The ability to precisely control the structure and the function of synthetic materials has profound significance for many researchers because molecule level designs are critical to regulating the properties and functions of biomaterials at various scales. In conventional methods, single chain polymeric nano particles or nano gels are generally produced under highly dilute conditions or with low monomer conversion rates, which severely hinder the widespread applications of single chain nano objects.
The novel method showcases the wide application of such materials in biomedical engineering. One example is in gene or drug delivery and regulation of stem cells behaviour in nano scale. At the same time, this advanced nano material can realise the effective protection of stem cells and regulation of cell behaviour, which is of great significance in stem cell therapy, stem cell tissue engineering application and scientific research. Professor Bian said, “This research provides a strong basis for designing and applying the new materials in daily activities. The findings enable the large scale production and translation of single chain polymeric nanomaterials, which could only be produced in limited yield by conventional methods in the past, to a wide array of applications such as biomedicine, catalysis, and biosensing. The scale-up prepared single chain polymeric nanomaterials can also be a valuable tool to assist fundamental researches.”
Professor Bian began individual research work in CUHK in 2013. He has been committed to the development of advanced nano materials and hydrogel materials in the area of biomedical applications and gradually established in-depth research, from basic materials science and biomedicine to medical application. Graduate students and post-doctoral researchers supervised by Professor Bian have received many prestigious awards for their excellent research work. The project was supported by the Research Grants Council of Hong Kong, HKSAR Government Food and Health Bureau’s Health and Medical Research Fund, National Science Foundation of China, Innovation and Technology Commission’s Innovation Technology Fund and Chow Yuk Ho Technology Centre for Innovative Medicine.
