“…Since the detection of the microplastics in water is intricate due to the aforementioned properties, a compact europium-aluminium (Eu-Al) doped polymer optical planar waveguide sensor, fabricated by using a micro-dispenser machine may be necessary to ascertain the presence of transparent and translucent microplastics in water. This is based on the fact that an optical polymer planar waveguide has superior properties [3][4][5][6], which include strong evanescent elds [7][8][9], highly exible, small and compact, and cost-effective manufacturing for large scale production especially through the Mosquito method [10][11][12][13]. Aside from that, the europium-aluminium doped polymer exhibits sharp red emission at 617 nm with high brightness and intensity [2,14,15].…”

Nowadays, microplastics pollution has become a global concern as it endangers the ecology and marine animals and causes health threats to human beings. This paper demonstrated a simulation of an optical planar waveguide sensor design for microplastics detection in water via Wave Optics Module-COMSOL Multiphysics®. The design optimisation of the sensor was conducted by changing the cladding thickness ranging from 0 to 5 µm. The change in analyte refractive index ranging from 1.480 to 1.500 refractive index unit (RIU) in reference to the microplastics’ refractive index has been performed to evaluate the simulated sensing performance. The simulation results showed that reducing the cladding thickness can vastly improve the sensor sensitivity. The sensor showed the highest sensitivity in the absence of cladding layer i.e.; the cladding thickness of 0 µm with 107 difference in the order of magnitude of sensitivity compared to that of 5-µm thickness. Thus, the optimised sensor design with 0 µm cladding thickness assures an excellent sensor for microplastics detection in water.
