HKUST Develops World’s Smallest Multifunctional Biomedical Robot for Interventional Diagnosis and Treatment

HONG KONG, Jan. 20, 2025 /PRNewswire/ — Researchers from the School of Engineering of the Hong Kong University of Science and Technology (HKUST) have successfully developed the world’s smallest multifunctional biomedical robot, which is 60% smaller than current models. Capable of imaging, high-precision motion, and multifunctional operations like sampling, drug delivery, and laser ablation, the robot offers competitive imaging performance and a tenfold improvement in obstacle detection, paving the way for robotic applications in narrow and challenging channels of the human body, such as the lung’s end bronchi and the oviducts.

With a slim profile of just 0.95 mm—60% smaller than current endoscopic robots—this robot has accomplished an “impossible trinity” by simultaneously integrating all three significant specifications in one robot. It offers competitive imaging performance and extends obstacle detection distance up to ~9.4 mm, a tenfold improvement from theoretical limits. It also achieves remarkable motion precision (less than 30 μm) and substantially widens the imaging region by ~25 times the inherent view.

Developed by Prof. SHEN Yajing, Associate Professor at the Department of Electronic and Computer Engineering (ECE) and his team, the robot’s tiny size is made possible with four major components. These include an optical fiber array for capturing images inside the body, a custom tool for delivering treatments precisely where needed, a hollow skeleton to hold the fibers and tools in place, and a functionalized skin that enables precise control of the robot’s movements. The hollow skeleton is created by a microscale 3D printer, while the functionalized skin is produced through a magnetic spray technique, which helps keep the robot small and allows it to glide easily during surgery. It also features a gel-like outer layer that reduces friction. The team has tested this robot within in vitro bronchial models and ex-vivo porcine lungs, demonstrating smooth navigation in tight spaces while successfully capturing clear images and performing treatments on difficult areas.

Prof. Shen said that this groundbreaking robot holds tremendous potential for clinical applications. “Small-scale continuum robots hold promise for interventional diagnosis and treatment, yet existing models often struggle with compactness, precise navigation, and visualized functional treatment all in one. Our study provides a significant solution for developing a surgical robot aimed at achieving early diagnosis and therapeutic goals in hard-to-reach areas of the body. With ongoing technological advancements, we believe that the fiberscopic robot will make greater contributions to human health in the foreseeable future,” he said.

Thanks to their ability to navigate narrow cavities while enabling quick recovery and low infection risk, small continuum robots have been employed in the treatment of several diseases, including heart disease—through the deployment of stents and electrophysiology catheters—as well as the repair of perforations in gastric and duodenal ulcers using single-port laparoscopy, among other applications. Building on this successful invention, the research team plans to further refine the robot’s features to fit them into practical settings.

“We aim to further optimize the design and control of the fiberscopic robot, prioritizing safety and reliability during interventional surgery. We look forward to implementing in vivo trials to demonstrate its performance in clinical scenarios,” said Dr. ZHANG Tieshan, a postdoctoral fellow at HKUST. He is one of the two co-first authors of the study, along with Dr. LI Gen. Other co-authors from HKUST include Research Assistant Professor Dr. YANG Xiong and PhD student ZHAO Haoxiang, also from the ECE Department. Their findings have been recently published in Nature Communications.

MARRAKECH, Morocco, Oct. 27, 2026 /PRNewswire/ — The International Association of Anti-Corruption Authorities (IAACA), an independent and non-political anti-corruption organisation with over 190 member anti-corruption authorities (ACAs) worldwide, will co-host IAACA Annual Conference 2026 in Marrakech, Morocco next month together with the Independent Commission Against Corruption of Hong Kong, China (ICAC) and the National Authority for Probity, Prevention and Fight Against Corruption of Morocco (INPPLC) to chart a path for the global graft fight and explore cutting-edge approaches to tackle emerging corruption challenges.

Themed “Building on 20 Years of Legacy: Drawing Strength from the Past, Guarding Global Integrity for the Future”, the international event will not only mark the 20th anniversary of the IAACA, but also provide a dynamic forum for IAACA members to exchange insights and enhance co-operation.

Calling on international counterparts to participate in the conference scheduled for November 25, IAACA President Mr Woo Ying-ming, who also serves as ICAC Commissioner, said that “As the IAACA marks its 20th anniversary, the conference will bring together global anti-corruption community at a pivotal moment for collective action. I anticipate that the valuable insights and new approaches generated through the international synergy will chart a resilient strategic path for us to navigate integrity risks and draw strength from our shared legacy to guard global integrity for generations to come.”

During the conference, renowned international experts from the United Nations Office on Drugs and Crime (UNODC), Basel Institute on Governance, the International Anti-Corruption Academy, and global anti-corruption and law enforcement agencies and institutions will shed light on harnessing artificial intelligence in the fight against corruption, safeguarding integrity within global climate and biodiversity frameworks and analysing global corruption measurement and systemic effectiveness.

Following the conference, the ICAC, the INPPLC, the IAACA and the UNODC will co-organise a training seminar on leveraging AI in combating corruption.

While the ICAC and INPPLC will share how AI and new technology can reshape the future of anti-graft enforcement and corruption prevention, the UNODC will provide a global perspective on using AI models in financial crime investigations and addressing the operational relevance, legal robustness and adaptability across jurisdictions.

HANOI, Vietnam, Oct. 27, 2026 /PRNewswire/ — Viettel High Technology Industries Corporation (Viettel High Tech), part of Viettel Group, has migrated more than 100 million subscribers and some 5,000 tariff plans at Viettel, Vietnam’s largest mobile operator, to vOCS 4.0, its in-house cloud-native charging system. The three-month cutover ran on a live national network with no service disruption.

Replacing a charging system is one of the riskiest projects an operator can undertake, which is why many stick with legacy platforms. Viettel High Tech reduced the risk through real-time data synchronization, parallel running and a phased cutover, with instant rollback at every stage.

The project won the Telecom Review Excellence Awards 2026 prize for Best Technology Deployment in Asia, a first for a Vietnamese company.

What it means for operators:

Scale: more than 300,000 transactions per second at latency below 5 milliseconds, across 2G–5G and fixed services on one platformLower cost: up to 50% less hardware investment than the previous generation, by sharing infrastructure with the networkAgility: new tariff plans in hours instead of days, new features three times faster and deployments about 30% fasterResilience: two active data centers about 2,000 km apart and automatic recovery in under two minutes

Viettel High Tech developed every core layer in-house, from a telecom-grade cloud-native platform and NFV-MANO orchestration to real-time charging, subscriber and balance management.

“Passing rigorous tests of real-time self-diagnosis and self-recovery is what allows an operator to keep its promise of 24/7 service to customers,” said Luu Manh Ha, CEO of Viettel Networks, which operates the system on Viettel’s network in Vietnam. “Above all, owning the charging system means an operator is not dependent on foreign vendors – it safeguards digital sovereignty and preserves business flexibility.”

“The charging system is where an operator’s business strategy turns into revenue in real time,” said Nguyen Minh Quang, CEO of Viettel High Tech. “We believe vOCS 4.0 is ready to help operators worldwide capture the value of 5G and digital services.”

In 2017, vOCS 4.0’s predecessor, vOCS 3.0, replaced a foreign vendor’s platform for 90 million Viettel subscribers. Across both generations, vOCS serves more than 220 million subscribers in 11 countries. Viettel High Tech now offers vOCS 4.0 to operators worldwide.
