Nanoelectrode Probe for Scanning Nanoelectrochemistry and Nanoelectrical Liquid Imaging

In situ, multimodal, nanoscale imaging is highly desired for today’s multidisciplinary research, e.g. energy, material and biological studies.

Webinar Overview

In situ, multimodal, nanoscale imaging is highly desired for today’s multidisciplinary research, e.g. energy, material and biological studies. Bruker recently developed batch-fabricated, robust nanoelectrode probes that have an exposed, active Pt tip apex of ~250 nm height and an end tip radius of ~25 nm. These probes are used in PeakForce Scanning Electrochemical Microscopy (PeakForce SECM) for simultaneous capture of topography, conductivity, and quantitative nanomechanical information at the nanoscale, and electrochemical properties at sub-100 nm resolution. Bruker also developed Force Volume SECM providing improved electrochemical kinetic quantification, 3-D nano-electrochemical and nanomechanical mapping. The nanoelectrode probe - by design - also enables nanoelectrical measurements in liquid, in particular PeakForce-TUNA, PeakForce-KPFM and PFM. In this talk, Dr. Huang will introduce these unique techniques with a variety of applications examples related to today’s highly multidisciplinary research.

Dr. Teddy Huang is a Staff Applications Scientist at Bruker. He obtained his PhD degree in physical chemistry from Emory University in 2012. After graduation, he worked for Prof. Nathan Lewis at Caltech as a postdoctoral scholar, where he investigated the semiconductor/metal interfacial structure using AFM nanoelectric measurements. He joined in Bruker in 2014 and now leads the team for development of AFM-based electrical and electrochemical applications. As of today, he has published 43 peer-reviewed articles with more than 2300 citations and an H-index of 22.
