Microcantilevered MEMS Biosensor for Detection of Malaria Protozoan Parasites

In this paper, the presented work aims to provide a designed model based on Finite element method for detection of Malaria protozoan parasites. Microcantilevers are next generation highly efficient biosensors for detection and prevention of any disease. Here, an Eshaped model for micro cantilevered biosensor is designed using COMSOL Multiphysics specifically for detection of Malaria. Microcantilever materials viz Au, Cu, Si and Pt are used for sensing Malaria protozoan with proper optimization of device structure. The studies were carried out for stress developed and displacement occurred due to force applied through these protozoan biomolecules and varying beam length. Further, the designed structure was analyzed for different beam materials available for biosensor and it was found that Au is best suitable material for detection of malaria protozoan parasites since it has best sensitivity profile among presented materials. The results were also verified through analytical approach and it was found that both results obtained through simulation and analytical methods do closely agree with each other.
