Benchtop SEM and Sputtercoater
If asked what we’ll be imaging the most with this instrument, the answer will be nanopipets. Our group has demonstrated a vast range of applications for nanopipets e.g., SICM and SECCM imaging, sensing, electrodeposition, local nanoliter sampling, electrospray ionization, etc. For these applications, it is important to clearly characterize nanopipet geometry including the opening radius […]

Potentiometric-Scanning Ion Conductance Microscopy
Potentiometric-Scanning Ion Conductance Microscopy (P-SICM) is a rising sub-class of scanning ion conductance microscopy (SICM) that allows for the simultaneous collection of topography and local apparent conductance. In the Bakergrp, this technique began with past group members such as, Chiao-Chen who started by making single-point measurements (Chen, C. C.; Zhou, Y.; Morris, C. A.; Hou, […]

Our New COMSOL Simulation Horsepower
For electrochemists doing research with scanning probe techniques, COMSOL modeling plays a significant role in instructing experiment design, estimating imaging results affected by pipette geometric, and validating electrochemical phenomena observed. Recently, Baker group has purchased a new server for more efficient COMSOL simulation. The Dell PowerEdge server is specified with 24-core AMD EYPC processor, and […]

NSF CCI Center for Single-Entity Nanochemistry and Nanocrystal Design
A consortium from Indiana University, Texas A&M, Temple and the University of Texas have recently been awarded a grant to establish the NSF Center for Chemical Imaging – the Center for Single-Entity Nanochemistry and Nanocrystal Design. The goal of this center is to address one of the biggest challenges in nanocrystal chemistry – the inherent […]

Fourth SICM System – Delta
Scanning ion conductance microscopy is a versatile tool nanoscale research, including biochemistry, materials, etc. After our first three SICMs: Alpha, Beta and Gamma, we christen our fourth home-made SICM system “Delta” this year. Delta was designed and built by Lingjie. Although this SICM is aimed for fast-scanning, it is good for other kind of work […]

Single-Entity Nanoparticle SECCM
The Baker group studied single-entity electrochemistry in the collaboration with Ye group (Indiana University Bloomington) to study and characterize electrocatalytic activity of single nanocrystals by utilizing scanning electrochemical cell microscopy (SECCM) and correlative microscopy. The methodology framework for SEE suggested here could inform future studies of complex electrocatalytic processes through correlative single-entity and macroscale measurement […]

Ion Channel Probe-SICM
The bakergrp developed ion channel probes (ICP) for SICM to expand the functional sensing capabilities of SICM. The initial stage of ICP-SICM was developed in 2014 by Yi Zhou in collaboration with Craig Aspinwall’s group at the University of Arizona, where α-hemolysin was incorporated within a black lipid membrane at the tip of the pipette.
