Nitrogen-doped carbon quantum dots for fluorescence sensing, anti-counterfeiting and logic gate operations

“…Abnormal levels of AA are associated with several diseases and health issues, such as cardiovascular diseases, 1 kidney stones, 2 iron-deficiency anemia, 3 stomach convulsion 4 and atherosclerosis. 5 Furthermore, due to its antioxidant properties, AA was widely used in the fields of food, beverages, pharmaceutical preparations, and cosmetics. 6 Thus, the importance of accurately measuring AA levels underscores the need for the development of convenient and effective quantitative methods.…”

Investigation of the photoactivation effect of TiO2 onto carbon-clay paste electrode by cyclic voltammetry analysis

“…However, they have shown some limitations which include high prices, complexity of their implementation and the manipulation difficulty in-situ analyses compared to electroanalytic methods. Therefore, electroanalytic techniques have exhibited promising application due to their ease of implementation, high precision, inexpensiveness and easily transportable apparatus for in-situ analyses [ [40] , [41] , [42] , [43] ].…”
