Facile fabrication of a portable PANI-NFs/c-MWCNT nano-composite electrochemical sensor for gefitinib: application to human plasma

“…CNTs got significant attention in modification of the electrode surface due to their high conductivity, high mechanical strength, and high specific area. 23 Single-walled carbon nanotubes (SWCNTs) and multi-walled carbon nanotubes (MWCNTs) are the main types of CNT. 18 MWCNTs manifest important properties over SWCNTs such as huge surface area, high conductivity, ease of chemical modifiability, and their capacity to accelerate the rate of electron transfer on the electrode surface.…”

“…Thus, they can be utilized either alone or in a nanocomposite combination in the fabrication of sensors and biosensors. [23][24][25][26][27] The surface of MWCNTs can be easily modied by certain chemical groups that improve the electrochemical activity, reduce the surface fouling, and ease the polymerization reactions on their surface. 28 Carboxylation of the MWCNT surface improves the interaction with PANI and promotes the electrochemical properties of the nanocomposite.…”

Dy(iii)-coordination imprinted self-assembly microspheres based on a silica core for highly sensitive and selective detection of two carbamate pesticides

“…Surface-imprinted polymers have proven to be rapid and specic molecular recognition materials with the capacity for tailor-made exibility and spatial prearrangement. 15,16 Moreover, large specic recognition areas, swi binding kinetics, short analysis times, and easy template removal enable successful detection of pesticides, 17,18 fungicides, 19,20 glucose, 21 viruses, 22 and proteins 23,24 using surface-imprinted widgets. Recently, an MOF-based surface-imprinted probe was prepared by imprinting hepatitis A virus (HAV) onto the surface of a pH-responsive metal-organic framework (MIL-101) for selective determination of the templates within 20 min through resonance light scattering (RLS) with a linear response to concentrations of 0.02-2.0 nmol L −1 and a limit of detection (LOD) of 0.1 pmol L −1 .…”
