Flexible 3D nitrogen-doped carbon nanotubes nanostructure: A good matrix for enzyme immobilization and biosensing

Fundamentals and scopes of doped carbon nanotubes towards energy and biosensing applications

“…Glucose can be easily identified through amperometric monitor for the hydrogen peroxide released quantity. Zhang et al, have reported their study on the usage of flexible 3Dnitrogen-doped carbon nanotubes nanostructure as matrix for enzyme immobilization and biosensing[127]. In this work, an easy and scalable method for manufacturing a biosensor for detection of glucose was deevloped by glucose oxidase GOx immobilisation onto 3D N-doped CNTs support, based on electrospun carbon nanofibers film.…”

“…The biosensor has been found to exhibit very high reproducibility, good stability for enzime storage, anti-interferences high ability and high aplicability in real tests. Relatively simple preparation method as well as atractive analitical performances promotes this robust electrode for high performance electrochemical sensors development[127].…”

Three-dimensional N-doped carbon nanotube@carbon foam hybrid: an effective carrier of enzymes for glucose biosensors

“…7A). The as-prepared biosensor could reach the 95% , which was larger than that of GOD/ MWCNTs-chitosan (1.0-10.0 mM), 35 GOD-NCNT@CNFs (0.1-12.5 mM), 15 Naon-mesocellular graphene foam-GOD/GCE (1.0-12.0 mM) 36 , and ERGO-MWCNT/GOD/Nf electrode (0.01-6.5 mM). 37 Moreover, the detection of limit (LOD) was 5.0 mM (S/N ¼ 3), which was practicable for the determination of human blood sugar concentration (4.4-6.6 mM).…”

“…Those results were similar to the previous report. 15 The control experiments indicated that T c ¼ 800 C was the best temperature among the three studied temperature. Therefore, in the following studies, T c ¼ 800 C was selected for synthesizing 3D N-CNT@CF hybrid.…”

“…To address this issue, some self-supported conductive scaffolds, including graphene, 13 electrospun carbon nanobers mats, [14][15][16] carbon ber cloth/paper 17 are oen used as substrate to form three-dimensional (3D) N-CNTs hybrids for biosensing. The enhanced specic surface area and high electrochemical activity of those 3D conductive networks were as expected as a superior material in achieving DET of redox enzymes, which is deeply embedded redox factor of the enzyme.…”
