“…Also microsensors have been used in various applications involving the detection and measurement of the environmental and atmospheric hazardous chemicals as well as body glucose. Suneesh et al [396]reported an electrochemically anodized Ta 2 O 5 honeycomb nanostructure as the non-enzymatic glucose sensor. Morphological studies proved that the nanopores were highly uniform with an average diameter of 30±2 nm, and the pore size was reduced to 24 nm and 18 nm during subsequent electrodeposition of Pt and CuO inside the nanopores.…”

“…The non-enzymatic glucose sensor with high specific surface area has high sensitivity (response time ＜ 3 s), selectivity, specificity (free of interfering from ascorbic acid, uric acid, dopamine and acetaminophen), and wide range of detection (and a low detection limit of 1 μM; linear response to glucose up to 31 mM) (Fig. 39) [396]. Similarly, fourfold and threefold greater activity have been found in the fibers with mesoporous honeycomb structure than conventional nontemplated silica samples and horseradish peroxidase immobilized silica powders, in respective [397].…”

“…PPy-doped functionalized MWCNTs. The synthesis of high aspect ratio composite materials using ECPs through electrochemical polymerization for glucose biosensor application has been well studied 16 , 17 . The anodic polymerized PPy in the form of nanowires, nanoparticles and layered structures at a low applied voltage not only improves enzyme immobilization but also improves the sensing performance of enzymatic electrochemical-based glucose biosensors.…”

“…The anodic polymerized PPy in the form of nanowires, nanoparticles and layered structures at a low applied voltage not only improves enzyme immobilization but also improves the sensing performance of enzymatic electrochemical-based glucose biosensors. Moreover, the inherent electroactive polymeric activities and a tendency to integrate with hydrogel-forming porous composite matrix ensure that PPy retains its benefits in biomedicine, engineering, and highly-sensitive amperometric immunosensors 17 – 19 .…”

Herein, we report preparation of a bio-nanohybrid material of homogenously dispersed functionalized multiwall carbon nanotubes (fMWCNTs) in Nafion (Nf) doped with polypyrrole (PPy) and followed by one-step in situ electrochemical polymerization along with glucose oxidase (GOx) on a platinum (Pt) electrode. The bioengineered Nf-GOx-fMWCNTs-PPy/Pt electrode showed excellent electrocatalytic performance to detect glucose with a high sensitivity (54.2 μAmM−1 cm−2) in linear range of up to 4.1 mM as well as a low detection limit of 5 μM (S/N = 3), response time within 4 s, good selectivity, stability, and practical applicability. It is our hope that the comprehensive results will contribute to design an efficient glucose biosensor with practical prospects for biomedical applications.

Enzyme-free monitoring of glucose utilization in stimulated macrophages using carbon nanotube-decorated electrochemical sensor

Carbon nanotubes (CNTs) have been extensively explored for a diverse range of applications due to their unique electrical and mechanical properties. CNT-incorporated electrochemical sensors have exhibited enhanced sensitivity towards the analyte molecule due to the excellent electron transfer properties of CNTs. In addition, CNTs possess a large surface area-to-volume ratio that favours the adhesion of analyte molecules as well as enhances the electroactive area. Most of the electrochemical sensors have employed CNTs as a nano-interface to promote electron transfer and as an immobilization matrix for enzymes. The present work explores the potential of CNTs to serve as a catalytic interface for the enzymeless quantification of glucose. The figure of merits for the enzymeless sensor was comparable to the performance of several enzyme-based sensors reported in literature. The developed sensor was successfully employed to determine the glucose utilization of unstimulated and stimulated macrophages. The significant difference in the glucose utilization levels in activated macrophages and quiescent cells observed in the present investigation opens up the possibilities of new avenues for effective medical diagnosis of inflammatory disorders.
