Double-signal quantification of amoxicillin based on interaction with 4-aminoantipyrine at copper and nitrogen co-doped carbon quantum dots as an artificial nanozyme

Facile fabrication of boron and nitrogen co-doped carbon dots for “ON–OFF–ON” fluorescence sensing of Al3+ and F− ions in water samples

“…[17][18][19][20] The photoluminescence properties of CDs are the most interesting features that broaden their applications in quantitative determination. 21 Wei et al prepared CDs for the estimation of Al 3+ ion in water samples; it involves mixing of CDs with Al 3+ , allowing reacting for 10 min, uorescence was then measured at l exc. of 360 nm aer excitation of the mixture for 15 min.…”

A selective dual quenching sensor (EY/BG@CDs) for simultaneous monitoring of gentamicin and ketorolac levels in plasma: a highly efficient platform that caters to the needs of therapeutic drug monitoring

“…54 To calculate the fluorescence quenching efficiency ( F 0 / F ) of BG@CDs in the presence of KET, the Stern–Volmer equation was used: F 0 / F = K sv [Q] + 1. 63,64 Here, F 0 and F represent the fluorescence of BG@CDs in the absence and presence of KET, respectively. K sv denotes the Stern–Volmer quenching constant, and [Q] express the concentration of KET solution.…”

Double protein directed synthesis of chemically etched sulfur doped quantum dots for signal “on–off–on” sensing of glutathione mediated by copper ions

“…10 Among them, uorescence-based analytical approaches have received the most interest because of their wide dynamic linearity, low detection limit, and simplicity. [11][12][13] Therefore, a selective and sensitive uorescent nanoswitch was constructed for estimation of GSH in real samples.…”
