(Press-News.org) Cancer continues to be a leading cause of mortality worldwide, highlighting the urgent need to develop more advanced, efficient, and early detection methods. Addressing this critical need, City University of Hong Kong (CityUHK) is leading a groundbreaking research project aimed at developing an innovative technology platform for early detection of cancer and personalised treatment. The project aims specifically to enhance the detection of circulating tumor cells (CTCs), paving the way for significant advancements in cancer diagnosis and care. This is one of the first batch of projects that has secured funding by the RAISe+ Scheme.
The RAISe+ Scheme (the Research, Academic and Industry Sectors One-plus Scheme) is a government scheme launched in October 2023, with a funding allocation of $10 billion, aims to accelerating the transformation of R&D outcomes from “1 to N”, and facilitate relevant collaboration among the government, industries, universities, and research sectors. It provides funding for the transformation and commercialisation of R&D outcomes from local universities, on a matching basis (up to HK$100 million per project).
The project, titled “Microfluidics-Based Detection Platform for Circulating Tumor Cells and Its Applications in Cancer Early Screening and Disease Monitoring”, was awarded, led by Professor Michael Yang Mengsu, Senior Vice-President (Innovation and Enterprise) and Yeung Kin Man Chair Professor of Biomedical Sciences at CityUHK. It aims to develop a next-generation CTC detection platform with enhanced sensitivity and specificity to fulfil clinical needs in cancer early screening, diagnosis and treatment.
Circulating Tumor Cell Testing: Empowering personalised cancer treatment
“Circulating tumor cells (CTC) are tumor cells that circulate in the blood after sloughing off the primary tumor. They carry molecular genetic and cellular information related to the primary tumor,” explained Professor Yang. “Precision diagnosis and comprehensive analysis of CTCs through multi-omics technologies are crucial for cancer early screening, disease monitoring, as well as the development of cell therapies and mRNA vaccines for specific targets and antigens, further supporting the personalised cancer treatment.”
His research team has been focusing on developing biochips and nanotechnology for molecular diagnostics and therapeutics. They have successfully transformed multiple research achievements and co-founded several biotech companies based on CityUHK’s patented technologies, benefiting millions of patients. In 2024, Professor Yang has been elected Fellow of the National Academy of Inventors in recognition of his significant contributions to innovation, societal welfare, and economic development.
Collaboration between Government, Industry, and Academia drives research transformation
CTC can provide valuable information for various clinical applications in tumor detection and treatment, including early screening, diagnostics, treatment selection and efficacy assessment. Owing to limitations in detection technology, however, the full potential of CTCs for cancer disease monitoring and early detection remains to be fully demonstrated. Professor Yang and his research team have founded a biotech company – “Cellomics”, which commercialised the technologies developed in CityUHK into a CTC detection product that has been adopted by more than 50 hospitals in the Mainland China.
With the support of the RAISe+ funding, and in partnership with Cellomics, the team will focus on designing and developing a new platform that will combine microfluidic chip technology with immune-microparticle isolation strategies to efficiently and sensitively screen CTC based on their physical and biological characteristics. “The challenges of CTC detection lie in the low number of CTCs in blood samples, complexity of CTCs and the blood matrix, which requires efficient and specific techniques for their enrichment and characterisation, and to expand CTC-based cultures for further extensive analysis, further to paving the way for personalised cancer vaccines and cell-based treatments,” explained Professor Yang.
Aiming for commercialisation within two years
The team will develop an integrated system that includes an automated CTC sorting instrument, a cell staining device and imaging system, and reagent kits for CTC protein and genetic profiling. These instruments and reagents will comprehensively cover CTC counting, classification, and downstream detection of CTC proteins and genes to enable cancer early screening, diagnostics, drug selection, efficacy assessment, prognosis, and addressing the needs for precision medicine.
“The project is dedicated to establishing and commercialising a CTC detection system for cancer screening and monitoring within the next two years, to increase the early detection rate and improve treatment efficacy and quality of life for patients,” said Professor Yang.

COVID-19 discovery opens door to new treatments for chronic lung problems
2025-03-13
University of Virginia School of Medicine scientists have discovered how severe COVID-19 can destroy immune cells’ ability to repair the lungs, helping explain the lingering effects of long COVID. The findings suggest a new treatment approach for long COVID as well as other conditions, both short-term and chronic, caused by respiratory infections such as the flu.
Led by UVA’s Jie Sun, PhD, the researchers found that severe viral infections including COVID-19 and the flu can gravely damage a key organelle inside immune cells called macrophages. Macrophages direct lung repair after tissue damage, but their ability to do so is crippled ...

New approaches to tackle coupled urban risks: a people-centric and complex systems perspective
2025-03-13
As urbanization surges and climate change intensifies, cities worldwide are facing an increasing number of coupled risks. A recent paper published in Engineering offers fresh insights into understanding and managing these risks.
The complexity of coupled risks in cities, which result from the compounded effects of interacting uncertainties across multiple interdependent objectives, is a major concern. A disruption in one urban subsystem can trigger a chain reaction, affecting other subsystems and leading to unforeseen consequences. For example, the extreme rainfall not only damaged infrastructure ...

Among older adults in Spain, hospitalisation rates from respiratory syncytial virus (RSV) infection increases progressively with age and is more likely among people with other health issues and who live in nursing homes, according to a study published in Eurosurveillance. The hospitalisation rate varied considerably with age and the presence of risk conditions, with important implications for possible targeted interventions.
This population-based cohort study analysed patient data for adults over the age of 60 years in seasons 2016/17 to 2019/20 obtained through electronic medical records ...
Co-authored USF study identifies ‘surprising’ cause of sargassum blooms in Caribbean
2025-03-13
TAMPA, Fla. (March 13, 2025) – The Great Atlantic Sargassum Belt has puzzled researchers since 2011. A recent study published in Nature Communications may have identified what drove a tipping point that established the phenomenon in the tropical Atlantic Ocean.
Using computer modeling, a team of international researchers demonstrated that sargassum blooms were brought to the tropics by strong ocean currents and wind and thrived in ideal growing conditions.
Specifically, two consecutive years of a strong negative North Atlantic Oscillation (NAO), a shift in atmospheric pressure over the Atlantic that changes circulation and wind patterns, pushed sargassum into the tropics starting ...
Statins, aspirin may impact muscle health in smokers
2025-03-13
Miami (March 13, 2025) – For current and former smokers, statins may reduce the amount of chest muscle loss, while aspirin may contribute to increased chest muscle loss, according to a new study. The study is published in the January 2025 issue of Chronic Obstructive Pulmonary Diseases: Journal of the COPD Foundation, a peer-reviewed, open-access journal.
Many people who are current or former smokers are prescribed statins to manage high cholesterol and aspirin to manage heart disease. Research has shown that current or former smokers experience increased skeletal muscle loss, especially in people ...
