学传感和护理点生物诊断的低成本微流控传感平台的新兴领导者。该项目的第二个目标是启动和建立艾伯塔大学电气和计算机工程系的Shankar实验室和印度比特-皮拉尼(海德拉巴校区)电气和电子工程系的Goel实验室之间的长期研究合作。Sanket Goel教授是美银美林的校友，在美银美林的欧洲经济学系获得博士学位。在BITS-Pilani注册的一名博士生将在Goel教授和Shankar教授的共同指导下前往美国大学，研究基于氮化碳的微流控和毫米尺寸传感设备对二氧化碳、葡萄糖、乳酸和多巴胺等分析物质的电催化和光致发光响应。预计这项工作将出版一本或多本共同撰写的出版物。如果这一初步项目成功，将计划在传感器领域提出更大规模的赠款申请。
