Soft, flexible and conductive interfaces, which can be used as electrode materials integrated with commercial electronic components and the human body for continuous monitoring of different analytes are in high demand in wearable electronics.
We report results of studies related to fabrication of nanostructured graphene oxide (GO) based electrochemical genosensor for neonatal sepsis detection. Initially, we have selected fimA gene of E. coli for...
Soft and conductive interfaces are valuable in wearable electronics as they are capable for integration
of diverse classes of electronic and sensor technologies directly with living body which can be used as
health monitoring systems. In present work, we explore the development of multi-walled carbon
nanotube-ethylene vinyl acetate nanocomposite (MWCNT-EVA) film and their properties. Oxidation
of MWCNT is known to improve their dispersion properties and increase the electrical conductivity
of MWCNT-polymer nanocomposites. Thus, pristine MWCNTs (p-MWCNTs) and functionalized
MWCNTs (f-MWCNTs) were further used as conductive filler to construct p-MWCNT-EVA and
f-MWCNT-EVA nanocomposite films. The films were characterized by Fourier-transform infrared
spectroscopy, scanning electron microscopy, energy dispersive X-ray analysis and electrochemical
technique. The results indicated that the chemical oxidation of p-MWCNT generates carboxylic function
at the p-MWCNT surface important for sensor fabrication. The concentration of carboxylic functional
group in f-MWCNT higher than in nanocomposites. The f-MWCNT-EVA nanocomposite film electrode
surface show much higher conductivitythan p-MWCNT-EVAnanocomposite film. Thus, the soft and
flexible f-MWCNT-EVA nanocomposite films are effective for the development of electrochemical
platform for biosensor fabrication in wearable applications.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
