Summary

A review published on 2026-07-11 details the transformative role of artificial intelligence (AI) in nanoparticle electron microscopy, shifting it from a descriptive imaging technique to a data-driven platform for structural interpretation, dynamic analysis, and scientific inference. The analysis covers methodologies for transmission electron microscopy (TEM), high-resolution TEM (HRTEM), scanning TEM (STEM), and in situ TEM. It addresses principal challenges like particle detection, segmentation, morphology quantification, atomic-resolution restoration, defect identification, two-dimensional-to-three-dimensional structural inference, and in situ dynamic process analysis. The review examines computational approaches from conventional machine learning and convolutional neural networks to transformer architectures, self-supervised learning, foundation models, multimodal AI, and physics-informed learning. It also discusses integrating microscopy data with simulations, metadata, and autonomous experimentation to relate nanoparticle structure, dynamics, synthesis conditions, and functional properties, critically assessing current methodologies and highlighting opportunities for AI-guided microscopy and autonomous materials discovery.

Key takeaway

For research scientists developing advanced materials or AI scientists working on microscopy data, this review highlights the imperative to integrate diverse AI methodologies, including foundation models and physics-informed learning, into your electron microscopy workflows.
