Clinically Informed Intelligent Classification of Ovarian Cancer Cells by Label‐Free Holographic Imaging Flow Cytometry

Advanced Intelligent Systems, Volume 7, Issue 3, March 2025.
Quantitative phase maps of single cells recorded in flow cytometry modality feed a hierarchical architecture of machine learning models for the label‐free identification of subtypes of ovarian cancer. The employment of a priori clinical information improves the classification performance, thus emulating the clinical application of liquid biopsy during ...

Interferometric Scattering Microscopy (iSCAT): A Perspective on Visualizing and Engineering Electrode Homogeneity for Advanced Lithium‐Ion Batteries

Carbon Energy, EarlyView.
Electrode state‐of‐charge heterogeneity critically limits lithium‐ion battery performance and safety. This Perspective highlights iSCAT, a powerful optical technique for real‐time, nanoscale visualization of lithium dynamics within single particles. By revealing the origins of heterogeneity, iSCAT enables rational electrode design.
