“…In other words, the result indicated that dicationic compounds became a pseudo crosslinkage by pulling close anionic groups in hydrogel. The hydrogels can retain the specific compounds through the effect of the molecular recognition resulting the hydrogel itself change the volume. Similar phenomenon was also observed in the VBTMAC hydrogel [Fig.…”

“…To solve the drawback, we expected that the strongly ionic groups such as a sulfonic acid and alkyl ammonium should be suitable for novel hydrogels enabling the swelling/shrinking characteristics at wider pH range. Previously, we reported the interval immobilization techniques as a novel molecular recognition technique based on the molecular imprinting . This technique indicated that the recognition sites with a high association constant can be constructed through the two‐point recognition of the functional groups on a target molecule.…”

To synthesize the novel molecular‐ and pH‐stimulus‐responsive hydrogel, we prepared poly(ethylene glycol)‐based hydrogel containing ionic groups. We evaluated the fundamental swelling/shrinking properties of the hydrogels synthesized by various conditions. Decreasing the molecular weight of a crosslinker provided the increasing of the equilibrium swelling ratio. Also, the equilibrium swelling ratio was changed by the introduction of functional ionic monomers and its compositions. Furthermore, the swelling/shrinking behaviors of the hydrogels were affected by the environmental condition of aqueous solution, in fact the hydrogels were considerably shrunk (to one‐fifth volume) using a di‐ionic solute in the aqueous solution through the ionic interactions between the hydrogel and the solutes. Additionally, the specific shrinking to diamine compounds was also observed in response to pH change. These results clearly show the swelling/shrinking responsibility of the hydrogels toward the molecular recognitions and its pH conditions. © 2013 Wiley Periodicals, Inc. J. Polym.

SummaryHerein we present a survey of the literature covering the development of molecular imprinting science and technology over the years 2004 to 2011. In total, 3779 references to the original papers, reviews, edited volumes and monographs from this period are included, along with recently identified uncited materials from prior to 2004 which were omitted in the first instalment of this series covering the years 1930 to 2003. 1 In the presentation of the assembled references, a section presenting reviews and monographs covering the area is followed by sections describing fundamental aspects of molecular imprinting including the development of novel polymer formats. Thereafter, literature describing efforts to apply these polymeric materials to a range of application areas is presented. Current trends and areas of rapid development are discussed.2

[43][44][45][46][47][48][49] In this review, we present the fundamental concepts of both techniques and their applications for environmental analyses, a photocatalysis, and a stimulus response hydrogel.…”
