Nanoplatform development for ultrasensitive lateral flow assays

​Lateral flow assays (LFA) are paper-based simple devices for a variety of point-of-care testing, for example the home pregnancy assay. However, the poor sensitivity has limited their applications in quantitative analysis of low-abundant biomarkers. The use of quantum dots (QDs) with high fluorescence quantum yield and high stability to replace gold nanoparticles used in conventional LFA represents a promising approach to improve the sensitivity of LFA. Fang is focusing on the development of advanced LFA with improved detection sensitivity in applications such as early diagnosis based on the nanoporous particles-assisted signal amplification of QDs.

​Prior to joining UQ in 2018, Fang completed her Master of Medicine in Pharmaceutical Science from South-Central University for Nationalities and her Bachelor of Engineering in Pharmaceutical Engineering from Hubei University of Chinese Medicine.
