Feasibility study of long period grating as an optical biosensor for dengue virus detection - an alternative approach to dengue virus screening

Dengue being one of the current global epidemic diseases currently is mainly found in tropical and large swamp areas. A fast diagnostic method is required to give an accurate result of a suspected dengue patient in order to save lives. Long period grating -LPG (or sometimes known as long period fibre grating-LPFG) has a fast detection method almost to real time gives an immediate result and it is highly sensitive towards its ambient refractive index. Long period grating is a modified fibre optic with grating at a specific portion of the optical fibre; the fibre optics signal transmission does not decay easily and remains almost ideal for all application. This paper aims to study an alternative approach to screen patient who are suspected with dengue and results obtained will be used as a future guideline for subsequent research.
