biostudies-literatureUnknown6(2)Bahavarnia FA novel micro-array was developed to a colorimetric detection of some amines, including histamine (HT), cadaverine (CAD), 1,4-diaminobutane (putrescine), 2-phenylethylamine (2-PEA), spermidine (SD) and ethylenediamine (EA) using silver nanoparticle (silver nanoprisms [AgNPrs]) as optical nanoprobe. This method relies on the chemical interaction between the TA-AgNPrs probe and candidate amines, resulting in observable colour changes. The interaction mechanisms were analysed using various techniques, including UV-visible spectrophotometry, naked-eye colorimetry dynamic light scattering spectroscopy and zeta potential measurements. The efficient interactions between the analytes and the optical probe are particularly observed at absorption conditions of 220-800 nm by a UV-visible spectrophotometry method. The designed chemosensor accurately detects various amines in the linear concentrations ranging of 1 µM to 50 mM. This analytical system has been successfully applied to analyse candidate amines in meat samples.Analytical science advancese70051https://www.ebi.ac.uk/biostudies/studies/S-EPMC12554353biostudies-literatureMicro-Scale Arrays Fabricated on Parafilm and Polymethyl Methacrylate Towards Differential Colorimetric Analysis of Amines via Shape Transformation of Ag Nanoprisms.PMC12554353Shadjou NEbrahimi RBahavarnia FHasanzadeh MfalseMicro-Scale Arrays Fabricated on Parafilm and Polymethyl Methacrylate Towards Differential Colorimetric Analysis of Amines via Shape Transformation of Ag Nanoprisms.A novel micro-array was developed to a colorimetric detection of some amines, including histamine (HT), cadaverine (CAD), 1,4-diaminobutane (putrescine), 2-phenylethylamine (2-PEA), spermidine (SD) and ethylenediamine (EA) using silver nanoparticle (silver nanoprisms [AgNPrs]) as optical nanoprobe.
