Facilities

A 4-ch FSCV system is set up with a digital stereotaxic device in a faraday cage for animal study. This setup is used to implant neural probes into the animal model and measure dopamine and norepinephrine activites. 

We operate four flow-cells for testing the electrode performance and characteristics. 

The lab is equipped with Neuropixel 2.0 and the complete recording environment. The neuropixel is used to measure the electrical activities from the brain. 

The fluorescence upright microscope (Zeiss Axio Examiner D.1) is specifically tailored for electrophysiology. It is used for opaque substrates, such as silicon substrate. Reflected microscopy is required to image the cultured cell on the surface. The Axio Examiner D.1 is equipped with reflected bright-field, reflected DIC, and reflected fluores-cence capabilities with high-end objective for water-immersion imaging. Faraday cage offers a low-noise environment for electrophysiology.

PlamSens4 is a potentiostat/galvanostat/impedance analyzer. This is used to characterize electrochemical characteristics of our neural probes and electrodes.

The network analyzer is for measuring network parameters for high frequencies, between 300 kHz to 3 GHz. This is used to measure inductance and mutual inductance of wireless coils.

This is for sample cleaning. Harrick Plasma Inc.
