In the proposed work, the detection of hemoglobin has been carried out using an SPR
biosensor. The detection of hemoglobin is necessary because excessive concentration can
cause severe disorders like anemia or polycythemia. The proposed device can detect
hemoglobin concentration in blood samples. The performance of the proposed biosensor is
numerically analyzed using the angle interrogation method. A hemoglobin increment of
6.1025 g/L caused by a refractive index increment of 0.001 in the blood samples in the …

In this paper, the performance of graphene and MXene employed SPR biosensor is
numerically analyzed using angle interrogation to detect hemoglobin in blood samples. A
hemoglobin increment of 6.1025 g/L caused by a refractive index increment of 0.001 in the
blood samples present in the sensing medium, which has been detected using an SPR
biosensor. The proposed configuration consists of six components: BK7 prism, bimetallic
silver layers (45 nm and 7 nm), MXene and graphene layers, along with sensing medium to …
