“…When GFR is less than 15 mL/min per 1.73 m 2 , it is a sign and symptom of uremia, which requires dialysis or kidney transplantation . A variety of methods, therefore, have been developed for quantitative detection of creatinine, such as capillary electrophoresis, gas chromatography, liquid chromatography, mass spectrometry, and so on besides the mostly used strategy of Jaffe’s method and enzymatic digestion in clinical trials. − Actually, the colorimetric method, such as Jaffe’s method, is one of simplest, most convenient, and promising methods with not only fast naked eye-distinguishable results but quantitative determination by UV–vis spectrometer. However, picric acid forms an orange complex not only with creatinine but also with many other biomolecules (e.g., metabolins and drugs) in alkaline media.…”

A gold nanoparticle-based colorimetric sensor for the determination of creatinine was developed as an important index for early diagnosis of kidney function and corresponding renal diseases. Because of the unique synergistic coordination capability of adenosine and creatinine with Ag+ on a particle surface, our system exhibits an excellent selectivity to creatinine among various ions and biomolecules. There are good linear relationships of absorption changes (A 630 nm/520 nm) over creatinine concentrations, so both colorimetric qualitative detection by the naked eye and quantitative determination by UV–vis spectrometer could be realized with an excellent limit of detection compared with that of other methods. Finally, by testing creatinine in practical samples, such as urine mimic and bovine serum, good recoveries were obtained with proper relative standard deviations.

“…A glass bath and a heater/stirrer were used to adjust the rotation speed and the extraction temperature. A home‐made thermoelectric cooler was employed to cool the fibers during extraction. The solutions were under the corresponding extraction conditions for 2 min to reach equilibrium, before starting each extraction procedure.…”

A new metal‐organic coordination polymer, [Zn(μ‐mptrz)(mptrz)(μ‐en)0.5]n (mptrz− is 4‐methyl‐1,2,4‐triazole‐3‐thiolato), has been used to prepare a solid‐phase microextraction fiber using the direct immersion method. The fiber was well characterized, and showed superior properties. Scanning electron microscopy of the fiber shows a very porous and homogenous coating. The thermal stability, adhersivity and chemical stability were excellent for extracting analytes from harsh media and desorbing them in a high thermal inlet of a gas chromatograph. An anti‐cancer drug, tamoxifen, was extracted with this fiber and then analyzed by using gas chromatography with flame ionization detection. The main factors affecting the extraction of tamoxifen were optimized. The detection limit and linear range were 0.62 and 4–800 μg L−1, respectively. The intra‐day and inter‐day relative standard deviations were obtained at different concentrations, using a single fiber, and found to be 14.1–15.4 and 13.3%, respectively. The results were then compared with other works. Tamoxifen in two urine samples was successfully analyzed with the proposed method.
