The Faculty of Engineering at The Chinese University of Hong Kong (CUHK) will hold its 20th Anniversary Innovation and Technology Fair from 16 to 18 September on campus to showcase to the public an extensive collection of the latest innovative research projects in engineering and information technology conducted by its faculty members and students. The advanced technology in automated and continuous monitoring of an air pollutant, polycyclic aromatic hydrocarbon (PAH), is one of the accomplishments. A research team led by Professor Douglas Yung Pun-to of the Department of Electronic Engineering has developed the molecularly imprinted polymer (MIP) technique to specifically detect various types of airborne PAHs through the use of a miniaturized sensor, and is designing a portable and field-deployable monitoring device for airborne polycyclic aromatic hydrocarbons to allow measurement without geographical limitation. With lower testing cost, shorter time and greater convenience compared with traditional measurement methods, this technology will help government departments, consulting firms, factories and manufacturing plants to perform more effective monitoring of air quality, thereby enhancing air quality and safeguarding health.
