Project Description

The Project
Infectious diseases are major public-health problem all over the world. Nanomaterials exhibit unique optical properties that are important in biosensor development. For diagnosis, nanosensors have great potential for on-site rapid detection, with the remaining challenges to be overcome, for example, ultrahigh sensitivity requirement for known analytes such as Dengue NS1, and low cost for home testing. This project aims to address these challenges, focusing on the development of plasmonic shaped variant nanoparticle-based sensing techniques.

The scopes include (1) developing highly sensitive plasmonic nanostructures through bottom up synthesis, coupled with biomarkers for Dengue NS1. We will identify the appropriate antibody/antigen pairs for different diagnostic tests (clinical management of diseases, or for monitoring and surveillance or home testing); (2) studying photochromic property for sensing; (3) engineering the sensors for on-site application including using portable optical detectors and printing the metal structures onto low-cost paper format. (4) Testing sensors for against the library of samples.
