Early detection of chikungunya virus disease is critical for effective management of the disease. This study focused on developing the performance of a refractive index detector based on a photonic crystal biosensor that can quickly and accurately detect virus-infected blood and urine components. A geometrical study was performed to improve the sensitivity in which a very high value of 973.24 um/RIU has been reached. In this article we have proposed a 2D photonic crystal structure biosensor to detect the influence of chikungunya virus on blood components and uric acid. After a geometric study, we found a performance parameter that led to achieve a very high sensitivity of 973.24 m a transmission efficiency of 68.42 % and aquality factor of 695.18.
