About the Project

Background

Human tear fluid is characterized with a tiny volume and complex compositions of proteins and other biomolecules, which may be useful to monitor not only ocular but also many systemic diseases. Although tear can be collected with minimally invasive procedures nowadays, these procedures are tedious and inconvenient, which also create discomfort to the patients, making disease monitoring using tear samples less promising and clinically translational. In addition, tear analysis is technically challenging because of the small volume of tear fluid (<5 μL) available, which the amount of the potential biomarkers is too low to be detected by current molecular diagnostic methods. Therefore, before tear can be used as a reliable source of liquid biopsy, improved tear collection methods and standard tear handling procedures with sensitive and reliable proteomic analysis technologies are all required.

 

Objectives and Significance

We aim to build a point-of-care contact-lens based device which can conveniently and efficiently collect tears, followed by performing sensitive molecule diagnosis on the device with simple procedures. The success of this proposed project will lead to a better use of tear for disease diagnosis, in terms of providing a detection with higher sensitivity and lower diagnostic cost, and a relative safer and more comfort tear collection experience.

 

Requirements

We are recruiting students at all levels (RPg, MRes[Med] and URIS) for this project. RPg students with experience in microfabrication and biomolecule sensing would have advantages. Undergraduate students in the LKS Faculty of Medicine, HKU with strong interests in biomedical engineering are welcome to apply for MRes[Med] and URIS.
