Nanoscale characterisation

Nanoscale characterisation research involves studying materials and structures at the nanometer scale to understand their physical, chemical, and mechanical properties. This research is central to nanotechnology, providing critical insights into material behavior that impact fields like electronics, medicine, and energy. Researchers and students benefit from viewing related PubMed articles paired with JoVE’s experiment videos, which enrich comprehension of complex methods and experimental findings in the materials characterization lab.

Key Methods & Emerging Trends

Established Techniques in Nanoscale Characterisation

Core methods in nanoscale characterisation typically involve electron microscopy, such as transmission electron microscopy (TEM) and scanning electron microscopy (SEM), which provide detailed imaging at the atomic or nanometer scale. Atomic force microscopy (AFM) enables surface topology analysis, while X-ray diffraction (XRD) allows crystal structure determination. These techniques form the backbone of many materials characterization labs, enabling researchers to investigate nanoscale features with high resolution and accuracy.

Emerging Approaches in Nanoscale Imaging

Innovative methods are advancing nanoscale characterisation, including cryo-electron microscopy for studying delicate biological samples at near-atomic resolution and in situ microscopy techniques that track dynamic processes in real time. Additionally, developments in spectroscopic methods combined with nanoscale imaging, such as tip-enhanced Raman spectroscopy (TERS), are enhancing chemical analysis capabilities. These emerging tools expand possibilities for analyzing complex nanostructures and deepen insights into what is so special about the nanoscale.
