“…There are many reports in literature on various approaches to improve the analytical performance of bismuth and antimony modified electrodes for the detection of Pb 2 + and Cd 2 + detection in stripping voltammetry measurements [13,[37][38][39][40][41][42][43][44][45][46][47][48]. The detection limits obtained using Sb/Bi-GCE compare favorably with previously reported modified electrodes listed in Table 2.…”

This work reports on the electroanalytical performance of a glassy carbon electrode (GCE) modified with antimony and bismuth (Sb/Bi‐GCE) in detecting heavy metal ions using lead and cadmium as model analytes. The electroanalytical performance of the Sb/Bi‐GCE surface was compared to the bismuth modified glassy carbon electrode (Bi‐GCE) as well as the antimony modified glassy carbon electrode (Sb‐GCE). The Sb/Bi‐GCE exhibited excellent figures of merit compared to Bi‐GCE and Sb‐GCE surfaces. For example, the limit of detection for lead was 0.01 ppb using Sb/Bi‐GCE and 0.1 and 1 ppb on Bi‐GCE and Sb‐GCE, respectively.

“…Furthermore, the use of Nafion, a hydrophobic Teflon-like backbone with hydrophilic perfluoroether side chains bearing terminal sulfonic acid groups, has been a longstanding goal in the community for the development of various electrochemical sensors. Nafion exhibits not only excellent chemical inertness, catalytic activity, and high permeability to the cation but also an anti-fouling capability [132][133][134].…”

This dissertation concentrated on the development of nanomaterials-based miniaturized platforms for the detection of some important compounds/indicators from environmental, pharmaceutical, and clinical application. This dissertation can be classified into two main parts: (1) development of nanomaterials-based miniaturized platforms for optical sensing application, and (2) development of nanomaterials-based miniaturized platforms for electrochemical sensing applications. In the first part, two sub-sections were discussed. For the first sub-section, the paper-based colorimetric sensor for chloride ion determination using silver nanoprisms was developed. Using a smartphone as an optical readout, the color change from the oxidative etching of the silver nanoprisms to the silver nanospheres induced by chloride ion can be monitored. In the second sub-section, a screen-printed electroluminescent displaymodified with graphene oxidewas engineered for optical sensing applications for the first time. The potential of the proposed device was extended for a variety of applications, including a basic lamp, an ionic concentration sensor, a humidity sensor, and a human breath sensor. In the second part, electrochemical sensors were also developed. In this part, two sub-sections were discussed in detail. For the first sub-section, an anti-fouling electrochemical sensor for vitamin D determinationusing graphene/Nafion nanocompositewas developed. A greatly enhance in analytical performance and the anti-fouling capability was obtained. Lastly, in the second sub-section, a paper-based sequential microfluidic device modified with graphene and gold nanoparticles was developed for the fluid delivery system. Various target compounds including ascorbic acid, serotonin, and alpha-fetoprotein were chosen as model analytes and tested by the developed platform. Results obtained from these miniaturized devices demonstrated here provided a good promising for on-field testing with excellent sensitivity, selectivity, and portability.
