Malaria biosensors with ultra-sensitivity and quality factor based on cavity photonic crystal designs

According to the World Health Organization, Malaria is still a dangerous disease. Efforts to discover and cure it are widely required. In this work, 2D photonic crystal (PhC) biomedical sensors based on the index of refraction are designed, simulated, and evaluated. The target is to propose two designs to detect effective stages of Malaria. The first design can be fabricated based on today's technology, and it has remarkable sensitivity with reasonable quality factors and compactness with size 11.4 x 9.2 mu m(2). The second one requires advanced fabrication techniques, but it has ultra-quality factors with reasonable sensitivity and compactness with size 9.4 x 5.5 mu m(2). The operating wavelength for both structures is 1.55 mu m. These performance indicators exceed corresponding levels in all literature discusses Malaria detectors. A comparison between the presented work and others based on several technologies is carried to prove the validity and effectiveness of the proposed designs.
