Abstract: Cells inside of our brain are communicating via chemicals. It is important to study the in-brain chemistry to advance our fundamental understanding of the brain and accelerate the findings of targeted therapeutics for various neurological or psychiatric disorders. Recently, leveraging the thermal drawing process, we have successfully developed multifunctional fibers, with optical, chemical, electrical, and mechanical functionalities within a thin strand of fiber. Since I joined FRIS in Tohoku University, we further expanded fiber functionality with in vivo electrochemical sensing modalities. In this seminar, I will discuss in detail our recent work in advancing fiber-based sensors to decipher in-brain intrinsic chemical releases with high selectivity, sensitivity, and spatial-temporal resolution.
First, I will introduce our recent development – the aptamer functionalization on carbon composite fibers for in vivo neurochemical sensing. Then I will discuss the development of the miniature pH imaging devices via the combination of multifunctional fibers with field-effect chemical sensors. Finally, I will also briefly introduce our thermally drawn multi‐electrode fibers for bipolar electrochemistry and show the proof-of-concept of the magnified electrochemical imaging via the tapered fibers.
