“…Due to their unique characteristics, nanomaterials already have been used in several applications including medicinal, industrial and agricultural sectors (Servin and White 2016;Zhang et al 2016;Zuverza-Mena et al 2017). Concerning the agricultural application of nanomaterials, there is an increasing and unlimited uses in agriculture and food systems including nanofertilizers (Tarafdar et al 2014;Chhipa and Joshi 2016;Dubey and Mailapalli 2016), nanopesticides (Chhipa and Joshi 2016;Dubey and Mailapalli 2016), soil nano-reclaimants (Patra et al 2016;Floris et al 2017), nanosensors for nano-farming (Honeychurch 2014;Chhipa and Joshi 2016;Dubey and Mailapalli 2016;Yılmaz et al 2017), soil and water nanoremediators, etc. (Ingle et al 2014;Gomes et al 2016;Gil-Díaz et al 2016a, b;Gil-Díaz et al 2017).…”

“…SPR-based sensors have been successfully applied in the detection of some volatile compounds and gases like benzene, ammonia, chloroform, ethanol, methanol, ethyl benzene, 2-propanol, toluene, and acetone vapours [8,[26][27][28][29][30][31][32]. The performance of the sensors has been improved through various design modifications which include the incorporation of nanoparticles of different morphologies [33][34][35], bimetallic layers [2,[36][37][38][39], porous gold [40][41][42][43], graphene layer on gold [5,44], conducting and insulating polymer coatings [26,45,46], and metal oxide coatings [47,48]. However, SPR detection of acetone vapour has not been optimized for suitable applicability in diabetes monitoring and screening [32].…”

PANI/chitosan composite and a ternary composite comprising of PANI, chitosan, and reduced graphene oxide have been successfully synthesised and characterised using FTIR and UV-VIS spectroscopy. Optical constants of the composites were extracted from the UV-VIS spectra. The extracted parameters were applied in the simulation of a surface plasmon resonance (SPR) biosensor functionalised with PANI/chitosan and ternary composites. The aim was to explore the applicability of the composite-based SPR sensor in the detection of low-concentration acetone vapour within the range of 1.8 ppm–5.0 ppm for diabetes monitoring and screening. The functionalization of the SPR sensor with the PANI/chitosan and the ternary composites shows promising application of the sensor in the detection of acetone vapour at a low concentration down to less than 0.5 ppm. The maximum sensitivity values of about 60 and 180 degree/refractive index change were observed for PANI/chitosan and ternary composite sensing layers, respectively, in comparison with the bare gold-based SPR which shows no response up to 10 ppm concentration of acetone vapour in air. In addition, the two sensing layers show good selectivity to acetone vapour compared to ethanol, methanol, and ammonia. The response in the case of ternary composite shows better linearity with a correlation coefficient of 1.0 compared to PANI/chitosan- and gold-based SPR layers with 0.9999 and 0.9997, respectively.

“…In recent years, they have gained great attention in the fields of health science, drug discovery, diagnosis of infections, environmental and agricultural monitoring [26,29,30,31]. It has been proven that these sensors are also suitable for detecting target molecules/cells in complex media (e.g., blood, urine, stool, food, fruit juice) [32].…”

Identification of pathogenic microorganisms by traditional methods is slow and cumbersome. Therefore, the focus today is on developing new and quicker analytical methods. In this study, a Surface Plasmon Resonance (SPR) sensor with a microcontact imprinted sensor chip was developed for detecting Salmonella paratyphi. For this purpose, the stamps of the target microorganism were prepared and then, microcontact S. paratyphi-imprinted SPR chips were prepared with the functional monomer N-methacryloyl-L-histidine methyl ester (MAH). Characterization studies of the SPR chips were carried out with ellipsometry and scanning electron microscopy (SEM). The real-time Salmonella paratyphi detection was performed within the range of 2.5 × 106–15 × 106 CFU/mL. Selectivity of the prepared sensors was examined by using competing bacterial strains such as Escherichia coli, Staphylococcus aureus and Bacillus subtilis. The imprinting efficiency of the prepared sensor system was determined by evaluating the responses of the SPR chips prepared with both molecularly imprinted polymers (MIPs) and non-imprinted polymers (NIPs). Real sample experiments were performed with apple juice. The recognition of Salmonella paratyphi was achieved using these SPR sensor with a detection limit of 1.4 × 106 CFU/mL. In conclusion, SPR sensor has the potential to serve as an excellent candidate for monitoring Salmonella paratyphi in food supplies or contaminated water and clearly makes it possible to develop rapid and appropriate control strategies.
