“…The CeO 2 NPs-GO was synthesized via a facile sonochemical method according to the literature technique. 30 The CeO 2 NPs-GO nanocomposite was prepared as follow; 1 mmol of Ce(NO 3 ) 3 .6H 2 O was dissolved in 30 mL deionized water and then 32% NH 4 OH aqueous solution was added drop-wise with simultaneous ultra-sonication for 60 min. After performing synthesis method mentioned above, GO suspension was added regularly to the mixture at 90°C.…”

In this study, a newly developed strategy is presented for phytase enzyme immobilization on a chemically modified cerium oxide nanoparticles decorated graphene oxide (CeO 2 NPs-GO) based on the surface of glassy carbon electrode (GCE). Fast Fourier transform square wave voltammetry (FFT-SWV) and cyclic voltammetry (CV) were used as detection techniques for phytic acid (PA) biosensor in [Fe(CN) 6 ] 3−/4− solution. The decrease in current of [Fe(CN) 6 ] 3−/4− solution toward increase in PA concentration on the CeO 2 NPs-GO electrode surface was elucidated in the range of 0.066 to 6.6 ppb with RSD of 3.8%. The newly developed PA biosensor provided a much lower detection limit (LOD = 0.001 ppb) than other reported electrochemical techniques for PA detection. Significant results were achieved using newly developed assay for detection of PA in spiked corn flour sample, which might be helpful in foods, feeds, livestock, agriculture and environmental sectors. No major organic compound, inorganic anions and cations were observed in the PA detection by using the proposed newly developed assay.

“…Ilkhani et al developed an electrochemical aptamer/antibody based immunosensor using AuNPs as the signaling probe for detecting EGFR with detection limit of 50 pg/mL (Ilkhani et al, 2015). A printable voltammetric genosensor based on a nanocomposite of nano-polyaniline and graphene oxide (GO)-ceria nanoparticles was developed for detecting mutation in a particular sequence of the adenomatous polyposis coli gene (Eskandari and Faridbod, 2018). The analysis is usually rapid, low cost, and highly sensitive.…”

In recent years, nanomaterials of different shape, size, and composition have been prepared and characterized, such as gold and silver nanoparticles, quantum dots, mesoporous silica nanoparticles, carbon nanomaterials, and hybrid nanocomposites. Because of their unique physical and chemical properties, these nanomaterials are increasingly used in point-of-care testing (POCT) to improve analytical performance and simplify detection process. They are used either as carriers for immobilizing biorecognition elements, or as labels for signal generation, transduction and amplification. In this commentary, we highlight recent POCT technologies that employ nanotechnology for the analysis of disease biomarkers, including small-molecule metabolites, enzymes, proteins, nucleic acids, cancer cells, and pathogens. Recent advances in lateral flow tests, printable electrochemical biosensors, and microfluidics-based devices are summarized. Existing challenges and future directions are also discussed.
