A Comparison between Silver Nanosquare Arrays and Silver Thin-Films as a Blood Cancer Prognosis Monitoring Electrode Design Using Optical and Electrochemical Characterization

Abstract: The development of silver (Ag) thin films and the fabrication of Ag nanosquare arrays with the use of an anodic aluminum oxide (AAO) template and leaf extracts were successfully carried out using the DC sputtering and spin coating deposition methods. Ag thin films and Ag nanosquare arrays are developed to monitor cancer prognosis due to the correlation between serum albumin levels and prognostic factors, as well as the binding of serum albumin to the surface of these electrodes. Nanosquare structures were fabr… Show more

“…Theoretically, the standard deviation can be calculated using the Laviron equation as follows: log ks = α log (1 − α) − log (RT/nFυ) − α(1 − α) nFΔE p /2.3RT where α is the standard deviation of current density, n is the number of electrons transferred (n = 1), F is the Faraday constant (96,485 C mol −1 ), and ∆E p is the potential difference [ 16 , 17 , 20 ]. From the calculations of standard deviation, the limit of detection (LOD) with varying scan rates (between 0.12 V s −1 and 0.2 V s −1 ) and varying concentrations as shown in Figure 2 a,b can be calculated.…”

“…This method is relatively low-cost because it uses a chemical–physical process that is safe in its preparation stage. Furthermore, there are many non-nanomaterials that can be fabricated into nanostructures, for instance by using the DC sputtering deposition method [ 17 ]. In this study, we fabricated ZnO nanosquare arrays on a fluorine-doped tin oxide (FTO) substrate that was thinly coated with Au.…”

“…Conventional methods to monitor the condition of blood cancer patients include bone marrow aspiration to evaluate blood cells and diagnose conditions related to the bone marrow of patients [8]. Spectroscopic and electrochemical methods have been widely developed for the early detection of blood cancer; however, the exploration of these methods for the monitoring of blood cancer patients is still rare [9][10][11].…”
