“…The limit of detection (LOD) is defined as 3 s/k, where s represents the standard deviation of the blank and k represents for the slope of the linear calibration equation. Here, the LOD of the UCNC@DSiMOR/BPEI probe was determined to be 1.507 µmol/L, which is comparable to or lower than some of the previously reported detection limits for Cu 2+ (Table S2) [46][47][48][49][50][51][52]. Practical applications often contain a variety of ions and molecules that can interfere with Cu 2+ detection.…”

In this research, upconversion nanocrystals incorporated with MOR zeolite composites were synthesized using the desilicated MOR zeolite as a host for the in situ growth of NaREF4 (RE = Y, Gd) Yb/Er nanocrystals. The structure and morphology of the composites were studied with XRD, XPS, and TEM measurements, and the spectral studies indicated that the subsequent thermal treatment can effectively improve the upconversion emission intensity of Er3+. By using the NaYF4:Yb/Er@DSi1.0MOR-HT composite that holds the strongest upconversion emission, a probe of UCNC@DSiMOR/BPEI was constructed with the modification of branched poly ethylenimine for the detection of Cu2+. It was indicated that the integrated emission intensity of Er3+ shows a linear dependence with the logarithm value of the Cu2+ concentration ranging from 0.1 to 10 μM. This study offered a feasible method for the construction of UCNC@zeolite composites with enhanced upconversion emission, which may have a potential application as fluorescent probes for the detection of various metal ions by adjusting the doping luminescent center.

“…Fluorescent probes have attracted much attention because of their high sensitivity, good selectivity, fast response time, simple operation, and good biological imaging performance. In recent years, many small molecular uorescent probes for detecting Cu ions have been developed [14][15][16][17][18][19][20][21] . However, most of them have shortcomings such as complex synthesis, low selectivity, and slow response time.…”

Large accumulations of copper (Cu) ions in the human body may cause damage, including organ and brain damage. In recent years, studies have proven that a large accumulation of Cu ions can lead to Parkinson's disease and Alzheimer's disease, therefore it is great important to develop novel strategies for detecting trace Cu in environmental and biological samples. In this work, we designed two new coumarin-based colorimetric and fluorescent probes HQ1 and HQ2. These two probes could selectively respond to Cu2+ with obvious color and fluorescence changes, and the presence of other metal ions had no effect on these changes. The two probes also exhibited high sensitivity for Cu2+, with a detection limit as low as 1.81×10-8 M/ 1.57×10-8 M. Notably, the two probes showed potential practical applications and were successfully used for detecting Cu2+ in a test strip, A549 cells and living zebrafish larvae.

[14][15][16][17][18][19][20][21] However, most of them have shortcomings such as complex synthesis, low selectivity, and slow response time. It is well known that the key element of probe design is the ability of an excellently chosen fluorophore to combine with the detection group for specific recognition.…”

Large accumulations of copper (Cu) ions in the human body may cause damage, including organ and brain damage. In recent years, studies have proven that a large accumulation of Cu ions can lead to Parkinson’s disease and Alzheimer’s disease; therefore, it is great important to develop novel strategies for detecting trace Cu in environmental and biological samples. In this work, we designed two new coumarin-based colorimetric and fluorescent probes, HQ1 and HQ2. These two probes could selectively respond to Cu2+ with obvious color and fluorescence changes, and the presence of other metal ions had no effect on these changes. The two probes also exhibited high sensitivity for Cu2+, with a detection limit as low as 1.81 × 10–8 M/1.57 × 10–8 M.
