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

近5年来，尚卡尔实验室在氮化碳（CN）基二维荧光材料方面取得了显著的创新成果，如深价带碳纳米管、窄带隙掺杂碳纳米管、羧化富胺碳纳米管、富碳碳纳米管等。尚卡尔实验室主要研究这些CNs在光催化和光伏发电中的应用。该项目将在传感装置中部署氮化碳，利用cnns的电催化行为及其对各种气相和液相分析物的光致发光灵敏度。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在阿尔伯塔大学电气与计算机工程系（ECE）的Shankar实验室和印度BIT-Pilani（海德拉巴校区）电气与电子工程系的Goel实验室之间发起并建立长期的研究合作。Sanket Goel教授是UofA校友，在UofA的ECE系获得博士学位。由Goel教授和Shankar教授共同指导的bit - pilani博士生将前往UofA，研究基于氮化碳的微流体和光致发光器件对二氧化碳、葡萄糖、乳酸和多巴胺等分析物的电催化和光致发光响应。期望从这项工作中获得一个或多个共同撰写的出版物。如果这个初步项目取得成功，将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.
