Prof. HE Mingguang discusses non-invasive angiography on TV programme

Prof. HE Mingguang, Director of Research Centre for SHARP Vision (RCSV), Henry G. Leong Professor in Elderly Vision Health and Chair Professor of Experimental Ophthalmology of the PolyU School of Optometry, appeared on the HOY TV’s programme “Health Concern Group” on 1 October 2025, sharing the application of non-invasive angiography in ophthalmic diagnosis. Prof. He pointed out that traditional fundus fluorescein angiography requires the injection of a contrast agent into the patient’s vein, a process that is not only time-consuming and costly, but also potentially life-threatening.  To address this, Prof. He and his team have utilised Generative AI technology to convert ordinary fundus photographs into high-precision angiographic images and dynamic videos within seconds, thereby effectively identifying ophthalmic diseases such as early diabetic retinopathy, central serous retinopathy, and retinal vascular damage caused by hypertension.   Online coverage: HOY TV - https://polyu.me/4pOGCWH (07:17 - 11:13)

Prof. Nathanael JIN Ling’s study reveals public health risks of drug-resistant Candida in cities

Prof. Nathanael JIN Ling, Member of the Research Institute for Future Food (RiFood), the Research Institute for Sustainable Urban Development (RISUD) and the Mental Health Research Centre (MHRC), and Assistant Professor in the Department of Civil and Environmental Engineering and the Department of Health Technology and Informatics, has recently published a pioneering research in Environmental Science & Technology Letters, shedding light on the public health risks posed by airborne Candida species in densely populated urban areas. The key findings of the study are as follows: • Drug-Resistant Candida in Urban Air: The study detected viable, drug-resistant strains of Candida parapsilosis, Candida albicans, and Candida tropicalis in city air samples—strains that were notably absent in coastal environments. • Genetic Similarity to Clinical Strains: Airborne isolates exhibited a high degree of genetic similarity to those found in clinical settings, suggesting that community-acquired infections could occur through inhalation or skin contact. • Multidrug Resistance: Of particular concern was the discovery of multidrug resistance in C. parapsilosis, raising questions about the role of urban pollution and climate change in driving antifungal resistance. Candida species are classified as WHO fungal priority pathogens due to their severe health impacts.  Prof. Jin’s research highlights the urgent need to recognise urban air as a significant medium for the spread of antifungal-resistant strains.  Looking ahead, his research team plans to expand their work to larger, multi-site studies to better understand fungal transmission pathways, investigate urban reservoirs of drug-resistant fungi and strengthen One Health approach to combat the global threat of fungal resistance.

Prof. NI Meng co-authors paper on enhancing the durability of high-temperature ceramic fuel cells in Nature Communications

Prof. NI Meng, Associate Dean of Faculty of Construction and Environment, Head of Department of Building Environment and Energy Engineering and Chair Professor of Energy Science and Technology of PolyU, in collaboration with researchers from Shenzhen University, The Hong Kong University of Science and Technology, Nanjing Tech University and Curtin University, published a paper titled “Interfacial oxide wedging for mechanical-robust electrode in high-temperature ceramic cells” in Nature Communications recently. Delamination and cracking of air electrodes are two mechanical factors contributing to the degradation of high-temperature electrochemical ceramic cells.  While the incorporation of negative thermal expansion (NTE) materials can address delamination by reducing the thermal expansion coefficient (TEC) of the air electrode, it may exacerbate cracking due to significant thermal stress between particles of NTE and positive thermal expansion perovskites (PTE).  The research team has introduced interfacial oxides to “wedge” the NTE-PTE interface, thereby resisting cracking within the bulk of the air electrode through reactive calcination at near-melting temperatures. The study demonstrated that that oxide wedging, which utilises the thermal expansion offset provided by a NTE component to greatly enhance interface multiphase binding, can serve as an effective strategy for developing mechanically robust electrodes for high-temperature electrochemical cells.  Enhanced bulk modulus (by 102%), hardness (by 138%), and reduced TEC (by 35%) are simultaneously achieved, significantly improving the durability of the air electrode over 40 rigorous thermal cycles between 600 °C and 300 °C, with no degradation observed even after two years of exposure to ambient air. Prof. NI Meng is currently Management Committee Member of Otto Poon Charitable Foundation Research Institute for Smart Energy (RISE) and Member of Research Institute for Sustainable Urban Development (RISUD).

Unlocking brain signals: Prof. George Malliaras explores frontiers of electrophysiology in PAIR Distinguished Lecture

Recent advances in cortical and cutaneous electrophysiological recordings are rapidly expanding our ability to decode neural information.  On 30 September 2025, Prof. George MALLIARAS from University of Cambridge, United Kingdom, delivered a PAIR Distinguished Lecture titled “How Much Can We Learn from Cortical and Cutaneous Electrophysiology?”  He shared insights into the recent studies that explore the boundaries of cortical and cutaneous electrophysiology.  The lecture attracted nearly 100 in-person attendees, with more than 13,500 online viewers tuning in via various social media platforms. At the outset of his talk, Prof. Malliaras provided a brief overview of modern bioelectronic medicine applications, ranging from cardiac pacemakers for arrythmias in the 1960s to the nerve stimulators for autoimmune diseases in the 2010s, and highlighted their limitations.  He then introduced his team’s research achievements and potential applications in the field, including brain-computer interfaces, spinal cord cuffs, neurostimulator, cortical recording and stimulation, peripheral nerve cuffs, body surface potential mapping and e-textile.   In summary, Prof. Malliaras emphasised the inherent trade-off between invasiveness and resolution exists in electrophysiology.  Thin-film electrodes enable circumferential recording and stimulation of the spinal cord, paving the way for a novel spinal cord injury bypass and allowing for the prediction of movement kinematics.  Peripheral nerve cuffs facilitate sub-nerve recording and stimulation, offering new possibilities for organ function restoration.  Body surface potential mapping provides a wealth of information and has been validated by studies involving dogs with valvular heart disease.  These technologies together allow us to decode a broad range of signals, supporting applications in neuroprosthetics and health monitoring. Ongoing innovations in materials and interface engineering continue to enhance the amount and quality of information extracted from the brain and body. The subsequent question-and-answer session was chaired by Prof. YAN Feng, Associate Director of Research Institute for Intelligent Wearable Systems (RI-IWEAR) and Chair Professor of Organic Electronics.  Both in-person and online audiences engaged in fruitful exchanges and discussions with the two professors.
