Rapid quantitative detection of luteolin using an electrochemical sensor based on electrospinning of carbon nanofibers doped with single-walled carbon nanoangles

Abstract

In this study, single-walled carbon nanoangles/carbon nanofibers (SWCNHs/CNFs) were synthesized by electrospinning, followed by annealing in N2 atmosphere. The synthesized composite was structurally characterized by scanning electron microscopy, transmission electron...

Plain-Woven Areca Sheath Fiber-Reinforced Epoxy Composites: The Influence of the Fiber Fraction on Physical and Mechanical Features and Responses of the Tribo System and Machine Learning Modeling

“…Silk fibroin from Bombyx mori silk was combined with an epoxy resin polymer system to study molecular interactions at the silk fiber−matrix interface. 31 Zhang et al 32 investigated steel fiber-reinforced concrete (SFRC), ordinary concrete (OC), and carbon fiber-reinforced plastic (CFRP) plates to create a composite beam. Tests examined the flexural behavior of eight specimens comprising four CSOCBs and four SFRC-OC composite beams.…”

“…Tests examined the flexural behavior of eight specimens comprising four CSOCBs and four SFRC-OC composite beams. SWCNHs/CNFs were synthesized via electrospinning and N 2 annealing, and their structure was characterized using SEM, TEM, and XPS . Three epoxy resin matrices with different cross-linking structures were reinforced with Bombyx mori silk.…”

Development of homogeneous dispersive solid phase extraction using albumin as a green sorbent and its combination with dispersive liquid–liquid microextraction: application in extraction of pesticides from fruit juices

“…In spite of the significant efficiency of SPME in the extraction of different compounds, DμSPE has attracted important attention due to preparation and use of different compounds as sorbents in the extraction procedure. 7 Various types of sorbents such as carbon nanotubes, 8 graphene, 9 hierarchical SnO 2 , 10 molecularly imprinted polymers, 11 covalent organic frameworks, 12 metal–organic frameworks, 13 etc. have been used in determination approaches.…”

Surface modification of a screen-printed electrode with a flower-like nanostructure to fabricate a guanine DNA-based electrochemical biosensor to determine the anticancer drug pemigatinib

“…11–13 However, DNA immobilization affects the biosensor selectivity, as the diffusion of various substrates through the immobilization matrix is influenced by the immobilization material and the hydrophilicity of the microenvironment. 14–19 Moreover, the immobilization of DNA on supports might induce steric hindrances for some substrates or inhibitors. However, immobilization on nanomaterials can reduce the applied potential and minimize interferences.…”
