Novel fluorescent nitrogen and phosphorus-doped carbon dots (Aa N,P-CDs) derived from Auricularia auricula were successfully prepared via a simple hydrothermal method. The Aa N,P-CDs showed high selectivity and sensitivity in detection of 4-nitrophenol (4-NP) and Ag(I) and good linear ranges of 4-NP (0–37.5 μM, R² = 0.9967) and Ag(I) (0–25 μM, R² = 0.9934). The low detection limits were 198 nM and 74.35 nM, respectively. This showed that static quenching dominated in Ag(I) quenching of the Aa N,P-CD fluorescence, while that of 4-NP was the inner filter effect. The Aa N,P-CDs were successfully used to detect 4-NP and Ag(I) in real water and soil samples. Cell imaging indicated that Aa N,P-CDs showed low biotoxicity and good biocompatibility, which provided a new insight into bioimaging application and environmental pollutant detection.

水合木耳氮，磷掺杂碳点的水热合成及其在Ag（I）和4-硝基苯酚检测及生物成像中的应用

通过一种简单的水热法成功地制备了来自木耳的新型荧光氮和磷掺杂碳点（Aa N，P-CDs）。的了Aa N，P-CD的显示，检测-4-硝基苯酚（4-NP）和Ag（高选择性和灵敏度我）和良好的线性4-NP的范围（0-37.5μM，- [R ² = 0.9967）和Ag（I）（0–25μM ，R ² = 0.9934）。低检测限分别为198 nM和74.35 nM。这表明静态猝灭在Aa的Ag（I）猝灭中占主导地位N，P-CD荧光，而4-NP则是内部滤光效果。的了Aa N，P-光盘被成功用来检测4-NP和Ag（我）实水和土壤样品英寸细胞成像表明，AA N，P-CDs具有较低的生物毒性和良好的生物相容性，为生物成像的应用和环境污染物的检测提供了新的认识。
