Background: In the present research work we have examined the biosensing capabilities of one-dimensional photonic crystal with defect suitable for detection and sensing of malaria inflection by means of investigating samples containing red blood cells. This theoretical work is based on transfer matrix formulation in addition to MATLAB software under normal incidence condition due to several difficulties associated with oblique incidence. We have evaluated the performance by taking random cavity thicknesses of 1000 nm, 2200 nm, 3000 nm and 5000 nm to estimate the cavity thickness suitable for optimum performance of the proposed biosensing design. The optimization of cavity is one of the most necessary requirements because it decides the minimum volume requirement of the blood sample for getting results of high accuracy. Moreover sensing and detection capabilities of the proposed design has been evaluated by examining the sensitivity, figure of merit and quality factor values of the design corresponding to optimum cavity thickness.
