Abstract Scope |
Beyond their application in detection of biomarkers in in vitro settings, electrochemical biosensors have enabled real time study of biological cells, for example in organ-on-chips, as well as in vivo testing. Engineering new functional materials and scalable fabrication of electrochemical biosensors is a growing field. In particular, there has been significant progress in engineering two-dimensional (2D) materials for electrochemical sensing. Sensor electrodes based on 2D materials, specifically graphene, can be also manufactured in a scalable fashion, for example using various printing methods. In this talk, I will highlight our recent progress in printed electrochemical devices based on 2D materials, such as graphene ink, laser induced graphene (LIG), MoS2, and their hybrids for detection of neurotransmitters and metabolites in sweat and saliva as well as real-time study of cancer cells and bacterial biofilms. Advanced biosensing using a recently developed data-fused multimodal approach will be also presented. |
