Summer Seminar: “High-Density Probes for Multiplexed Chemical Detection in the Brain”

July 8, 2020 Add to Calendar

11 a.m.–12 p.m.




Chemical processes modulate much of the electrical signaling that takes place in the brain. Irregularities in the release and uptake of chemical neuromodulators play a critical role in many neurological disorders. Unfortunately, our ability to perform simultaneous, real-time measurement of the concentration of multiple chemicals in the brain is limited. Jessica Arlett will discuss some of the challenges in the field and how she is overcoming them to develop next-generation, practical, high-density neurochemical sensors.


Jessica Arlett is a visiting assistant professor of physics at Harvey Mudd College. She is an experimental physicist with interest in biochemical sensors, particularly the development of novel approaches to neurochemical detection that can aid in our understanding of neural activity, neurodegenerative diseases, and ultimately the development of advanced neurological treatments. Arlett works in the intersection of physics, chemistry, and biology. Immediate goals are to design, test, and optimize neurochemical sensors for in vivo measurements in mice. We are particularly focused on the question: How can we maximize the sensing of target neurochemicals, while minimizing the noise from other chemicals present in the brain?
