A novel carbon dot/Rhodamine B-based ratiometric fluorescent probe was developed for a highly sensitivity and selective detection of nitrite (NO ). The probe showed colour changes from blue to orange under ultraviolet light in response to NO with a detection limit as low as 67 nM in the range of 0 to 40 μM. A ratiometric fluorescent test paper was successfully prepared using the probe solution, which demonstrated its feasibility towards a rapid and semi-quantitative detection of NO in real samples.
开发了一种基于新型碳点/罗丹明B的比率荧光探针，用于高灵敏度和选择性地检测亚硝酸盐（NO₂⁻）。该探针对NO₂⁻响应时，在紫外光下颜色从蓝色变为橙色，在0至40 μM范围内检测限低至67 nM。使用该探针溶液成功制备了比率荧光试纸，证明了其对实际样品中NO₂⁻进行快速半定量检测的可行性。
