CIQTEK Electron Microscopy Advances its Global Footprint at ESEM 2025 in Egypt

CIQTEK is honored to have participated in the Egyptian Society of Electron Microscopy (ESEM) International Conference 2025, held October 13–15 at the Theodor Bilharz Research Institute (TBRI) in Giza, Egypt. This event convened electron microscopy experts, researchers, and industry representatives from across the Middle East, Africa, and beyond, advancing the frontiers of microscopy in both life sciences and materials research.

This year’s theme, “The Role of Electron Microscopy in Enlightening the Invisible”, resonated across sessions on neuropathology, renal biopsy, infectious agents, nanostructure imaging, and emerging microscopy techniques. TBRI played a central role in organizing the event, in cooperation with Egyptian universities such as Tanta and Assiut.

Impact & Outlook

The conference underscored how microscopy continues to unveil the unseen—from cellular ultrastructure to nanomaterial phenomena. For many participants, this was a rare opportunity to access a wide spectrum of imaging techniques under one roof, and to converse directly with vendors like CIQTEK.

 

By engaging with local scientists and institutions, CIQTEK deepens its global reach and contributes to the growth of microscopy in underrepresented regions. We look forward to continuing our support in Africa and the Middle East through instrument installations, training, and responsive service.

CIQTEK Unveils 4D-STEM Solution for Advanced Electron Microscopy

Four-dimensional scanning transmission electron microscopy (4D-STEM) is one of the most cutting-edge directions in electron microscopy. By performing a two-dimensional scan across the sample surface while recording a full diffraction pattern at each scan point with a pixelated detector, 4D-STEM generates a four-dimensional dataset containing both real-space and reciprocal-space information.

This technique breaks through the limitations of conventional electron microscopy that typically collects only a single scattering signal. Instead, it captures and analyzes the entire spectrum of electron–sample interactions. With 4D-STEM, researchers can achieve multiple advanced functionalities within a single experiment, including virtual imaging, crystal orientation and strain mapping, electric and magnetic field distribution analysis (differential phase contrast), and even atomic-resolution reconstruction through diffraction stacking. It greatly expands the dimensionality and depth of materials characterization, offering an unprecedented tool for nanoscience and materials research.

 

At the Chinese National Conference on Electron Microscopy 2025 (Sept 26–30, Wuhan), CIQTEK releases its 4D-STEM solution, designed to break through the boundaries of traditional imaging and deliver data with unmatched dimensionality and analytical power.

CIQTEK Cryo-SEM Solution Enables Damage-Free, High-Resolution Imaging of Biological Samples

In the fields of life sciences, biomedicine, food inspection, and soft matter research, achieving high-resolution imaging of hydrated and beam-sensitive samples has always been a major challenge. Conventional sample preparation methods, such as chemical fixation, dehydration, and drying, often result in shrinkage, deformation, or structural damage, leading to results that deviate from the true state of the sample.

 

Leveraging its advanced scanning electron microscopy technology, CIQTEK has introduced the Cryo-SEM Solution, which integrates low-temperature freezing and vacuum transfer. This enables in-situ, non-destructive, and high-fidelity microscopic observation of biological and sensitive samples, truly “freezing” the microscopic details of life.

 

With liquid-nitrogen slush rapid-freezing technology, samples can be vitrified instantly at -210 °C, preserving their original morphology and chemical composition to the greatest extent. The integrated cryo-preparation system combines freeze-fracture, sublimation coating, and low-temperature transfer, avoiding the complexity and potential errors of conventional manual preparation. Throughout the entire process, samples are maintained under cryogenic vacuum conditions and transferred to the SEM cryo-stage, where high-resolution imaging at -180 °C effectively suppresses electron beam damage and significantly improves image quality.

In addition, the system offers strong compatibility, adaptable across CIQTEK's full range of SEMs and dual-beam FIBSEM systems, meeting diverse needs from routine observation to advanced analysis.

 

The CIQTEK Cryo-SEM Solution is more than just a set of instruments. It embodies a scientific approach dedicated to faithfully restoring the microscopic world. It empowers researchers to overcome technical limitations, capture critical details at the micro scale of life, and drive both fundamental research and applied development to new heights.

 

September 26–30, Wuhan

At the 2025 Chinese Electron Microscopy Academic Conference, CIQTEK will unveil eight cutting-edge EM solutions.
