“…These properties reflect the high number of similar devices which have been realized in recent years. Additional examples where the glassy carbon electrode is coated with hybrid nanostructured composites include: reduced MoS 2 -AuNPs for the double detection of zearalenone and fumonisin B1 mycotoxins in food [ 29 ]; (3-aminopropyl)triethoxysilane-modified graphene oxide (GO)-AgNPs for detection of chloramphenicol in food [ 30 ]; thiourea capped-ZnS quantum dots (QDs)-AuNPs for detection of β-casomorphin 7 in urine [ 31 ]; AgNPs-GQDs containing core-shell Cu-In-S/ZnSQDs for detection of ractopamine in urine and serum [ 32 ]; magnetic reduced GO-Fe 3 O 4 -Cu 2 O and Ag-resorcinol-formaldehyde NPs-Ag nanodots (NDs) for detection of prostate specific antigen in serum [ 33 ]; reduced GO-AgNPs and prussian blue-AuNPs for detection of acetamipridin in food [ 34 ]; reduced GO-AuNPs for detection of glycated albumin [ 35 ]; MXene-AuNPs for detection of chloramphenicol in food [ 36 ]; PtNPs-MIL-101(Fe) MOFs for detection of aflatoxin M1 in food [ 37 ]; and bimetallic CoNi-MOFs with graphene-like nanosheet structure to detect enrofloxacin in food, water and serum [ 38 ].…”

The demonstration of the first enzyme-based electrode to detect glucose, published in 1967 by S. J. Updike and G. P. Hicks, kicked off huge efforts in building sensors where biomolecules are exploited as native or modified to achieve new or improved sensing performances. In this growing area, bionanotechnology has become prominent in demonstrating how nanomaterials can be tailored into responsive nanostructures using biomolecules and integrated into sensors to detect different analytes, e.g., biomarkers, antibiotics, toxins and organic compounds as well as whole cells and microorganisms with very high sensitivity. Accounting for the natural affinity between biomolecules and almost every type of nanomaterials and taking advantage of well-known crosslinking strategies to stabilize the resulting hybrid nanostructures, biosensors with broad applications and with unprecedented low detection limits have been realized. This review depicts a comprehensive collection of the most recent biochemical and biophysical strategies for building hybrid devices based on bioconjugated nanomaterials and their applications in label-free detection for diagnostics, food and environmental analysis.

“…The aptamer is a single synthetic strand of RNA or DNA with exceptional properties presenting high specificity regarding the targets (Roushani and Shahdost-fard 2018;Shahdost-fard and Roushani 2016;Tan et al, 2013). In the last two decades, aptamer-based sensors (aptasensors) have been applied in various applications (Nutiu and Li 2005;Roushani et al, 2020;Roushani 2019, 2020;Yan et al, 2010). Taking advantage of the aptamers, the first fluorometric aptasensor for MAMP detection has been introduced by Saberi et al, in 2018.…”

“…Successful implementation relied on modified antibodies on AgPdNPs and covalent bonding proteins on the rGO/SPCE electrode. A sensor was developed using graphene quantum dots (GQDs), quantum dots (QDs), and a AgNP-modified GCE with a Rac-binding aptamer, forming an AgNPs/QD@GQD/GCE . It served as an impedimetric aptasensor for ultrasensitive Rac detection in human biological fluids.…”
