Emerging graphene-based sensors for the detection of food adulterants and toxicants – A review

Nano-Enable Materials Promoting Sustainability and Resilience in Modern Agriculture

“…Various nanoscale materials/sensors, including metal-organic frameworks (MOFs), graphene oxide (GO), CNTs, molecularly imprinted polymers (MIP), nanozymes, and nanosensors, have been cooperatively used to detect, remediate, and extract unwanted compounds from food sources [ 120 ]. These nanoscale materials have also been used as components in devices tailored to the detection of chemical and biological contaminants, allowing the removal from the supply chain of toxic compounds, hence minimizing the distribution of contaminated products to the consumer [ 121 ].…”

Introduction of a multilayered fluorescent nanofilm into lateral flow immunoassay for ultrasensitive detection of Salmonella typhimurium in food samples

“…Very recently, two-dimensional nanomaterials, such as graphene oxide (GO), titanium carbide, black phosphorus, and molybdenum disulde, have been used as excellent carriers for the construction of ultrasensitive biosensors due to their massive surface areas, exibility, superior stability, and abundant surface groups. [31][32][33] Our previous works also demonstrated the combination of monolayer GO and other nanoparticles (e.g., QDs, AuNPs, and AgNPs) as high-performance lm-like nanotags for LFIA methods. [34][35][36] For example, the GO nanosheet loaded one layer of dense QDs can act as exible uorescent tags for simultaneous detection of two kinds respiratory pathogens in real respiratory tract samples via LFIA strip.…”

Electrochemical determination of synephrine by using nafion/UiO-66/graphene-modified screen-printed carbon electrode

“…As a typical two-dimensional nanomaterial, graphene (GN) has displayed many properties, including large specific surface areas, high chemical stability, and excellent electrochemical properties ( Raghavan et al, 2021 ). It is widely used to modify electrodes to achieve better results.…”
