Graphene oxide nanoribbon and polyhedral oligomeric silsesquioxane assembled composite frameworks for pre-concentrating and electrochemical sensing of 1-hydroxypyrene

Effect of octa(aminopropyl) polyhedral oligomeric silsesquioxane (OapPOSS) functionalized graphene oxide on the mechanical, thermal, and hydrophobic properties of waterborne polyurethane composites

“…Very recently, POSS has been used to modify some nanoparticles, especially the graphene materials . This novel nanomaterial that consists of graphene sheets decorated with silsesquioxane molecules has been used in different application areas based on specific principles . Based on this idea, some inferior properties of WPU might be improved by introducing this novel nanomaterial.…”

Controlled chemistry of tailored graphene nanoribbons for electrochemistry: a rational approach to optimizing molecule detection

“…The electrochemical 5 sensing of model electroactive molecules in the presence of reduced GNR-modified screen-printed electrodes has been shown to display a higher sensitivity compared to the sensitivity of a bare screen-printed electrode 17 . Various GNR-based sensors and biosensors [23][24][25] have been developed for the detection of urea 26 , 10 glucose 27 , 1-hydroxypyrene 28 , cysteine 29 , brevetoxin B 30 , and 2,4,6-trinitrotoluene 31,32 . These sensors displayed excellent electrochemical responses in terms of reproducibility, a low detection limit, and a high selectivity in all cases.…”

Pre-concentration and in situ electrochemical sensing of 1-hydroxypyrene on an electrodeposited poly(3-methylthiophene) film modified electrode

“…However, the selectivity of the P3MT modified electrode is better than that of the electrodes above, showing negligible interference of UA and common interfering cations and anions. Compared with the layer-by-layer assembled graphene oxide nanoribbon/polyhedral oligomeric silsesquioxane (GON/ OA-POSS) n composite film [47], the electropolymerization of poly(3-methylthiophene) on electrode needs only several minutes. Moreover, the obtained poly(3-methylthiophene) modified electrode exhibited good reproducibility, long-term stability and good electrocatalytic activity to the oxidation of 1-OHP.…”
