Label-free fluorimetric detection of CEA using carbon dots derived from tomato juice

Mint leaf derived carbon dots for dual analyte detection of Fe(iii) and ascorbic acid

“…4 Hydrothermal treatment, the solvothermal method, microwave irradiation, laser ablation, ultrasonication, chemical oxidation, arc discharge, etc constitute different approaches adopted for the fabrication of CDs. 1,5 During the last few years researchers have been exploring readily available natural carbon sources like lemon juice, 6 tomato, 7 pomegranate, 8 waste biomass, 9 potato, 10 etc. for the fabrication of carbon dots.…”

Facile and large-scale synthesis of green-emitting carbon nanodots from aspartame and the applications for ferric ions sensing and cell imaging

“…Unlike organic dye and semiconductor quantum dots, CDs usually own unique excitation-dependent fluorescence (FL) and break through the limitation of toxic heavy metal element during their formaiton. Thus, CDs show encouraging performance in the in vitro and in vivo bioimaging [4,5], chemical sensors and biosensor [6][7][8], fluorescent ink [9], light emitting diodes [10], drug delivery [11], medical diagnosis [12], catalysis [13] and so on.…”

Review—Chemical and Biological Sensors for Viral Detection

“…113 A glassy carbon electrode (GCE) was modified with GQD and the aptamer was adsorbed to the surface of GQDs due to the interactions between hydroxyl and carboxyl groups at GQDs edges and amine groups of the aptamer. 114 EIS was used to detect HCV core antigen using ferricyanide/ferrocyanide as a re-dox probe. The aptasensor exhibited two linear concentration ranges 10-70 pg mL −1 and 70-400 pg mL −1 with a detection limit of 3.3 pg mL −1 .…”
