Green Hydrothermal Preparation of Ag-CP Nanocomposites with Lily Bulbs for Non-Enzymatic Glucose Detection
Journal of Electronic Materials(2024)
Abstract
Green synthesis represents a superior strategy for mitigating the adverse effects of chemical synthesis on the environment. In particular, the utilization of bio-sourced materials for nanomaterial synthesis constitutes a more sustainable and environmentally sound alternative. In this study, silver–carbon particle (Ag-CP) nanocomposites were prepared by a green hydrothermal method using lily bulbs as raw materials and were employed for glucose detection. Through the use of various physical characterization techniques, it was demonstrated that the natural lily hydrothermal method yielded carbon particles that were modified with Ag nanoparticles. The electrochemical characteristics of the Ag-CP nanocomposites for glucose sensing were investigated using cyclic voltammetry and chronoamperometry. The results showed that the constructed glucose sensor was capable of detecting concentrations within the range of 1–11 mM (R2 = 0.998), with sensitivity of 203.56 μA mM−1 cm−2 and a detection limit of 76.6 μM (S/N = 3). The Ag-CP nanocomposite sensor also exhibited notable electrocatalytic activity and remarkable anti-interference capability. In light of the exceptional sensing performance, coupled with the straightforward and cost-effective preparation process, the development of nanocomposite materials employing naturally sourced biological materials represents an attractive avenue for the production of eco-friendly nanocomposites.
