“…Thiourea is usually preferred to urea because of less self association [23]. It is known that pH influences the binding of allylthioureas to phosphates with a maximum reached at about pH 2.5 [21]. In an MIP, better rebinding was observed at pH 4.5 than 7.5 [22].…”

In order to mimic recognition properties of adenylate kinase, molecularly imprinted polymers (MIPs) were prepared for adenosine 5'-monophosphate (AMP), a substrate of the enzyme. Different functional monomers interacting with the phosphate moiety were tested, and the MIP giving the best specific binding of AMP was composed with one equivalent of 2-(dimethylamino)ethyl methacrylate and ten equivalents of acrylamide compared to AMP. Packed into solid phase cartridge, this polymer showed similar characteristics than the enzyme, since it was specific for AMP toward other nucleotides.

“…Unfortunately, in this interesting paper, polymerization was achieved in solvents unable to dissolve AMP. Phosphate ion was also recovered selectively from aqueous media with polymer imprinted for phenylphosphonic acid with allythiourea as functional monomer [21,22].…”

“…In this technique, a mixture of target molecules (template) and a monomer are polymerized, with subsequent removal of the template which results in the formation of a cavity to allow binding of a target analyte (Kugimiya and Takei 2006). For phosphate ions, a number of molecularly imprinted polymers (MIPs) based on thiourea groups have been developed, but their application in designing phosphate biosensors is still lagging (Warwick et al 2013).…”

A number of biosensors have been developed for phosphate analysis particularly, concerning its negative impact within the environmental and biological systems. Enzymatic biosensors comprising either a single or multiple enzymatic system have been extensively used for the direct and indirect analysis of phosphate ions. Furthermore, some non-enzymatic biosensors, such as affinity-based biosensors, provide an alternative analytical approach with a higher selectivity. This article reviews the recent advances in the field of biosensor developed for phosphate estimation in clinical and environmental samples, concerning the techniques involved, and the sensitivity toward phosphate ions. The biosensors have been classified and discussed on the basis of the number of enzymes used to develop the analytical system, and a comparative analysis has been performed.

“…We have previously reported that the phosphate imprinted polymers prepared with 1-allyl-2-thiourea as the functional monomer and the imprinted polymers showed high affinity for phosphate in aqueous media (Kugimiya et al 2006). In the present article, the functional monomer with thiourea derivative was synthesized with the aim of improving the selectivity of the imprinted polymer, and the selective recovery of phosphate from river water was evaluated.…”

Phosphate-selective molecularly imprinted polymers were prepared using N-allyl-N 0 -methyl-thiourea or 1-allyl-2-thiourea as functional monomers, and the binding ability and selectivity of the polymers were evaluated. River water collected from agricultural use was the test sample. Though the water included some impurities, 65% of the phosphate was recovered from the imprinted polymer prepared using Nallyl-N 0 -methyl-thiourea as the functional monomer, while on the other hand, the binding of other anions was scarcely low. The imprinted polymer showed selective binding to phosphate and indicated the phosphate recovery material from river water.
