Abstract:
Our research focuses on employing Focused Ion Beam (FIB) and Atom Probe
Tomography (APT) to investigate the atomic and molecular signatures in
biological systems. We will first present how to tune various materials using
charged particle beams to fabricate unprecedented 1D and 3D nanostructures.
The fundamental insights into dynamics provide knowledge for precisely
controlling these nanostructures across a wide spectrum of applications.
Additionally, we explore new routes for APT imaging, including the use of
graphene coating to ‘disguise’ the surface of insulated and biological samples.
Successful APT imaging of biological targets, such as antibiotic-resistant bacteria
(superbugs) and proteins, provides us unique atom-by-atom views. New
opportunities for adding laser micromachining to achieve high-throughput
imaging will also be discussed.
