Medientyp: E-Artikel Titel: Modulated molecular recognition by a temperature‐sensitive molecularly‐imprinted polymer Beteiligte: Li, Songjun; Pilla, Srikanth; Gong, Shaoqin Erschienen: Wiley, 2009 Erschienen in: Journal of Polymer Science Part A: Polymer Chemistry, 47 (2009) 9, Seite 2352-2360 Sprache: Englisch DOI: 10.1002/pola.23325 ISSN: 1099-0518; 0887-624X Entstehung: Anmerkungen: Beschreibung: AbstractModulated molecular recognition was achieved in a temperature‐sensitive molecularly‐imprinted polymer. Using PNIPA as the temperature‐sensitive element, the adenine‐imprinted polymer (i.e., MIP‐S) was prepared and characterized. The MIP‐S exhibited a temperature‐responsive molecular recognition behavior because of the thermal phase‐transition within the MIP‐S network. Specifically, below the transition temperature (e.g., 20 °C), the MIP‐S showed a highly specific recognition for the imprint species (adenine). However, the MIP‐S did not show any significant resolution for the imprint species (adenine) and its analogue (1‐methyladenine) above the transition temperature (e.g., 40 °C). Such temperature‐regulated recognition is comparable to a switch‐on and switch‐off process, thereby making tunable molecular recognition feasible. © 2009 Wiley Periodicals, Inc.
