detection of Al3+ ions in complex matrices has been developed. The method was based on using chitosan (CHIT) biopolymer/magnetite nanoparticles (MGNPs) functionalized with 8-hydroxyquinoline sulfonic acid (8-HQS) in the presence of Al3+ ions to synthesize a magnetite ion non-imprinted biopolymer (MGINIBP) chemosensor. This newly developed chemosensor was synthesized via polymerization of CHIT with [3-(2
A dry analytical element comprising at least one water-permeable reagent layer and a porous spreading layer laminated in this order on a support, wherein at least one layer which is the water-permeable reagent layer, the porous spreading layer or an optional water-permeable layer contains a water-soluble polybasic amino carboxylic acid which is an ampholyte.
By applying an analytical element of the invention, an analyte can be measured at a high sensitivity using a small amount of an enzyme, etc., and shelf file can be extended.
