“…A similar observation also reported that the binding capacity of a cryogel towards template human serum albumin (HSA) present in non‐diluted serum is 390.2 mg/g whereas the binding capacity in binding studies is 25.9 mg/g , and also in our previous work reported, MIP towards HSA showed maximum adsorption capacity in urine (129.5 mg/g) whereas the binding capacity in binding studies is 86.7 mg/g . The UA , creatinine , and HSA in the human urine are found to be as ∼0.63–13.6 mM, ∼2.12–17.1 mM, and ∼0.2–0.39 µM, respectively. However, the adsorption capacity of human serum albumin (IF, 1.05) as well as creatinine (IF, 1.21) and uric acid (IF, 1.15), which are final metabolites in urine, is not very significant compared to ATP adsorption efficiency, suggesting that the interference of other metabolites to these ATP binding sites is nonspecific.…”

“…The adsorption capacity of MIP towards other than adenine base analogues UD, UA, Cre which are also final metabolites in urine, is very low compared to adenine base as well as ADP and AMP both which have the similar structure confirmation, as shown in Supporting Information Figure S11. In general, ADP and AMP concentration in urine is significantly less in comparison to UD, UA, and Cre [53,54]. Even though the adsorption capacity of ADP and AMP was higher than the UD, UA, and Cre, it was attributed to the size and shapes of the imprinting sites are matched with the ADP and AMP which are structurally similar to the template ATP, showing the highest adsorption capacity.…”

“…In this test, alkaline picrate reacts with creatinine to form an orange-red product that is measured spectrophotometrically. Other current methods include HPLC-MS/MS [2], HPLC-DAD [3,4], spectrophotometry [5], spectrophotometry using a portable microfluidic system [6], and electrophoresis with electrochemical [7], UV [8], and colorimetric detection [9].…”

“…Analytical procedures for the measurement of uric acid include HPLC-DAD [3,4], electrophoresis with UV detection [8], spectrophotometry with chemometric tools [12], electrochemical methods [13], colorimetric detection with multiple indicators [14], enzymatic reaction [15], and gold nanoparticles [16]. Only methods that involve separation techniques, such as chromatography [3,4] and electrophoresis [8], are able to determine both analytes simultaneously. However, these techniques involve the use of large volumes of toxic organic solvents, produce substantial amounts of waste that may be dangerous to the operator and the environment [17], and require laborious clean-up steps.…”

“…Other method is high performance liquid chromatography with UV absorbance detection [8]. However, the use of the electrochemical methods provides some advantages, such as short analysis time, simple experimental procedures, relatively economical instrumental requirements and high selectivity and sensitivity [2].…”
