Fe3O4 nanofluid injected photonic crystal fiber for magnetic field sensing applications

Optical Properties of Fe3O4/Chitosan and Its Applications for Signal Amplifier in Surface Plasmon Resonance Sensor

“…The Fe3O4 nanoparticle has been used widely as active material in many types of the sensor due to their active and high surface area to volume ratio [7], high electron exchange rate [8], excellent adsorption, and inherent electrical conductivity [9]. Those sensors are electrochemical sensors [7,[9][10][11], magnetic sensors [11][12][13][14], and optical sensors, such as surface plasmon resonance (SPR) based sensor [15][16][17]. The SPR-based sensor is commonly regarded as Otto and Kretschmann configuration.…”

Design of Honeycomb Shaped Spectroscopy based Biosensor for the Detection of Tuberculosis Cells

“…As the proposed sensor is a single mode fiber sensor, so the core mode of the fiber structure can be obtained for the two polarization modes [22]. The arrow sign indicates the direction of the polarizations.…”

Terahertz chiral sensing and magneto-optical enhancement for ferromagnetic nanofluids in the chiral metasurface

“…Ferromagnetic nanofluid is a colloidal suspension composed of magnetic nanoparticles in a carrier liquid, which has a significant advantage due to its liquid form and weak magnetic field requirement, especially in liquid-filled photonic devices 24,25 . Shalaby et.…”

“…Ferromagnetic nanofluid is a colloidal suspension composed of magnetic nanoparticles in a carrier liquid, which has a significant advantage due to its liquid form and weak magnetic field requirement, especially in liquid-filled photonic devices. 24,25 Shalaby et al demonstrated that the magnetic nanofluid has a weak Faraday rotation in the THz regime, but is not adequate for a THz Faraday isolator. 26,27 Therefore, the limitation for developing a THz magneto-optical device is mainly the lack of materials with strong magneto-optical activity and low loss in the THz regime.…”
