The surface plasmon resonance (SPR) is a phenomenon based on the combination of quantum mechanics and electromagnetism, which leads to the creation of charge oscillations on a metal-dielectric interface. The SPR phenomenon creates a signal which measures refractive index change at the metal-dielectric interface. SPR-based sensors are being developed for real-time and label-free detection of water pollutants, toxins, disease biomarkers, etc., which are highly sensitive and selective. Smartphones provide hardware and software capability which can be incorporated into SPR sensors, enabling the possibility of economical and accurate on-site portable sensing. The camera, screen, and LED flashlight of the smartphone can be employed as components of the sensor. The current article explores the recent advances in smartphone-based SPR sensors by studying their principle, components, application, and signal processing. Furthermore, the general theoretical and practical aspects of SPR sensors are discussed.

“…The limit of detection (LOD) is the lowest concentration that can be measured or detected, and it was found to be 1 × 10 2 CFU/mL [72] [73]. A study by Yaghubi and co-workers reported similar results using Au-NPs conjugated with antibodies [74]. Our results were much lower or better compared to the reported literature, for example, Haicao and co-workers reported LOD of 2 × 10 8 CFU/mL using mercaptoethylamine modified Au-NPs for E. coli O157:H7 [75].…”

Herein, we demonstrate a simple and inexpensive one-pot green synthesis of silver nanoparticles (Ag-NPs) functionalised with a combination of banana peel (Musa paradisiaca) and grape (Vitis vinifera) fruit extracts. The reaction mixture of aqueous silver nitrate, banana peel and grapefruit extracts revealed a dark brown colour after a reaction time of 18 minutes, which indicates the presence and the successful synthesis of silver nanoparticles. The optical and structural properties of the green synthesised nanoparticles were analysed using UV-Visible spectroscopy (UV-Vis) which confirmed an absorption band at 440 nm. The polydispersity nature and the AgNPs sizes of 30 nm were revealed using small angle X-ray scattering (SAXS) and high-resolution transmission electron microscopy (HR-TEM) techniques. Fourier transform infrared spectroscopy (FT-IR) studies revealed the structure of these nanoparticles which included carbonyl groups, primary amine groups, OH groups and other stabilizing functional groups characteristic of the properties of combined extracts. A simple, quick, less time-consuming surface plasmon resonance (SPR) and electrochemical method in the form of optical and electrochemical sensors have been developed for the detection of Escherichia coli 0157:H7. The obtained limit of detection (LOD) values for SPR and GBPE-Ag-NPs/GCE-based sensor systems were found to be 1 × 102 CFU/mL and 3.5 × 101 CFU/mL, respectively. The obtained values fall within the range

“…It showed high speci city, speed, limit of detection of about 10 CFU/mL and precision with no requirement of specialized hands thereby serving as a great tool for detection of other clinical specimens. A different strategy i.e., rapid immunochromatographic assay using Fe 3 O 4 /Au composite nanoparticles were synthesised for the detection of same pathogen (E. coli O157:H7) 24 . This study by Xue et al, made anti-E. coli O157:H7 IgY and conjugated that to a core/shell structured super-paramagnetic composite nanoparticle.…”

Antibody research field has dramatically revolutionized the pharmaceutical industry for diagnosis and therapeutic applications. Ever since after the approval of first monoclonal antibody by US-FDA, researchers have been extensively working on this new class of drugs called antibodies. Owing to its inexpensive, fast production of no ethical concern, IgY from avian source i.e., chicken-IgY has attracted many researchers. Nevertheless, the combination of deploying nanoparticle and IgY-technology has a great potential in making tremendous impact in combating the issues of biosensing and antibody delivery. The so-called nano-immunotherapy, that uses nanoparticles as a carrier to safely and effectively transport IgY antibodies to the target region, may be the most cutting-edge, sophisticated, effective, and best method to address antibody delivery-related problems. Utilizing the proper moieties, functionalized nanomaterials can help improve the localization of antibodies at a specific site, thereby reducing off-targeting problems, protect them from enzyme-mediated degradation, lessen side effects, and decrease the frequency of dosage by high loadings in a single dose. Overall, this review presents the so-far postulated frameworks on the usage of nanomaterials with IgY for diagnostic and therapeutic applications thereby discussing the immediate need in shifting the paradigm of employing nano-IgY technology to set a benchmark in healthcare industry.
