چکیده
In this work, we propose a surface plasmon resonance (SPR) biosensor based on hybrid structure of silicon nitride (Si3N4), molybdenum trioxide (MoO3), and graphene oxide (GO) in the Kretschmann configuration. To investigate performance parameters SPR biosensor, calculate, theoretically, reflectance spectra proposed model analysed it. The investigation various i.e., sensitivity, detection accuracy, quality factor, sensor configuration are theoretically done with optimized thickness silver (55 nm), (5 (10 (2.55 nm) respectively. figure merit for found at 301 deg./RIU, 4.01, 133 RIU−1 respectively IgG. Furthermore, present shows improved sensitivity as compared to other reported works. refractive index analyte changes from 1.33 1.37 due adsorption GO surface. design can detect small change sensing media doped analyte.

Sensitivity Enhancement of Magneto-Optical Surface Plasmon Resonance (MOSPR) Biosensor
We present the optimization of a new material structure used as transducer in a MagnetoOptical Surface Plasmon Resonance (MOSPR) biosensor. The MOSPR sensor is a modification of the standard Surface Plasmon Resonance (SPR) biosensor, which arises from the introduction of a ferromagnetic metal layer with Magneto-Optical (MO) activity together with the usual gold layer of SPR biosensors. Such com...
متن کاملStreptavidin-enhanced surface plasmon resonance biosensor for highly sensitive and specific detection of microRNA
We are presenting a method for sensitive and specific detection of microRNA (miRNA) using surface plasmon resonance. A thiolated capture DNA probe with a short complete complementary sequence was immobilized on the gold surface of the sensor to recognize the part sequence of target miRNA, and then an oligonucleotide probe linked to streptavidin was employed to bind the another section of the ta...
متن کاملEnhanced sensitivity of surface plasmon resonance phase-interrogation biosensor by using oblique deposited silver nanorods
Sensitivity of surface plasmon resonance phase-interrogation biosensor is demonstrated to be enhanced by oblique deposited silver nanorods. Silver nanorods are thermally deposited on silver nanothin film by oblique angle deposition (OAD). The length of the nanorods can be tuned by controlling the deposition parameters of thermal deposition. By measuring the phase difference between the p and s ...
متن کاملDetection of Carcinoembryonic Antigens Using a Surface Plasmon Resonance Biosensor
Carcinoembryonic antigen (CEA) is an oncofoetal cell-surface glycoprotein that serves as an important tumor marker for colorectal and some other carcinomas. In this work, a CEA immunoassay using a surface plasmon resonance (SPR) biosensor has been developed. SPR could provide label-free, real-time detection with high sensitivity, though its ability to detect CEA in human serum was highly depend...
