Synthesis of nitrogen-doped graphene nanosheets decorated with gold nanoparticles as an improved sensor for electrochemical determination of chloramphenicol

A sensitive fluorescent nanosensor for chloramphenicol based on molecularly imprinted polymer‐capped CdTe quantum dots

“…Therefore, monitoring of CAP levels in biological samples and food products is highly important. Various methods have been developed for this purpose, including chemiluminescence , voltammetry and chromatographic methods using fluorescence immunochromatography , gas chromatography–mass spectrometry (GC‐MS) and liquid chromatography–tandem mass spectrometry (LC–MS/MS) .…”

A “signal-on’’ aptasensor for simultaneous detection of chloramphenicol and polychlorinated biphenyls using multi-metal ions encoded nanospherical brushes as tracers

“…These traditional separation-based methods are sensitive, reliable and stable, but their high cost and complicated operation limit their application. Electrochemical biosensor has attracted considerable attention for its intrinsic advantages, such as, rapid response, ease to use, inexpensive instrumentation Pilehvar et al, 2012;Borowiec et al, 2013;Pilehvar et al, 2014), which can also be employed in simultaneous determination by using several signal tracers . However, to find high-sensitive and distinguishable multi-tracers is the key issue to achieve simultaneous analysis in the electrochemical assay.…”

The applications of conductive nanomaterials in the biomedical field

“…Carbon‐based nanomaterials, including graphenes, carbon nanotubes (CNTs), nanowires, and nanoribbons, have been used as biomaterials. Among them, CNTs are generally classified as single‐walled, doubled‐walled, or multi‐walled structure nanotubes . Especially, CNTs show the remarkable ability to direct stem cell differentiation and could act as extracellular matrix to offer favorable environment to induce cellular attachment and growth .…”

“…It is known that nanoscale metals possess a better orientation as well as large and porous surface areas, and excellent conductivity. For example, gold nanoparticles (AuNPs) have been extensively applied in biomedicine owing to their large surface area, high surface free energy and good biocompatibility …”
