RESEARCH HIGHLIGHTS:

Research on food, water and environmental contaminations is critically important. Current experimental and laboratory techniques in Malaysia to obtain evidence of the contamination are not sufficient. Clearly, monitoring of the chemical load in the environment is vital for safety and activity in this area will only increase in the coming years. In IMEN, our Organic and Printed Electronic Group work on the detection of organic pollutants in agriculture and environment, water and food contaminations and analysis of biological molecules due to their toxicity, persistence, long-range transport ability and bioaccumulation.

Based on our analytical technique in optical engineering, we produce rapid and accurate detection of a plasmonic device using nanotechnology. However, there are considerable challenges in the areas of producing ultimate sensitivity which depend directly on the quality of the nanomaterials used as a sensing material. Therefore, we have been aspiring to explore nanomaterials such as noble metal, metal oxide, 2D materials and other transition metal dichalcogenides which are potentially applied as a highly sensitive detector in localized surface plasmon resonance (LSPR) and surface-enhanced Raman scattering (SERS).
