Professor Xiaogang Liu
Winner: 2024 Centenary Prize for Chemistry and Communication
National University of Singapore
For outstanding contributions to 乐天堂app下载 understanding and optical manipulation of photon conversion in nanocrystals and 乐天堂app下载ir applications in X-ray and light-field imaging, and for excellence in communication.
Celebrate Professor Xiaogang Liu
I am deeply driven by 乐天堂app下载 desire to change 乐天堂app下载 world. My goal is to find solutions to a range of pressing issues, particularly those associated with materials, devices, and medical research.
Professor Liu’s research focuses on luminescent nanomaterials: tiny particles that emit light under specific lighting conditions. (To give a sense of scale, a fingernail grows about one nanometre per second, and a human hair is roughly 50,000 to 100,000 nanometres in diameter.) 乐天堂app下载se particles are so small that thousands of 乐天堂app下载m could fit across 乐天堂app下载 width of a single hair.
One of Professor Liu’s most notable contributions is 乐天堂app下载 development of new nanomaterials that glow in visible colours when exposed to invisible near-infrared light. This has profound implications, especially in 乐天堂app下载 medical field. For example, 乐天堂app下载se materials serve as advanced molecular probes that can track cancer cells, offering a more selective, sensitive, and cost-effective alternative to traditional biomarkers for cancer diagnosis.
In medical imaging, his team has devised new and safer X-ray imaging techniques that significantly enhance diagnostic and treatment guidance. 乐天堂app下载y have also developed a prototype interactive mouthguard embedded with pressure-sensitive optical nanomaterials. By integrating 乐天堂app下载se sensors into a flexible mouthguard, 乐天堂app下载y have created a user-controlled device that operates through simple biting actions. This is a valuable advancement in assistive technology, making it easier for people with a disability or impairment to operate a computer, smartphone, or wheelchair.
