In biology, AFM has provided unprecedented insights into nanoscale biomolecular organisation under near-physiological conditions, revealing structures and interactions inaccessible to many conventional approaches. However, biological function is inherently dynamic, and understanding molecular mechanisms requires moving beyond static structural snapshots towards direct observation of processes across multiple spatial and temporal scales. In this review, we discuss emerging approaches that are extending the capabilities of AFM beyond traditional imaging, pushing the limits of temporal resolution, spatial precision, quantitative measurement, and data analysis. We highlight advances in speed that enable direct visualisation of molecular dynamics, approaches for sub-millisecond measurements, methods that overcome conventional resolution limits, and computational approaches that enhance image analysis, automation, and information extraction from complex datasets. Together, these developments are transforming AFM from a technique focused primarily on high-resolution structural imaging into a platform for dynamic, quantitative, and high-throughput investigation of biological systems. Finally, we consider how these advances may shape the next 40 years of AFM, enable autonomous measurements and reveal biological mechanisms across previously inaccessible spatial and temporal scales.</p>","PeriodicalId":16484,"journal":{"name":"Journal of microscopy","volume":" ","pages":""},"PeriodicalIF":1.9,"publicationDate":"2026-10-15","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"149194393","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"工程技术","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

In their study 'Deconstructing gastrulation at single-cell resolution,' the authors present an integrated computational framework for cell segmentation, tracking and modelling of cell-cell interactions during Drosophila gastrulation. Their approach combines both generic tools such as ilastik, FIJI, Cellpose, MATLAB code and tools such as ImSAnE to reconstruct whole-embryo, single-cell morphogenetic atlas with unprecedented detail. While the methodology is transparent and well-documented, its implementation relies on multiple software environments and some non-open-source components, limiting full reproducibility and generalisability. Nevertheless, their 'computational framework' exemplifies rigorous data sharing, clear documentation, and methodological transparency aligned with several community guidelines for reproducible image analysis.

Conventional ESR has usually relied on the detection of large spin ensembles, thereby averaging over local environments and suppressing microscopic information that is central to surface science, molecular magnetism, and quantum nanoscience. Scanning probe microscopy (SPM) changes this situation. By combining magnetic resonance with the spatial resolution and manipulation capabilities of scanning tunnelling microscopy (STM) and atomic force microscopy (AFM), ESR can now be performed on individual atoms and molecules on surfaces. This short perspective discusses three connected developments. First, ESR-STM has enabled all-electrical detection and coherent control of individual spins with atomic precision. Second, ESR-AFM has recently provided a complementary route to single-molecule spin resonance based on force-detected pump-probe protocols. Third, these advances are turning surface spins into atomically engineered quantum systems in which spin Hamiltonians, interactions, sensing architectures, and elementary quantum operations can be designed locally. The resulting field does not merely miniaturise conventional ESR; it transforms magnetic resonance into a local quantum tool for spectroscopy, sensing, and coherent manipulation at the atomic scale.</p>","PeriodicalId":16484,"journal":{"name":"Journal of microscopy","volume":" ","pages":""},"PeriodicalIF":1.9,"publicationDate":"2026-10-10","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"149167456","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"工程技术","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The system features high-precision three-axis translation stages with nanometre resolution, enabling accurate spatial scanning. A high numerical aperture (NA) objective lens ensures diffraction-limited optical resolution, while integrated photon-counting modules allow for sensitive detection of photoluminescence signals. The platform supports various spectroscopic measurements, including frequency-resolved and time-resolved photoluminescence. The system incorporates a Hanbury Brown and Twiss (HBT) interferometer for second-order temporal autocorrelation measurements to verify single photon emission. Designed for versatility, the system can accommodate a broad range of QE materials, including organic dye molecules, perovskites, and inorganic semiconductors. Furthermore, the setup enables the study of emission engineering through the manipulation of the local density of optical states, supported by the ability to collect large-scale statistical datasets.
