演讲题目:Electronic Biosensors Harnessing Carbon Nanomaterials
内容摘要
Developing a real-life “medical tricorder” that is sensitive, versatile, and user-friendly for biomarker detection has long been considered the holy grail of biomedical sensing. In our lab, we are working to bring this vision closer to reality by leveraging sp²-bonded carbon nanomaterials produced through scalable chemical vapor deposition (CVD). Our goal is to
develop label-free, sensitive biosensing strategies for early disease diagnosis and continuous health monitoring. In this talk, I will first highlight our progress in the large-scale CVD synthesis of low-dimensional carbons, spanning 1D to 3D structures, both crystalline and quasicrystalline. I will discuss how their unique electrical properties can be harnessed for biomarker detection. Next, I will showcase three label-free sensor platforms developed in our lab: 1) graphene field-effect transistor arrays for detecting nucleic acids and metal ions, 2) graphene Hall sensors for real-time magnetic biomarker sensing, and 3) gradient porous graphene electrodes for wearable sweat analysis and on-body health monitoring. Finally, I will discuss our ongoing work on wearable electronics using carbon nanotube yarns drawn via van der Waals interactions. These developments underscore our efforts to develop a universal label-free biosensing platform, paving the way for the realization of a true “medical tricorder”
