摘要:已研究了在稀酸性水溶液(ph 3.35-4.50)中乳酸对afb(1)还原为afb(2)和afg(1)还原为afg(2)的动力学随乳酸浓度的变化,Afb(1),Afg(1)和37oc的氢离子.发现反应速率相对于乳酸和黄曲霉毒素的浓度为一阶,并且与氢离子浓度无关.用涉及初始形成的瞬态氧鎓中间体的机理解释了实验结果,该中间体倾向于极化烯烃(c = C)碳,这反过来导致速率确定步骤中从乳酸的α-碳原子提取氢化物.

摘要:A highly sensitive technology enabling selective recognition of aflatoxins such as in contaminated cereal samples. Methods for the synthesis of AgNP-containing MIP membranes from the monomer mixtures containing both methacrylate monomers and oligomers as well as AgNOs solution in dimethylformamide enable the detection system. The AgNP were formed in the structure of the polymeric membranes during the pre-heating step followed by the UV-initiated polymerization. The highly selective sensor elements where MIP membranes are combined with the Ag nanostructures as signal amplifiers (LSPR-MIP nanochips) can be stored separately and used with a simple optical recognition system as selective elements of point-of-care sensor devices, even in in-field conditions. Composite plasmonic membranes provide both highly selective recognition of the target toxin and the generation of an enhanced optical signal, allowing aflatoxin B1 detection at ultralow concentrations.
