Microscopy Reimagined: New PANORAMA System Captures Gigapixel Images of Curved Samples in a Single Shot

A groundbreaking advancement in optical imaging has emerged from Duke University, where researchers have developed a new microscope capable of capturing submicron-resolution gigapixel images of curved samples in a single shot. Named PANORAMA (short for "Curvature-Adaptive Gigapixel Microscopy"), this innovative system merges sophisticated optics with a 48-camera array, offering unmatched detail and speed for materials science, pathology, semiconductor inspection, and more.

Traditional microscopes often struggle with the trade-off between field of view and resolution. Moreover, they assume that samples are perfectly flat—an assumption rarely true in real-world applications involving tissues, plants, or flexible materials. PANORAMA overcomes these barriers by intelligently adapting to surface curvature, delivering sharp imaging across entire samples without scanning or stacking, and doing so in a matter of seconds.

How PANORAMA Works: A Multi-Camera, Multi-Focus Marvel

Instead of scanning across a sample tile-by-tile (a time-consuming and resolution-limited process), the PANORAMA system uses a combination of a telecentric photolithography lens—borrowed from semiconductor manufacturing—and a large tube lens to project the sample onto a grid of 48 independently focused cameras. Each camera adjusts to local variations in sample height, allowing the entire surface to remain in sharp focus regardless of curvature.

The resulting high-resolution images are then seamlessly stitched together using advanced software algorithms. This computational approach allows researchers to achieve gigapixel-scale imaging with less than 10 minutes of post-processing, bypassing the hour-long procedures common to older systems.

Microscopy Without Limits: Applications in Science and Industry

In their experiments, the team imaged biological tissue (rat brain slices) and onion skin laid over a curved surface using both brightfield and fluorescence modes. The PANORAMA system delivered unprecedented detail, revealing structures as small as 0.84 microns—well below the diameter of a human hair—without any blur at the edges. Fluorescence imaging clearly captured cell nuclei, while brightfield images preserved cellular contours and layers.

This innovation opens new doors across numerous fields. In medical diagnostics, entire pathology slides from biopsies can now be scanned instantly. In materials science and chip fabrication, large areas like wafers or flexible electronics can be inspected without missing microscopic flaws. Even plant biology and environmental science stand to benefit from this wide-area, high-resolution capability.

Future Outlook: Automation, Real-Time Video, and 3D

Lead researcher Roarke Horstmeyer and Ph.D. student Haitao Chen note that future upgrades will include larger sensor arrays, automation of individual camera focus, and real-time imaging capabilities. There's also interest in enabling live 3D reconstruction and depth mapping, potentially transforming this technology into a platform for real-time microscopy video of living processes at micro- and nano-scales.

The work was recently published in the journal Optics Letters, under the title: "Curvature-adaptive gigapixel microscopy at submicron resolution and centimeter scale." It signals a major leap forward in the ability to rapidly and accurately image real-world samples across many disciplines.

From Limitation to Liberation: A Paradigm Shift in Imaging

By removing the mechanical limitations of scanning and focusing systems, PANORAMA presents a paradigm shift in how we view microscopic worlds. This technology doesn't just improve imaging resolution or speed—it redefines the limits of what microscopes can achieve. In a field long defined by trade-offs, Duke University's innovation offers a rare win-win: ultra-high resolution and wide field of view—simultaneously.

Quantum Chemistry Meets AI: A New Era for Molecular Machine Learning

Image
In a powerful leap forward for computational chemistry and materials design, researchers from Carnegie Mellon University have developed a new kind of molecular machine learning model—one that goes beyond simplistic molecular graphs and integrates fundamental principles of quantum chemistry. Their work, published in Nature Machine Intelligence , could radically enhance our ability to predict chemical behavior, optimize catalysts, and discover new drugs, all while using less data and gaining more scientific insight. The Problem: Traditional Molecular Representations Fall Short Molecular machine learning (ML) models underpin key processes in drug discovery, materials science, and catalysis. However, most existing models use simplified representations such as SMILES strings, 2D graphs, or coordinate matrices. These techniques often lack the quantum-chemical information that governs how molecules truly behave—particularly electron interactions that define reactivity, stability, and...

Water Simulations Under Scrutiny: Researchers Confirm Methodological Errors

Image
Accurate water simulations are vital for research in biomolecular structures, drug discovery, and materials science. But a recent study from Oak Ridge National Laboratory (ORNL) has revealed a potential pitfall in long-standing computational methods, raising concerns about the reliability of countless molecular dynamics studies. The Time Step Problem in Simulations At the heart of the issue is the “time step” used in simulations—the small intervals at which calculations are performed. Since the 1970s, scientists have used time steps of 2 femtoseconds (quadrillionths of a second) to simulate molecular motion efficiently. However, the ORNL team has shown that using this standard can introduce significant errors when modeling liquid water, potentially leading to inaccurate predictions of properties such as density, pressure, and hydration energies. “Using longer time steps is tempting because it reduces computational cost,” explained senior scientist Dilip Asthagiri. “But a...

CrystalGPT: Redefining Crystal Design with AI-Driven Predictions

Image
July 18, 2025 In a major leap for materials chemistry, researchers in the UK have developed Molecular Crystal Representation from Transformers (MCRT) —an AI model likened to ChatGPT for its transformative impact. Dubbed "CrystalGPT" , this foundation model rapidly predicts the physical properties of molecular crystals, revolutionizing how chemists design materials in silico . The AI Revolution in Crystal Design Understanding and predicting the properties of molecular crystals is critical for designing new materials for applications ranging from pharmaceuticals to energy storage. Traditional computational approaches, though powerful, are often resource-intensive and slow. Machine learning methods such as Smooth Overlap of Atomic Positions (SOAP) and atom-centred symmetry functions (ACSFs) have offered improvements, but they struggle with large datasets and subtle structural nuances. CrystalGPT, developed by a team led by Andy Cooper at the University of Liverpool, o...
