Introduction to Synchrotron Nanocrystallography
Synchrotron nanocrystallography is an advanced structural biology technique that leverages the intense, highly collimated X-ray beams produced by synchrotron light sources to analyze nanometer-scale crystals. This approach has become increasingly vital for elucidating the atomic structures of biological macromolecules and novel materials that are difficult or impossible to grow as large, well-ordered crystals. As of 2025, the field is experiencing rapid growth, driven by technological advancements in synchrotron facilities, detector technologies, and data processing algorithms.
The core principle of synchrotron nanocrystallography involves directing a focused X-ray beam—often with a diameter of less than one micron—onto a nanocrystal. The resulting diffraction patterns are collected and computationally assembled to reconstruct the three-dimensional structure of the sample. This method is particularly valuable for studying proteins, viruses, and complex materials where only nanocrystals are available, overcoming the limitations of traditional crystallography that requires larger crystals.
Globally, several leading synchrotron facilities are at the forefront of nanocrystallography research. Notable examples include the European Synchrotron Radiation Facility (ESRF) in France, the Diamond Light Source in the United Kingdom, and the Advanced Photon Source (APS) in the United States. These organizations have invested heavily in beamline upgrades and the development of micro- and nano-focused X-ray optics, enabling researchers to probe ever-smaller crystals with unprecedented resolution.
Recent years have seen the integration of high-frame-rate detectors and automation, which have dramatically increased data throughput and reduced sample consumption. For instance, the ESRF’s Extremely Brilliant Source (EBS) upgrade, completed in 2020, has set new standards for X-ray brightness and coherence, directly benefiting nanocrystallography applications. Similarly, the APS is undergoing a major upgrade, scheduled for completion in 2024, which is expected to further enhance capabilities for nanocrystal studies.
Looking ahead to the next few years, synchrotron nanocrystallography is poised to play a pivotal role in drug discovery, materials science, and the study of complex biological assemblies. The continued evolution of synchrotron sources, combined with advances in sample delivery and data analysis, is expected to make atomic-resolution structure determination from nanocrystals routine. As more facilities adopt these cutting-edge technologies, the accessibility and impact of synchrotron nanocrystallography will continue to expand, solidifying its status as a cornerstone technique in structural science.
Principles and Mechanisms of Synchrotron Radiation
Synchrotron nanocrystallography leverages the unique properties of synchrotron radiation to probe the atomic structure of nanocrystals with exceptional precision. The fundamental principle underlying this technique is the generation of highly collimated, intense, and tunable X-ray beams by accelerating electrons to relativistic speeds in a synchrotron storage ring. As these electrons are deflected by magnetic fields, they emit synchrotron radiation tangentially to their path, producing a continuous spectrum of X-rays that can be finely tuned for crystallographic experiments.
The mechanism of synchrotron radiation is rooted in the relativistic motion of charged particles. When electrons, traveling at velocities close to the speed of light, are forced to change direction by bending magnets or insertion devices (such as undulators and wigglers), they emit electromagnetic radiation across a broad energy range. The resulting X-ray beams are characterized by their high brilliance, coherence, and small beam size, making them ideal for investigating nanometer-scale crystals that are otherwise challenging to study using conventional X-ray sources.
In 2025, the latest generation of synchrotron facilities—often referred to as diffraction-limited storage rings (DLSRs)—are pushing the boundaries of nanocrystallography. These advanced sources, such as those operated by European Synchrotron Radiation Facility (ESRF), Advanced Photon Source (APS) at Argonne National Laboratory, and SPring-8 in Japan, provide X-ray beams with unprecedented brightness and spatial coherence. This allows for the collection of high-quality diffraction data from crystals as small as a few hundred nanometers, enabling structural determination of proteins, materials, and complex assemblies that were previously inaccessible.
The process of synchrotron nanocrystallography typically involves mounting nanocrystals in the path of the focused X-ray beam. As the beam interacts with the crystal lattice, it produces diffraction patterns that are recorded by fast, sensitive detectors. The resulting data are then processed using sophisticated algorithms to reconstruct the three-dimensional atomic structure. Recent advances in beamline optics, sample delivery systems, and detector technology have significantly improved data quality and throughput, facilitating high-throughput studies and time-resolved experiments.
Looking ahead, ongoing upgrades at major synchrotron facilities are expected to further enhance the capabilities of nanocrystallography. Developments in beam coherence, automation, and data analysis are anticipated to enable routine structure determination from ever-smaller crystals and more complex systems. These advances will continue to drive discoveries in structural biology, materials science, and nanotechnology, solidifying synchrotron nanocrystallography as a cornerstone technique for atomic-scale research in the coming years.
Instrumentation and Beamline Technologies
Synchrotron nanocrystallography has experienced significant advancements in instrumentation and beamline technologies, particularly as global facilities prepare for the next generation of high-brilliance sources and ultra-fast detectors. As of 2025, the field is characterized by the deployment of fourth-generation synchrotron light sources, which offer unprecedented brightness and coherence, enabling the study of ever-smaller crystals and more complex biological and material systems.
Key facilities such as the European Synchrotron Radiation Facility (ESRF), Diamond Light Source, and Advanced Photon Source (APS) have either completed or are in the final stages of major upgrades. The ESRF’s Extremely Brilliant Source (EBS), for example, has set new standards in X-ray beam brilliance and stability, with beam sizes routinely reaching the sub-micrometer scale. These upgrades directly benefit nanocrystallography by allowing for higher signal-to-noise ratios and reduced radiation damage, which are critical for the analysis of nanocrystals.
On the detector front, hybrid pixel array detectors such as the EIGER and JUNGFRAU series are now standard at leading beamlines. These detectors, developed in collaboration with institutions like Paul Scherrer Institute, offer high frame rates (up to several kHz), low noise, and single-photon sensitivity, which are essential for serial crystallography and time-resolved experiments. The integration of fast, automated sample delivery systems—such as fixed-target supports, microfluidic chips, and high-precision goniometers—has further streamlined data collection from nanocrystals, reducing sample consumption and increasing throughput.
Beamline automation and remote access capabilities have also expanded, accelerated by the operational challenges of the COVID-19 pandemic. Facilities now routinely offer remote experiment control, real-time data processing pipelines, and AI-assisted data analysis, making nanocrystallography more accessible to a broader scientific community. For instance, the Diamond Light Source has implemented advanced robotics and machine learning algorithms to optimize crystal centering and data acquisition.
Looking ahead, the next few years will likely see further miniaturization of beam sizes, improved sample environment controls (such as cryo-cooling and humidity regulation), and the integration of complementary techniques like X-ray fluorescence and spectroscopy. The anticipated commissioning of new sources, such as the MAX IV Laboratory in Sweden, will continue to push the boundaries of what is possible in synchrotron nanocrystallography, enabling the structural analysis of increasingly challenging targets in biology, chemistry, and materials science.
Sample Preparation and Handling at the Nanoscale
Sample preparation and handling at the nanoscale are pivotal for the success of synchrotron nanocrystallography, a field that continues to evolve rapidly as new beamlines and instrumentation come online in 2025.

Recent advances in microfluidic technologies and automated sample delivery systems have enabled more reproducible and efficient preparation of nanocrystal suspensions, minimizing sample waste and optimizing the use of precious biological or inorganic materials.
A key challenge in 2025 remains the prevention of aggregation and degradation of nanocrystals during storage and delivery. Cryogenic techniques, such as plunge-freezing and vitrification, are now routinely employed to preserve sample integrity and reduce radiation damage during synchrotron exposure. The use of cryo-electron microscopy (cryo-EM) grids as sample supports has also been adapted for synchrotron nanocrystallography, allowing for direct transfer between modalities and facilitating correlative studies. Additionally, the development of specialized sample holders and micro-patterned chips has enabled high-throughput screening and serial data collection, which are essential for maximizing the efficiency of beamtime at high-demand facilities.
Leading synchrotron facilities, such as the European Synchrotron Radiation Facility (ESRF), Diamond Light Source, and Advanced Photon Source (APS), have invested in dedicated sample preparation laboratories and user support services. These organizations provide standardized protocols, training, and access to state-of-the-art equipment, including robotic liquid handlers, sonicators, and dynamic light scattering instruments for quality control. The integration of artificial intelligence and machine learning for automated crystal detection and classification is also being piloted, promising to further streamline the workflow in the coming years.
Looking ahead, the outlook for sample preparation and handling in synchrotron nanocrystallography is marked by increasing automation, miniaturization, and integration with complementary techniques.

Data collection strategies have evolved to address the challenges posed by nanocrystals, including radiation damage and limited diffracting volume. Serial synchrotron crystallography (SSX) has become a standard approach, wherein thousands of nanocrystals are exposed to the X-ray beam in rapid succession, and single or partial diffraction patterns are recorded from each. This method, supported by high-speed sample delivery systems (e.g., fixed-target chips, microfluidic injectors), allows for the assembly of complete datasets from many crystals, mitigating the effects of radiation damage and crystal heterogeneity.
On the data processing front, software pipelines such as DIALS, CrystFEL, and XDS have been optimized for handling the large volumes of data generated by SSX experiments. These tools incorporate advanced algorithms for spot finding, indexing, and integration, as well as robust merging procedures to combine data from thousands of crystals. Machine learning techniques are increasingly being integrated to improve hit finding and outlier rejection, further enhancing data quality and throughput.
Looking ahead, the next few years are expected to see further automation in both data collection and processing, with real-time feedback systems enabling adaptive experiment control. The integration of artificial intelligence for on-the-fly data assessment and decision-making is anticipated to streamline workflows, reduce human intervention, and maximize the scientific output from precious nanocrystal samples. As synchrotron facilities continue to upgrade their capabilities, the field of nanocrystallography is poised for rapid expansion, enabling routine structure determination of systems previously considered intractable.
