Establishment of magnetic beads-based enzyme immunoassay for detection of chloramphenicol in milk

A novel “dual-potential” electrochemiluminescence aptasensor array using CdS quantum dots and luminol-gold nanoparticles as labels for simultaneous detection of malachite green and chloramphenicol

“…The current analytical methods to detect these residues include gas chromatography-mass spectrometry (Basheer et al, 2005;Ma et al, 2013), liquid chromatography-mass spectrometry (Sniegocki et al, 2014;Mitani et al, 2005), enzyme-linked immunoassay (Xu et al, 2012;Kondo et al, 2012), raman 4 microfluidic sensor (Ji et al, 2015), chemiluminescent immunoassay , electrochemical method , and electrochemiluminescence (ECL) method (Fei et al, 2014;Muzyka et al, 2014). Among these methods, ECL has become one of the predominant analytical techniques because of its simple instrumentation, high sensitivity, and wide dynamic range (Feng et al, 2014).…”

Revisiting 30 years of biofunctionalization and surface chemistry of inorganic nanoparticles for nanomedicine

“…In fact, magnetic separation of red blood cells using magnetic microspheres was reported as early as 1977 (Molday et al, 1977). MNPs are used to purify and concentrate different types of analytes in complex samples, such as hormones in biological samples, antibiotics or bacteria in food (Kuo et al, 2012; Svobodova et al, 2012; Xu et al, 2012). One of the best known systems that employ MNPs for separation and concentration is the bio-bar code technology originally described by Nam et al (2003).…”

A label-free photoelectrochemical aptasensor based on nitrogen-doped graphene quantum dots for chloramphenicol determination

“…However, CAP is suspected to be carcinogenic and has potential lethal side effects on human beings, such as leukemia, aplastic anemia and grey baby syndrome (Wilson et al, 1987), and thus it is mainly limited to be used as a low-priced and effective veterinary drug (Xu et al, 2012). Due to the effluent from livestock wastes, CAP has been frequently detected in rivers, municipal sewage and sediment, which may cause ecological risks (Choi et al, 2008;Liu et al, 2009).…”

“…Moreover, CAP residues have been found in various animal-derived foods such as meat, egg, honey and milk (Xu et al, 2012). The minimum required performance limit (MRPL) for CAP residues in food of animal origin was set to be 0.3 μg kg -1 by the European Union (EU) (Karaseva and Ermolaeva, 2012).…”
