Conductive Photoresist for Nanoscale 3D Printing

I am currently beginning work with Dr. Timothy Otchy to develop a conductive photoresist suitable for the efficient and effective fabrication of custom nano- and micro-scale devices via two-photon polymerization (2PP). The goal of this project is to be able to quickly and efficiently print arbitrarily complex, conductive devices for recording electrical activity in the nervous system that fits the shape and scale of different structures in the system.

This project was inspired by research conducted by Natalia A. Bakhtina et al from the University of Freiburg. They were able to develop a composite photoresist via 2PP with a conductivity of up to 4 S/cm. While this is an improvement on existing technology, electrophysiology recordings require conductivity on the order of 100-500 S/cm, driving the need for new materials.

This page will be updated as the research progresses.
