Abstract: Due to the advanced fluorescence property of N-carbon quantum dots (N-CQDs), a new method to detect pathogenic fungi by newly synthesized cornstalk N-CQDs modified with water-soluble amphotericin B (N-CQDs@AmpB) was developed. Specifically, N-CQDs with blue fluorescence were initially synthesized according to a previous report and modified with amphotericin B on their surfaces. Subsequently, the as-prepared N-CQDs@AmpB was used to detect Candida albicans, exhibiting a linear range of 2.60 × 105 to 1.99 × 108 c… Show more

“…Carbon quantum dots (CQDs) are a kind of nano-sized spherical carbon fluorescent material with unique advantages of light stability and sensitivity [ 30 , 38 , 39 ]. So far, different types of biomass materials, including lycium [ 40 ], hair [ 27 ], sugarcane bagasse pulp [ 41 ], Citrus limon peels [ 42 ], orange juice [ 28 ], tobacco [ 43 ], watermelon juice [ 30 ], corn juice [ 44 ], and carica papaya juice [ 45 ] have been used to synthesize CQD.…”

“…The fluorescence property of nitrogendoped CQD (NCQD) was utilized for the selective detection of Candida albicans, pathogenic fungi through the synthesis of NCQD modified with watersoluble amphotericin B (NCQD@AmpB). [174] Low detection time and minimum interference with other sam ples were the main advantages of this conjugate composite. Hydrothermal carbonization was employed to synthesize CQD from agricultural cornstalk and was doped with nitrogen using ethanediamine as a source of nitrogen.…”
