Man, Yan;Ren, Junan;Li, Bingru;Jin, Xinxin;Pan, Ligang research published 《 A simple, highly sensitive colorimetric immunosensor for the detection of alternariol monomethyl ether in fruit by non-aggregated gold nanoparticles》, the research content is summarized as follows. Alternariol monomethyl ether (AME) is one of the major Alternaria mycotoxins present in a wide range of fruits, vegetables, grains, and their products, and possesses the properties of mutagenicity and carcinogenicity. In this study, a simple, rapid, and highly sensitive colorimetric immunosensor based on magnetic nanoparticles (MNPs) was firstly developed for the detection of AME in fruit by nonaggregated gold nanoparticles (GNPs). AME-BSA-Fe3O4 MNP conjugates and free AME mols. in samples competitively bind with monoclonal antibody (mAb)-GNP conjugates. After magnetic separation, the UV absorbance of the nonaggregated GNP supernatant was measured directly. The absorption intensity was proportional to the concentration of AME in the sample. Carboxyl-group-modified AME, AME-bovine serum albumin (BSA) conjugates, anti-AME mAbs, AME-BSA-Fe3O4 MNP conjugates, and mAb-GNP conjugates were prepared and characterized. The effect of GNP sizes (16, 24, and 40 nm) on the colorimetric determination of AME was studied. Under optimized conditions, the limit of detection and the linear range for AME were 0.16 ng/mL and 0.08-0.48 ng/mL, resp. Moreover, the colorimetric immunosensor developed has lower cross-reactivity with AME analogs. The recoveries of spiked fruits ranged from 80.6% to 90.7%. The colorimetric immunosensor developed provides a promising method for simple, rapid, highly sensitive, and highly specific detection of other mycotoxins in the field of food safety.

Formula: C5H9BrO2, Methyl 4-bromobutyrate,also as known as 4-Bromobutyric acid methyl ester, is a useful research compound. Its molecular formula is C5H9BrO2 and its molecular weight is 181.03 g/mol. The purity is usually 95%.
4-Bromobutyric acid methyl ester is a synthetic compound that can be used to inhibit the activity of the G1 phase cyclin-dependent kinases. It has been shown to inhibit protein synthesis by alkylating the amino groups of proteins and fatty acids. 4-Bromobutyric acid methyl ester also inhibits the growth of cancer cell lines, such as renal carcinoma cells. The mechanism of action for this drug is not well understood, but it may be due to its ability to bind with monoclonal antibodies and enter kidney cells by passive diffusion., 4897-84-1.
