在副系主任及教授李建華教授、和助理教授王搢珽教授的指導下，團隊首創以「胜肽連接系統」改造巨噬細胞，取代傳統T細胞，為治療實體腫瘤提供嶄新方案。該平台適用於 92% 的惡性腫瘤，並兼具更快捷、安全性佳及可實現個人化治療，極具市場潛力。

👏 恭喜兩位年輕科研人才取得傑出成就！

🌟 PolyU students’ cancer research achieves top honours in innovation and life sciences 🌟

Miss Rainbow Leung Wing Hei (PhD student) and Dr. Martina Lei Mang Leng (graduate) from PolyU’s Department of Applied Biology and Chemical Technology delivered an exceptional performance at the 12th Hong Kong University Student Innovation and Entrepreneurship Competition.

With their groundbreaking project, “Therapeutic efficacy of peptide-linked chimeric antigen receptor macrophages (pCAR-M) in solid tumors,” the team won the Grand Prize in the Innovation category and the First Prize in the Life Sciences category.

Supervised by Prof. Terence Lee Kin‑wah, Associate Head and Professor, and Prof. Clarence Wong Tsun‑ting, Assistant Professor of the same department, the project pioneers a peptide‑linked system to engineer macrophages instead of T cells, offering a novel approach to treating solid tumours. The pCAR‑M platform is faster, safer, and more accessible, with potential applicability to 92% of malignant tumours, unlocking vast opportunities in the solid-tumour market.

👏 Congratulations to our young innovators for their remarkable achievement!

【PolyU all-acoustics brain-computer interface system forges new paths for Parkinson’s disease therapy✨】

An ageing population is often accompanied by an increase in age‑related disorders such as Parkinson’s disease, an incurable neurodegenerative disorder that impairs body movement and which is mainly alleviated by medicines or surgical procedures.
A research team led by Prof. Sun Lei, Director of the Research Centre for Non-invasive Brain Computer Interface and Prof. Qiu Zhihai, a PhD graduate and Professor of the Department of Biomedical Engineering at PolyU, has developed the next‑generation “All‑Acoustics Brain‑Computer Interface (BCI) System”, leveraging “transcranial ultrasound neuromodulation” to deliver fully non‑invasive, deep‑brain and high‑precision neural modulation with ultrasound. The system presents a promising new therapeutic approach for treating Parkinson’s disease, as well as other neurological and psychiatric disorders. 💡

The team has validated the technology’s efficacy through animal studies. In the next stage, Prof. Sun will expand the scale of clinical validation. He plans to collaborate with five leading medical centres in China to conduct a clinical study involving 100 Parkinson’s disease patients and systematically assess the ultrasound technique’s safety and efficacy, paving the way for regulatory approval and commercialisation. 🏥 Looking ahead, the team also aims to partner with Hong Kong hospitals for clinical study and develop a more portable household version of the system, enabling patients to receive continuous treatment at home. 💪

ULS Workshop - Exploring the STELLARIS 8 FALCON Confocal Platform from Leica

The University Research Facility in Life Sciences (ULS) is co-organizing a workshop on advanced confocal and functional imaging with Leica. This workshop will focus on the STELLARIS 8 FALCON, a next-generation platform that integrates high-speed lifetime imaging with a fully tunable white light laser to push the boundaries of conventional confocal microscopy. On-site imaging advice will be provided by Application Specialists from Leica Microsystems.

Key Specifications:

White Light Laser: Fully tunable excitation (405nm, 440–790nm)
High-Sensitivity Detection: 5 detectors (HyD S, HyD X, and HyD R) for optimized photon counting
FALCON & LIGHTNING: Fast lifetime imaging and super-resolution (120nm XY, 200nm Z)
High-Speed Imaging: 22 mm FOV scanner with 10 ps temporal resolution
Recommended Applications:

Advanced Multiplexing: Precise excitation of multiple fluorophores with minimal crosstalk
Functional Imaging:Monitor metabolic states, pH changes, and protein-protein interactions (FLIM-FRET) via TauSense and FALCON
Deep Tissue with High Resolution: Perform high-resolution 3D imaging of thick specimens with LIGHTNING and specialized HyD detectors.

【PolyU develops novel antibody targeting fat cell protein, offering new approach to treating metabolism-related liver cancer】

Liver cancer is one of the three deadliest cancers worldwide, and metabolic dysfunction-related cases have become increasingly common in recent years. A research team led by Prof. Terence LEE, Associate Head and Professor of the PolyU Department of Applied Biology and Chemical Technology has identified an adipocyte-derived protein that promotes cancer growth and has successfully developed a novel antibody that neutralises this protein, marking a significant breakthrough in impeding the progression of liver cancer. The team believes that, as this adipocyte-targeted immunotherapy continues to mature, it will bring more treatment options to MASLD patients.
