Peptide conjugated chitosan foam as a novel approach for capture-purification and rapid detection of hapten – Example of ochratoxin A

Chitooligosaccharide as A Possible Replacement for Sulfur Dioxide in Winemaking

“…This can inhibit the oxidation of wine constituents, including phenolics, certain metals, tyrosine, and aldehydes, during the winemaking process, while retaining the sensory and nutritional value of wine. Furthermore, as previously reported, adding COS-based materials can reduce the concentrations of metals, such as boron, lead, mercury, and antimony, and that of ochratoxin A in process water [24][25][26][27], which can markedly improve wine quality. Therefore, in this study, COS was applied as an alternative to SO 2 in winemaking, and the antimicrobial activity of COS during winemaking was investigated using our own separated contaminated organisms and known wine spoilage organisms in comparison with the action of SO 2 .…”

Removal of Cu(II) and tetracycline using an aromatic rings-functionalized chitosan-based flocculant: Enhanced interaction between the flocculant and the antibiotic

“…For example, Bratskaya et al dedicated themselves to the removal of heavy metal ions, discussing the potential of chitosan derivatives (Ncarboxyethyl chitosan, CEC) in the removal of heavy metals [Cu (II), Zn(II) and Ni(II)] from water by the flocculation/precipitation process [22]. Oladoja et al explored a novel magnetic macroreticulated cross-linked chitosan for the adsorption of tetracycline (TC) from aquatic systems and high removal efficiencies were achieved [23,24]. Although these studies dealing with single contaminant have achieved certain success, there is much fewer studies involved when the water contains more than one sort of contaminant, such as the coexistence of heavy metals and antibiotics.…”

Comparison of Electrochemical Immunosensors and Aptasensors for Detection of Small Organic Molecules in Environment, Food Safety, Clinical and Public Security

“…SPR analysis confirmed that the peptides bind to ochratoxin A with KD values of 10 to 15 μM. More recently, Solerai et al [ 65 ] reported another peptide conjugated chitosan foam for detection of OTA using enzymatic chemiluminescence. There is therefore no reason for electrochemical OTA sensors based on peptide probes not to appear in the literature in the forthcoming years.…”
