Professor Chester Shu, Professor and Chair of the Department of Electronic Engineering of The Chinese University of Hong Kong (CUHK), has been elected a Fellow of 2022 by Optica, a prestigious international society in the field of optics, in recognition of his seminal contributions to effective control and processing of optical signals in communications. This year, 106 members from 24 countries/districts have been elected to the Fellow Class for their distinguished contributions to education, research, engineering, business and serving the community. The number elected each year is limited to approximately 0.5% of the current membership.
 
Professor Shu remarked, “I am greatly honoured to be elected an Optica Fellow in appreciation of our research on optical communications performed at CUHK. Our achievement would not have been possible without the tremendous support from the University, the concerted effort in creating a collaborative research environment, and the strong dedication of our team members to photonics research. We are indebted to visionary founders of the field, namely the late Professor Charles Kao, former Vice-Chancellor and President of CUHK who brought light to the path that we now tread and venture forth.”
 
In today’s communications, massive information is carried by optical waves that are transmitted at the speed of light. The processing of optical signals with the conventional approach is however limited by the high power consumption and large latency. These challenges can be addressed by controlling and processing the signals in the optical domain. It is envisaged that with the integration of optical and electronic technologies, unprecedented performance can be achieved by fully utilising the available bandwidth, power and other resources in an optical communication system, while offering transparency, tunability, and reconfigurability in processing the signals.
 
Professor Shu joined CUHK in 1992 and his major research interest is in multi-dimensional processing of light waves for advanced communication systems. His research group has made notable contributions in decoupling the amplitude and phase responses of optical signals, breaking a major constraint that hinders wider applications of the processing approaches. Professor Shu is a subject editor-in-chief of IET Electronics Letters and a senior editor of IEEE Photonics Journal, both in the realm of optical communications.
 
Optica, formerly known as The Optical Society (OSA), is a world leading champion for optics and photonics established in 1916. It aims to advance optics and photonics worldwide, and deliver high-quality scientific and technical information that is authoritative, accessible and archived. Optica unites and serves 432,000 scientists, engineers, educators, technicians and business leaders worldwide from 181 countries/districts.

Professor Raymond Tong, Chairman of the Department of Biomedical Engineering at The Chinese University of Hong Kong (CUHK) and inventor of the exoskeleton robotic hand for stroke rehabilitation “Hand of Hope”, has been honoured with the “Global Ageing Influencers 2021” award at the 9th Asia Pacific Eldercare Innovation Awards Ceremony held by the Ageing Asia in Singapore, in recognition of his outstanding achievements in rehabilitation innovations, programmes and services that advance the standard of living for older adults on a global scale.
 
Professor Tong is the only winner of the “Global Ageing Influencers 2021” from Hong Kong. The other 9 awardees are from Singapore, Australia, the United Kingdom, New Zealand, Thailand, Indonesia and mainland China. On the same occasion, the “HOPE 4 Care” programme led by Professor Tong’s biomedical engineering research team and the Faculty of Medicine, CUHK, took home the “Best Rehabilitation Programme” award.
 
“I am most thankful and humbled to be recognised as one of the ‘Global Ageing Influencers 2021’ with some of the world’s most prominent professionals and scholars in the field of ageing,’ said Professor Tong. “Talented minds and the innovative solutions that emerged from interdisciplinary and cross-boundary collaborations are required to tackle the global challenge of ageing population. Through ‘HOPE 4 Care’, which runs on a partnership between CUHK research teams and dozens of community centres in Hong Kong, we demonstrated how novel rehabilitation equipment and technology can be beneficial in supporting and accelerating the recovery of stroke patients. This programme is particularly impactful amid the global pandemic since patients can receive guided training at home. The effort by each of my team members and partnering organisations has affected the life of many patients in the best possible way and I sincerely appreciate their work.”.
 
The “Hand of Hope” mechanical robotic hand rehabilitation system, developed in 2012, can detect and amplify signals that the brain is sending to patients’ hand muscles and pass the information to the robotic hand. This enables patients to learn again the correct way of using the brain to control their hand functions. The “Hand of Hope” was the first Hong Kong-based innovation to receive the Grand Prix Award at the International Exhibition of Inventions of Geneva. Making use of the latest 3D silicone printing technology, a new version of the soft robotic hand was later developed, providing stroke patients with a tailor-made, less bulky but comfortable and affordable device for the rehabilitation process.
 
The “Hand of Hope” forms part of CUHK’s “Hope 4 Care” programme, which is a joint initiative from the Department of Biomedical Engineering and the CUHK Faculty of Medicine focused on combining software and robotic technologies with clinical expertise to enhance rehabilitation outcomes for stroke patients. The programme is generously funded with support from The Hong Kong Jockey Club.  
 
About the Asia Pacific Eldercare Innovation Awards
 
Launched in 2013, the Asia Pacific Eldercare Innovation Awards, the first of its kind in the Asia Pacific, was created by Ageing Asia to provide an annual recognition to individuals and organisations in Asia Pacific regions that demonstrate eldercare innovation to change the way seniors age. Previous awardees of the “Global Ageing Influencers” include Dr LAM Ching-choi, non-official member of the Executive Council of the Government of the Hong Kong Special Administrative Region and Chairman of the Elderly Commission, Hong Kong.

CUHK researchers develop novel gold nanoparticle as alternative treatment for psoriasis

Date: 
2021-12-08
Thumbnail: 
Body: 
Professor Jonathan Chung Hang CHOI, Associate Professor of the Department of Biomedical Engineering of the Faculty of Engineering at The Chinese University of Hong Kong (CUHK), and his team have developed a new gold nanoparticle as a self-therapeutic treatment for psoriasis. Devoid of steroids or biologics, this gold nanoparticle can downregulate the genes that are linked to epidermis hyperproliferation and inflammation and is an effective treatment for psoriasis. Based on data from mouse disease models, it treats psoriasis as effectively as a standard topical steroid and vitamin D analog-based therapy but without causing hair loss, skin wrinkling, or other side effects, therefore offering a simple, safe and effective alternative for treating psoriasis. The research findings have been recently published in Nano Letters. 
 
Psoriasis is a chronic, non-communicable inflammatory disease, characterised by red patches, and thick and silvery scales in the skin. Over 125 million people worldwide (approximately 2-3% of the population) suffer from psoriasis. Currently, there is no specific cure, and available treatment modalities have different side effects. For example, systemic administration of immunosuppressants may induce liver and kidney toxicity, topical application of steroids and vitamin D analogs may cause skin irritation, and ultraviolet light phototherapy may lead to skin cancer. Emerging biologics are costly and associated with an enhanced risk of infection. Psoriasis imposes a psychological and financial burden on patients, significantly reducing their quality of life. 
 
Bypassing the bottleneck for drug delivery to skin cells
 
Researchers in the field have developed nanoparticles to load drugs, such as steroid or biologics for improving their delivery to the skin and reducing their toxicity, yet these drugs may not enter skin cells and accumulate in the skin for a sustained efficacy. Professor Choi and his team have designed a new class of nanoparticle, smaller than 15 nm in overall diameter, that bears a 3 nm gold core and an outer shell of polyethylene glycol strands modified with octadecyl chains. The polyethylene glycol shell prevents the gold cores from sweat-induced aggregation that disfavors their permeation to the epidermis, and the octadecyl chains promote the entry of the gold cores to the epidermal keratinocytes. After mixing the new nanoparticles with saline, the soaking gauze with nanoparticle solution was applied onto the psoriatic skin of mice for topical delivery. These nanoparticles successfully cross the thickened scales in the stratum corneum and then enter epidermal keratinocytes. Such a nano-material structure bypasses the bottleneck for drug delivery to skin cells.
 
Direct application of gold nanoparticles for treating psoriasis and inhibiting psoriasis-related genes
 
It has been revealed by many studies that the interleukin-17 signaling pathway is critical to the induction of psoriasis. The findings of Professor Choi’s team showed that the application of this new gold nanoparticle during the induction of psoriasis can prevent this disease and suppress genes in relation to the interleukin-17 signaling pathway. Applying this new gold nanoparticle after psoriasis is established can lead to obvious improvement in skin condition and reduced scales, with an efficacy similar to standard steroid and vitamin D analog-based therapy, but without inducing common side effects such as hair loss and skin wrinkling. For the first time, this study reveals the self-therapeutic value of gold nanoparticles in treating psoriasis, obviating the need for loading steroids or biologics. In addition, this new nanoparticle does not accumulate in major organs, nor does it cause long-term toxicity in skin and body.
 
Professor Choi said, “We hope to continue our collaboration with the Faculty of Medicine at the University and perform clinical studies to validate the safety and efficacy of this new gold nanoparticle in humans in the future, so as to offer a new, safe and effective treatment for psoriasis patients. Moreover, our data indicates that this nanoparticle can downregulate multiple genes that are related to skin inflammation. We will explore its therapeutic potential for other skin diseases, such as the more prevalent eczema.”
 
Other team members from CUHK include Ms. Alisa Ruifang HAN, PhD student of the Department of Biomedical Engineering of the Faculty of Engineering, Professor Paul Cheung Lung CHOI, Honorary Clinical Associate Professor of the Department of Anatomical and Cellular Pathology of the Faculty of Medicine, and other researchers from the University. This project received support from the Research Grants Council of Hong Kong, the CUHK Vice-Chancellor Discretionary Fund, Chow Yuk Ho Technology Centre for Innovative Medicine, and the Croucher Innovation Award by the Croucher Foundation.
