An Antibacterial Nonenzymatic Glucose Sensor Composed of Carbon Nanotubes Decorated with Silver Nanoparticles

Abstract

A glucose sensor composed of silver nanoparticles decorated carbon nanotubes (Ag‐NPs/CNTs) prepared by ion implantation is described. Ag‐NPs with size of 2–4 nm are uniformly distributed in the CNTs after ion implantation. This process provides a strong combination between Ag‐NPs and CNTs and can effectively prevent the Ag‐NPs from aggregation. A linear range of 125 µM to 10 mM towards glucose determination was obtained. The Ag‐NPs/CNTs electrode shows minimal interferences from co‐existence species such as uric acid and ascorbic acid and an antibacterial rate of 94 % towards E. coli.

“…[ 1–5 ] To date, a number of applications have been achieved based on the embedded metallic NPs in a wide range of fields, including photonics, biology, chemistry, energy, and information science. [ 6–10 ] The tailoring of LSPR effect in nanocomposites is of vital importance to the emergence of novel mechanisms and the improvement of device performance. In theory, it is closely associated with the NP species, shapes, sizes, dielectric environment, etc.…”

Mucilage-capped silver nanoparticles for glucose electrochemical sensing and fuel cell applications

“…7 The glucose oxidation peak current is sensitive to the electrode surface area, thus increasing the electrode surface area through its modication with particular materials will optimize the glucose oxidation. 8 Metallic nanoparticles are known for their high surface area relative to their volume making them the appropriate choice for electrode modication.…”

Cucurbit[n]uril (n = 6, 7) Based Carbon-Gold Hybrids with Peroxidase-Like Activity

“…The long-term goal of our group is to construct carbon, metal and carbon-metal hybrid nanomaterials for emerging catalytic, sensing and biological applications [ 11 , 12 , 13 , 14 , 15 , 16 , 17 ]. In our previous work, we developed carbon nanomaterials decorated with metal nanoparticles by ion implantation and chemical deposition [ 18 , 19 , 20 ], in which the metal particles adhered poorly to the carbon material. Recently, we developed a sonicationand solvothermal method to prepare carbon nanomaterials [ 21 , 22 , 23 ] that can degrade hydrogen peroxide to produce hydroxyl radicals, and thus possess intrinsic peroxidase-like activity [ 22 ].…”
