Recent advances in the development of electrochemical hydrogen peroxide carbon nanotube–based (bio)sensors

Functionalized multi-walled carbon nanotube/silver nanoparticle (f-MWCNT/AgNP) nanocomposites as non-enzymatic electrochemical biosensors for dopamine detection

“…Compared with SWCNTs, MWCNTs production generates higher yield and lower cost per unit, as well as higher thermochemical stability, maintaining its properties when functionalized [17]. MWCNT based sensors have been developed for biological molecule detection, such as non-enzymatic H 2 O 2 [18][19][20], ascorbic acid [21,22], or glucose [23,24]. To enhance the sensor performance, such as longterm stability and selectivity, composites of two or more materials have been explored for electrode modification to study its potential synergistic effects.…”

MWCNT‐Organoimido Polyoxomolybdate Hybrid Material: Analytical Applications for Amperometric Sensing of Hydrogen Peroxide

“…In the last years, hydrogen peroxide became a very important biomarker due to the connection with different pathologies like Parkinson disease, cancer and cardiovascular diseases [5, 6]. Therefore, the development of sensitive, selective, friendly and low‐cost sensors, with possibility of miniaturization for decentralized measurements, is highly required [7]. Electrochemical sensors have demonstrated to be very useful for the quantification of different analytes [8, 9].…”

“…Their further rediscoveries, including the high impact report on the synthesis of hollow carbon molecules & their crystal structures by arc discharge evaporation method for the first time by Japanese researcher Sumio Iijima published in 1991 [2], the field of CNTs continues to be one of the hottest topics in nanoscience and nanotechnology which has been already around 30 years. Nano carbons are the carbon allotropes with nanometer-scale composed mainly of (0D-3D) dimensional forms; fullerenes(0D), found by Kroto and Smelly in 1985 [3], carbon nanotubes, (1D), graphene (2D), found by Novoselov and Geim in 2004 [4] and nano diamond (3D), found by Soviet scientists in July 1963. CNTs are a hexagonal array of carbon atoms rolled up into a long thin, hollow cylinder and are known for their size, shape, and remarkable properties.…”

“…Researcher's great interests have been attracted by CNTs by its tiny size structure and exhibiting many interesting and often unexpected and extraordinary mechanical [5][6][7] electric [8] , thermal stability [9] and optical [4] properties because of which a great application in electro chemical, biosensors and chemical sensors [10], composites [11], field emission devices [12], gas or energy storage, probe tips, etc. It is predicted that introducing CNTs into cement-based materials via nanotechnology will open up a whole wide range of multifunctional cement-based materials.…”

“…SDS is one of the most commonly used water soluble amphiphilic dispersants, which helps to de-bundle CNT by electrostatic and steric repulsion [18]. PVP is polymeric surfactants [19], has a good stable to environment, easy processing and moderate electric conductivity [4]. Which tends to wrap around the CNTs center through their flexible or semi-flexible sections with dispersion mechanism of stacking/Amine e-pair donation.…”
