Aligned carbon nanotube modified carbon fibre coated with gold nanoparticles embedded in a polymer film: Voltammetric microprobe for enzymeless glucose sensing

Preparation of catalytic films of the Au nanoparticle–carbon composite tubular arrays

“…6 However, the catalyst NPs were attached onto the outer surface of the sidewalls of the nanotubes, 7 which often suffer from the NP leakage from the films, resulting in the low recyclability of the catalytic films. 6 However, the catalyst NPs were attached onto the outer surface of the sidewalls of the nanotubes, 7 which often suffer from the NP leakage from the films, resulting in the low recyclability of the catalytic films.…”

Role of Additives in the Combustion of Ammonium Dinitramide

“…In particular, carbon fibers (CFs) have received much attention in enzyme‐based biodevices for glucose monitoring 5f. 7 However, some research has focused on developing enzymeless devices for glucose monitoring 8. Some characteristics are considered important for CF‐based biodevice fabrication, such as flexibility and conductivity 9.…”

One pot synthesis of poly(5-hydroxyl-1,4-naphthoquinone) stabilized gold nanoparticles using the monomer as the reducing agent for nonenzymatic electrochemical detection of glucose

“…Poyraz et al prepared poly(o-toluidine) (POT) nanofiber/metal nanoparticle composite modified graphite working electrodes which gave rapid responses with a sensitivity of 37 mA cm À2 mM À1 and a limit of detection (LOD) of $0.027 mM in alkaline medium [7]. Sebez et al reported the use of polyethyleneimine modified gold nanoparticles on carbon fiber coated with aligned carbon nanotubes in nonenzymatic glucose oxidation at physiological pH of 7.4 [18]. Rong et al showed that electrodeposited Au nanoparticles coated with polymers with intrinsic microporosity are highly resistive to poisoning during glucose oxidation in pH 7 [20].…”

“…Au nanoparticles have received attention for this application due to the ease of synthesis using wet chemical methods with excellent size and shape control [17][18][19] in addition to their aforementioned high catalytic activity for glucose oxidation. Importantly, the polymer stabilized Au NPs are highly stable, and their high activity is retained due to their relatively weak interaction with the polymer.…”
