“…The optical field of the SPs decays exponentially on both sides of the dielectric/metal interface. Consequently, the SPR phenomenon [ 4 , 9 ] related to the generation of the surface plasmon polaritons (SPPs) and propagation of the surface plasmon wave (SPW) along the dielectric/metal interface, is accompanied by a drop in the reflected intensity [ 4 ], or by a phase change [ 10 , 11 ], and thus it is attractive to sensing in various fields of interest [ 12 , 13 , 14 , 15 , 16 , 17 , 18 , 19 , 20 , 21 , 22 , 23 , 24 , 25 ], especially in biosensing [ 4 , 15 , 16 , 17 , 18 ]. To these measurements, performed in angular or spectral domain, correspond angular or wavelength interrogations.…”

We report on a highly sensitive measurement of the relative humidity (RH) of moist air using both the surface plasmon resonance (SPR) and Bloch surface wave resonance (BSWR). Both resonances are resolved in the Kretschmann configuration when the wavelength interrogation method is utilized. The SPR is revealed for a multilayer plasmonic structure of SF10/Cr/Au, while the BSWR is resolved for a multilayer dielectric structure (MDS) comprising four bilayers of TiO2/SiO2 with a rough termination layer of TiO2. The SPR effect is manifested by a dip in the reflectance of a p-polarized wave, and a shift of the dip with the change in the RH, or equivalently with the change in the refractive index of moist air is revealed, giving a sensitivity in a range of 0.042–0.072 nm/%RH. The BSWR effect is manifested by a dip in the reflectance of the spectral interference of s- and p-polarized waves, which represents an effective approach in resolving the resonance with maximum depth. For the MDS under study, the BSWRs were resolved within two band gaps, and for moist air we obtained sensitivities of 0.021–0.038 nm/%RH and 0.046–0.065 nm/%RH, respectively. We also revealed that the SPR based RH measurement is with the figure of merit (FOM) up to 4.7 × 10−4 %RH−1, while BSWR based measurements have FOMs as high as 3.0 × 10−3 %RH−1 and 1.1 × 10−3 %RH−1, respectively. The obtained spectral interferometry based results demonstrate that the BSWR based sensor employing the available MDS has a similar sensitivity as the SPR based sensor, but outperforms it in the FOM. BSW based sensors employing dielectrics thus represent an effective alternative with a number of advantages, including better mechanical and chemical stability than metal films used in SPR sensing.

“…The existence of limitations owing to a conventional method has urged the development of new alternative approaches towards real-time diagnosis for rapid, sensitive, simple, and convenient to use. Therefore, the exceptional potentiality of biosensors in tuberculosis diagnostics has stimulate an evolution and innovating advanced tools such as surface plasmon resonance (SPR) biosensors [10], piezoelectric biosensors [11], optical biosensor [12], and magnetoelastic biosensors [13]. Despite the reported biosensors which displayed a spectacular performance towards TB detection, its lack of sensitivity is the main considerable concern for its performance particularly to meet criteria setup by World Health Organization (WHO).…”

A novel peptide nuclide acid (PNA) electrochemical biosensor based on reduced graphene oxide (NH2-rGO)/2,2,6,6-tetramethylpiperidin-1-yl)oxyl nanocrystalline cellulose (TEMPO-NCC) for the detection of Mycobacterium tuberculosis (M. Tuberculosis) is described. In this study, the nanohybrid films NH2-rGO/TEMPO-NCC were immobilized onto screen-printed carbon electrode (SPE) via a simple drop-coating method. The electrochemical characterization of the designed electrode was investigated using cyclic voltammetry (CV) and impedance spectroscopy (EIS). Meanwhile, the sensitivity and selectivity of the designed biosensor against M. tuberculosis were measured by the differential pulse voltammetry (DPV). The response of the PNA probe-modified (NH2-rGO)/TEMPO-NCC demonstrated that the fabricated biosensor was able to distinguish between complementary, noncomplementary, and one-base mismatch DNA sequences using methylene blue (MB) as the electrochemical indicator. The developed electrochemical biosensor exhibited a linear calibration curve in the concentration range of 1×10−8 M to 1×10−13 M with the limit of detection of 3.14×10−14 M. The developed electrochemical biosensor has also been tested with a polymerase chain reaction (PCR) product of M. tuberculosis DNA which has shown successful results in distinguishing between negative and positive samples of M. tuberculosis.

“…Thiol-modified ssDNA probes can be immobilized onto Au through covalent interaction and then hybridized with the complementary ssDNA from pathogens to detect using SPR [7]. Hsu et al [8] detected Mycobacterium tuberculosis by using SPR with a sensitivity of -0.087 dB/ (μg/mL) and a highest sensitivity of 115ng/mL. Cheng et al [9] used electrochemically deposited AuNPs on ITO-glass surface for immobilization of specific DNA probe.…”

Nowadays, detection of pathogenic bacteria is one of the major concerns in food, beverage drinking water and pharmaceutical industries. The traditional methods used for identification of bacteria involve detection of characteristic metabolites or cellular reproductive cycles, which is time-consuming, less sensitive, and misleading. From last few decades there has been a great advance in the strategies for detection of pathogenic bacteria by using micro-and nano-fabrication technologies. These technologies largely improved the sensitivity, specificity, limit of detection, and simultaneously reduced the complexity of handing, time and cost of detection. The paper will be focused on newly developed nano-and micro-scaled sensors, microfluidics, lab-on-a-chip, and array based technologies for the detection of different pathogenic bacteria.
