This paper reviews Kretschmann-based SPR sensor utilizing ZnO thin films and nanostructures for performance enhancement. The advancement in surface plasmon resonance technology relies on low-cost, high sensitivity and high selectivity sensor. Metal oxide has been incorporated in SPR sensor to be used for detection of biological and chemical compounds. ZnO as one of the metal oxides is an attractive material due to its unique physical and optical properties. Numerous techniques for fabrication and characterization of ZnO on SPR gold substrate have been studied. The mechanism for gas and biomolecules detection depends on their interaction with ZnO surface, which is mainly attributed to the high isoelectric point of ZnO. There are several types of ZnO nanostructures which have been employed for SPR application based on the Kretschmann configuration. In future, the thin film and nanostructures of ZnO have potential applications for miniature design, robust, high sensitivity, and low-cost portable type of SPR biosensor to be used for on-site testing in real-time and label-free manner.

“…29 When the noble metal nanoparticles are combined with ZnO, under the effect of SPR, the excited electrons in the noble metal nanoparticles can accumulate at the interface, leading to downward band bending of ZnO; this is benecial for the transfer of electrons from the noble metal nanoparticles to ZnO. 16,17,29 As for ZNR/AuPd, other than the photo-excited electrons and holes in the interior and at the surface of ZNR, the electrons in AuPd were also excited by visible light and then were transferred to the surface of ZNR (Fig. 7(a)).…”

“…In addition, the surface plasmon resonance (SPR) of noble metal nanoparticles contributes to electron excitation within the visible range. 16,17 For high recombination of electron-hole pairs and limited utilization of light related to the ZNR array electrodes, it is worth exploring the synergistic effect by combining the advantages of graphene coating and AuPd nanoparticle decoration on the surface of ZNR arrays.…”

“…from a broad assortment of food contact materials mainly resulting from polycarbonates as well as epoxy resins, such as infant feeding bottles, tableware, storage containers, and food can linings, [12][13][14] and thus, humans may regularly consume trace amounts of BPA. Extensive research studies have shown that BPA is an environmental endocrine disrupting chemical, which can mimic and interfere with hormonal activities by disrupting growth, development, reproduction and reduction in immune function of humans, 15,16 and also it can initiate probable cause for various types of cancer, 17 even at very low concentration. To protect the noxious effect and the potential health risk of BPA, the development of sensitive and specific method with reliable, rapid and real time analysis of trace level of BPA is highly significant and desired for safe of human life.…”

A versatile nano-molybdenum-iron-zinc-oxide (Fe2MoO4•Fe3O4•ZnO) nanoparticles (NPs) were prepared by co-precipitation method. The as-synthesized catalyst was characterized by several analytical techniques such as XRD, SEM, and FTIR spectroscopy. From the XRD pattern, particle size of the synthesized nanocomposite was calculated and found to be 20.5 nm. Elemental composition and their homogenies distribution in Fe2MoO4•Fe3O4•ZnO was confirmed by EDS study. The proposed Bis-phenol (BPA) chemical sensor with active Fe2MoO4•Fe3O4•ZnO NPs displays good selectivity with lower detection limit (DL) and longterm stability with enhanced electrochemical response. The calibration plot is linear (r 2 : 0.9978) over the concertation range (LDR) of 0.1 nM0.1 mM of BPA. The calculated sensitivity is 2.2468 µAµM-1 cm-2 with detection limit (DL) of 42.25±2.11pM at signal to noise ratio of 3(S/N). The BPA chemical sensor fabricated with Fe2MoO4•Fe3O4•ZnO NPs may be a promising with high sensitivity in reliable I-V method. Thus, this novel effort initiates a well-organized way to the development of reliable Fe2MoO4•Fe3O4•ZnO NPs/binder/GCE chemical sensor for efficiently detection of real hazardous toxins in environment as well as health career sector in a broad scale.
