“…We have demonstrated all the above results for the analyte refractive index range from 1.31 to 1.41 because the refractive indices for most bio-uids such as hemoglobin, glucose in the blood, blood plasma, cancer cells, etc., possess in this range [23,26,27,[30][31][32][33]. Therefore, the introduced Fibonacci quasiperiodic PC sensor can be employed for bio-sensing.…”

We present the consequences of different Fibonacci quasiperiodic sequences on the sensing performance of a one-dimensional (1D) photonic crystal (PC) based sensor to detect the blood plasma and cancer cells. We demonstrate that the sensitivity and gure of merit (FOM) of the sensor can be modulated, respectively, from 427.5 nm/RIU to 530 nm/RIU and from 162.5 RIU − 1 to 2983.33 RIU − 1 by utilizing the pertinent sensor structures with Fibonacci generation and structural parameters for the analyte refractive index from 1.31 to 1.41. We have also shown that the operational sensing wavelengths and sensitivity can be changed signi cantly by introducing the different Fibonacci sequences in the proposed sensor. The sensing peaks separation, FWHM, and sensitivity can also be tuned by changing the analyte and PC stacked layers' thicknesses. We also introduce the sensing performances for the Blood plasma and Cancer cells detection using the proposed Fibonacci quasiperiodic PC sensor. We observe that the maximum sensitivities and FOM of the proposed sensor are 552.5 nm/RIU and 2986.93 RIU − 1 for cancer cells and 553.55 nm/RIU and 2214.21 RIU − 1 for blood plasma, respectively. The proposed structure reveals the tunable sensing performances and stimulates the fabrication interest.

“…The presence of the PBG and the ability of PCs to change the spectra position at specific frequencies introduced them as the most interesting and useful materials for sensing applications. Many methods have been developed for the fabrication of highly ordered three-dimensional (3D) PCs [ 11 , 35 , 36 ]. The PBG corresponds to the reflection of light by a periodic arrays and there is no absorbing of light in the process.…”

“…Sensitive bio-sensing technologies such as surface plasmon resonance (SPR), electrochemical biosensors and recently inverse opal photonic crystals (IOPCs) biosensors, have been employed as diagnostic devices for the detection of biomarkers [ [3] , [4] , [5] , [6] , [7] , [8] ]. Photonic crystals (PCs) are dielectric and nanostructured materials with optical sensing properties and wide range applications in the field of optoelectronics and photonics [ [9] , [10] , [11] ]. Presently, PCs biosensors have been used for the selectively and sensitively detection of various biological analytes, such as DNA, cells, pathogens, proteins, antibodies (Ab) allows enhancing sensing performance in terms of limit-of-detection (LOD) [ 12 , 13 ].…”

Photonic crystal (PC)-based inverse opal (IO) arrays are one of the substrates for label-free sensing mechanism. IO-based materials with their advanced and ordered three-dimensional microporous structures have recently found attractive optical sensor and biological applications in the detection of biomolecules like proteins, DNA, viruses, etc. The unique optical and structural properties of IO materials can simplify the improvements in non-destructive optical study capabilities for point of care testing (POCT) used within a wide variety of biosensor research. In this review, which is an interdisciplinary investigation among nanotechnology, biology, chemistry and medical sciences, the recent fabrication methodologies and the main challenges regarding the application of (inverse opals) IOs in terms of their bio-sensing capability are summarized.

“…The forbidden frequency (or wavelength) range is called stop band or photonic band gap (PBG) and arises due to interference of Bragg scattering. Since in the PC propagation of light wave can be controlled and manipulated very effectively, therefore, it has various applications in the field of photonics and optoelectronics [7][8][9][10][11][12][13][14].…”

In this paper, optical reflectance properties of an annular photonic crystal (APC) composed of alternate layers of double negative (DNG) material and a non-magnetized plasma (NMP) layer, immersed in free space, have been theoretically investigated and studied. The reflectance spectra of the annular PC have been obtained by employing the transfer matrix method (TMM) for the cylindrical waves in the case of TEpolarized wave only. It has been found that the spectral position and width of the reflection bands of APC are greatly influenced by the variation in the thickness of DNG metamaterial and NMP layer, respectively. Interestingly, it is observed that the presence of NMP layer causes the increase in photonic band gap (PBG) whereas the DNG layer reduces the PBG. Further, the effect of azimuthal mode number (m) on the reflectance spectra shows that for m > 0, splitting in the reflection bands occurs at the frequency corresponding to the zero permeability value of DNG metamaterial layer. Moreover, with the increase in azimuthal mode number one PBG is red-shifted and the second one is blue-shifted. Finally, the effect of change in the starting radius parameter of curved surface and plasma electron density on the reflectance spectra of APC has also been studied and very interesting results have been observed.
