As these innovations mature, cryo-ET is anticipated to become a standard tool for elucidating complex molecular interactions in situ, supporting more efficient and informed drug development strategies through 2025 and beyond.
AI and Automation: Accelerating Analysis
Artificial intelligence (AI) and automation are rapidly transforming the field of cryo-electron tomography (cryo-ET), addressing longstanding bottlenecks in data acquisition, image processing, and structural interpretation. As cryo-ET generates immense volumes of complex 3D data, the sector is witnessing a surge in the adoption of AI-powered tools and automated workflows, with significant advancements expected in 2025 and the following years.
In automated data collection, major instrument manufacturers have integrated AI-driven features into the latest generation of cryo-electron microscopes. For example, Thermo Fisher Scientific’s platforms now offer automated targeting and focus optimization, which reduce the expertise and time required for high-throughput tomography. Similarly, JEOL Ltd. has released systems with automated tilt-series acquisition and drift correction, streamlining the data capture process.
AI-based image processing is accelerating the extraction of high-resolution structural information from noisy tomographic datasets. Companies like Carl Zeiss Microscopy are investing in machine learning algorithms for denoising, segmentation, and particle picking, which are crucial for interpreting cellular architecture at the molecular level. These software advances, often embedded within instrument control suites, are expected to shorten analysis times from days to hours, marking a significant leap in workflow efficiency.
Deep learning is also enabling automated annotation and classification of subcellular structures within tomograms. The European Molecular Biology Laboratory (EMBL) and leading cryo-EM facilities are developing open-source AI tools that can identify organelles, macromolecular complexes, and pathological features without manual intervention. Such tools are anticipated to become standard components of cryo-ET pipelines by 2026, further democratizing access to high-level structural insights.

Challenges: Resolution, Throughput, and Accessibility
Cryo-electron tomography (cryo-ET) stands at the frontier of structural biology, offering unparalleled three-dimensional visualization of cellular architectures at near-native states. However, despite significant advances, the field continues to grapple with key challenges in resolution, throughput, and accessibility as of 2025 and looking ahead.
- Resolution Limitations: Achieving atomic or near-atomic resolution in cryo-ET remains a major technical hurdle. While single-particle cryo-EM has reached resolutions below 2 Å, cryo-ET typically operates at more modest resolutions due to sample thickness, electron dose limitations, and the complexities of tilt-series acquisition. Recent developments in direct electron detectors and phase plates from companies such as Thermo Fisher Scientific and JEOL have incrementally improved contrast and resolution, but challenges persist, especially for thick or heterogeneous cellular samples. Novel computational algorithms and AI-driven reconstruction methods are under active development to further enhance resolution in the coming years, yet practical atomic-level detail for in situ macromolecular complexes remains elusive.
- Throughput Bottlenecks: Cryo-ET is inherently low-throughput, largely due to the manual and time-intensive processes of sample preparation (notably cryo-focused ion beam milling), data collection, and tomogram reconstruction. Recent automation efforts, such as the implementation of advanced autoloader cryo-stages and workflow integration by Thermo Fisher Scientific and Leica Microsystems, have begun to address these limitations. Nonetheless, the throughput of cryo-ET remains far below that of single-particle cryo-EM. In the next few years, further software and hardware integration, robotic handling, and machine learning-based analysis are expected to incrementally accelerate cryo-ET workflows, but substantial increases in routine throughput are still a work in progress.
- Accessibility and Cost: The high capital and operational costs of state-of-the-art cryo-TEM instruments, cryo-FIB systems, and supporting infrastructure continue to restrict access primarily to well-funded institutions and national centers. Companies like Thermo Fisher Scientific and JEOL have introduced more accessible platform variants and service models, and initiatives such as shared cryo-EM facilities are growing. However, the overall accessibility gap remains significant, and the anticipated market expansion in the next few years is likely to be gradual unless disruptive cost-reduction strategies emerge.
In summary, while cryo-ET is poised for technological refinement and incremental improvement in 2025 and beyond, overcoming the persistent challenges of resolution, throughput, and accessibility will require coordinated advances in instrumentation, software, and collaborative infrastructure development.
