Miniaturization technology and nanostructured materials have led to significant advances in many fields, including biomedical sciences. In this webinar hosted by the Optoelectronics Technical Group, Erkin Şeker will describe his research efforts to control nano-/micro-scale properties of nanoporous gold (np-Au), which had mostly attracted attention for catalysis applications while its biomedical applications were nascent.

Specifically, Prof. Şeker will discuss the development of np-Au-based multifunctional electrode arrays for monitoring/modulating neural activity and electrochemical nucleic acid sensors that can operate in complex biological matrices. Prof. Şeker will then discuss ongoing efforts toward implementing the described technologies into microfluidic tissue chips plated with primary rat cortical cells and vagal afferent neurons. The webinar will conclude by illustrating the versatility of the neural tissue chips for modeling various physiological phenomena broadly related to the gut-brain axis, neuroinflammation, and neurodegeneration.

Subject Matter Level: Advanced - Assumes a strong understanding of the topic

What You Will Learn:
• How does the integration of nanoporous gold (np-Au) in electrode arrays and nucleic acid sensors enhance their functionality in biomedical applications compared to other materials?
•How neural tissue chips are fabricated and what are some critical applications in neurophysiology?

Who Should Attend:
• Researchers and industry personal working optics, photonics, optoeletronics, and biomedical engineering
• Graduate students
