This paper presents a 2D photonic crystal based biosensor for numerical refractive index sensing related to pancreatic cancer. The development of pancreatic cancer begins with DNA mutations in pancreatic cells, which result in incorrect instructions enabling the cells to grow uncontrollably. As sensing devices, biosensors exhibit rapid and sensitive measurements. Therefore, they are widely used in the medical field for quick and accurate disease diagnosis. Photonic crystal biosensors are made to identify diseases like cancer, malaria and tuberculosis and others. Photonic crystal biosensors operate on the basis of a shift in the peak resonance wavelength that corresponds to minute variations in the refractive index values. A photonic biosensor has a high sensitivity and can provide results quickly. The variations in refractive index between normal and abnormal biological conditions can result in a shift in the resonance wavelength. The simulation and analysis of the design have been done using the Finite Difference Time Domain (FDTD) method.

Active accounts were imported to the new platform and assigned a random password by default. In order to access your account you need to access the login page and go through the Lost Password dialog (involves the system sending you an email with instructions) in order to reset your password. This step is necessary as passwords are kept in hashed form and the new platform uses modern hashing algorithms incompatible with the previous ones.
