Fabrication of an imprinted polymer based graphene oxide composite for label-free electrochemical sensing of Sus DNA

“…2a and b show the 2 D bands at 2622 cm À1 and 2579 cm À1 , respectively, which confirmed the single layer of graphene oxide and modified graphene oxide. 49 In Fig. 2c and d the D and G bands observed at 1336 cm À1 and 1565 cm À1 , respectively, confirmed the backbone of graphene oxide.…”

Interacting effects of graphene oxide derivatives and trace metals on freshwater brown trout (Salmo trutta L.) behaviour at different stages of development

“…The next wave of GO applications in water purification might be related to the development of GO-based membranes with high inherent mechanical strength, outstanding antibacterial activity, and flawless antifouling properties. 67…”

“…The next wave of GO applications in water purification might be related to the development of GO-based membranes with high inherent mechanical strength, outstanding antibacterial activity, and flawless antifouling properties. 67 In general, this study provides interdisciplinary (nanomaterial engineering and biological) insights into the potential application of GO and its bioactivity in modifying the availability and toxicity of metals at low or close levels of environmental contamination. There was clear evidence that GO, alone or in combination with metal mixtures, had an adverse effect on the behaviour of brown trout larvae and juveniles.…”

ZnO-Nanorod/Ag2O-Nanoparticle/rGO-Nanosheet Heterostructures as Photocatalysts for Enhanced Degradation of Harmful Aqueous Phase Contaminants under Extended Visible Light Exposure

“…A single-layer two-dimensional (2D) carbon nanosheet structure called graphene that contains sp 2 hybridized carbon atoms with honeycomb lattice arrangements exhibits some outstanding electrical characteristics, including high transparency, large specific surface area, and ultrafast electron mobility . The highly conjugated network, high porosity and specific surface area, high conductivity, rich surface chemistry composition, and excellent UV light transmittance make graphene oxide (GO) and reduced graphene oxide (rGO)-related compounds ideal substrate for the construction of semiconductor-based photocatalysts for oxidative degradation of organic pollutants in wastewater treatment. − Improved visible light response and effective electron–hole pair separation were made possible by the impurity levels afforded by rGO, which finally boosted the photodegradation efficiency for the contaminants for the widely used ZnO/rGO photocatalyst. − …”
