“…The sensitivity, limit of detection (LOD) based on 3 S b /m, and limit of quantification (LOQ) based on 10 S b /m (S b is the standard deviation of the blank signals for n = 3, and m is the slope of the calibration plot) are estimated as 2.033 µA µM −1 cm −2 , 0.016 µM, and 0.053 mM, respectively. The proposed Ni-Co-P NSs/Nafion/GCE showed good comparability with some previous reports concerning electrochemical non-enzymatic DA sensors based on different transition-metal (including metal Ni, Co, or Ni/Co) compound materials ( Table 1 ) [ 39 , 43 , 44 , 45 , 46 , 47 ].…”

Figure 8a shows the DPV response at Ni-Co-P NSs/Nafion/GCE with increasing DA concentrations from 0 to 50 It is evident that the DPV response increased with the increase in DA concentration, and the inset of Figure 8a shows an amplified view of the DPV responses in the low-concentration region.…”

“…According to the slope ( S ) of the regression equations and standard deviation (Sb) of the mean values of 10 DPVs of the blank solution, LODs were calculated to be 6.32, 0.45, and 0.81 μM for AA, DA, and UA, respectively, by using the 3Sb/S equation [ 55 ]. Compared with other electrodes modified with various TMD- and CNF-based materials, the Co/MoSe 2 /PPy@CNF-modified GCE exhibits good and comparable analytical performance for the simultaneous determination of AA, DA, and UA (Table 1 ).…”

“…In terms of non-enzymatic-based assays, fluorescence spectrometry, liquid chromatography, and electroanalytical techniques are the most common non-enzymatic methods. 7,8 Among these, electrochemical recognition is considered a highly promising method due to its rapid response, high selectivity, low detection limit, and cost-effectiveness. The electrochemical method is considered a promising approach for UA detection.…”
