Electrochemical sensor based on molecularly imprinted polymer film via sol–gel technology and multi-walled carbon nanotubes-chitosan functional layer for sensitive determination of quinoxaline-2-carboxylic acid

Molecularly imprinted polymeric micro- and nano-particles for the targeted delivery of active molecules

“…MI functionalization can be obtained before or during the preparation of the composite system. Examples of electrochemical sensors for drugs [81,83,[85][86][87][88], glucose [89], parabens [90], neurotransmitters [82,91], alkaloids [83], pesticides [92] are reported in literature following this approach.…”

Au nanoparticles as one of the new promising materials were used to modify electrodes.…”

Development of a novel dual-functional lateral-flow sensor for on-site detection of small molecule analytes

“…At present, a variety of techniques have been employed to detect small molecules, including gas chromatography-mass spectrometry (GC-MS) [1], liquid chromatography-mass spectrometry (LC-MS and LC-MS/MS) [2], electrochemical sensors [3][4][5], plasmonic nanosensors [6,7], enzyme-linked immunosorbent assay (ELISA) [8], aptamers-based sensors [9], molecularly imprinted polymers (MIPs) [10], microfluidic [11,12], surface plasmon resonance (SPR) immunosensors [13], surface-enhanced Raman spectroscopy (SERS) sensors [14], etc. Most of the analytical techniques are specific and highly sensitive; however, they are too time consuming, laborious and complicated, requiring a professional staff and expensive equipment to enable to detect analytes.…”
