  Piezoelectric pH sensors: AT-cut quartz resonators with amphoteric polymer films

  摘要：

  Piezoelectric AT-cut quartz resonators immersed in aqueous media, coated with cross-linked films of the random copolymer-{[CH2CH(CO2H)]a-[CH2-C(CH3)(CO2CH3)]b-[CH2C(CH3)(CO2CH2CH2-NMe2)]c}n (1), exhibit large frequency changes when the pH is changed in the vicinity of the isoelectric point of the polymer film. The frequency changes are attributed to changes in the viscoelastic properties of the films that occur during phase transitions between the isoelectric form and the cationic polymer (1-NMe2H+) present at low pH or the anionic polymer (1-CO2-) present at high pH. These phase transitions are accompanied by dramatic changes in acoustic energy attenuation, film thickness changes, and film surface energy, as indicated by acoustic impedance analysis, phase measurement interferometric microscopy, and contact angle measurements. The results are consistent with pH-dependent segregation of the isolectric and ionic phases within the bulk and between the bulk and the surface. The unique pH-sensing capabilities of the coated resonators, combined with their robustness, ease of fabrication, and low cost, provide a convenient approach for the measurement of ''threshold'' pH changes. Real-time measurements of enzymatic activity and microbe metabolism are demonstrated as examples of potential applications of these sensors.

  (EN) A lipase or lipase isozyme from $i(Candida rugosa) is used to stereoselectively hydrolyze esters, esterify acids or transesterify esters in aqueous/organic systems. Esters of 2-substituted acids such as 2-(4-hydroxyphenoxy) propionic acid, where the acid is not substituted at the 2-position with halogen, are hydrolyzed at high enantiomeric excess in the presence of an organic solvent. A reducing agent may be present to prevent oxidation of the acid and its esters. Two lipase isozymes are purified from $i(Candida rugosa) by ion exchange chromatography or isoelectric focusing, and are used for stereoselective hydrolysis of esters, esterification of acids or transesterification of esters. The lipase or lipase isozyme may be immobilized, and immobilization is improved by the presence of polyvinyl alcohol or an organic acid such as stearic acid. The presence of a fatty acid or fatty acid ester during lipase reaction increases the rate or stereoselectivity of the reaction.(FR) Une lipase ou une isozyme de lipase venant de $i(Candida rugosa) est utilisée pour hydrolyser stéréosélectivement des esters, estérifier des acides ou transestérifier des esters dans des systèmes aqueux/organiques. Des esters d'acides substitués en position 2 tels que l'acide 2-(4-hydroxyphénoxy) propionique, où l'acide n'est pas substitué dans la position 2 avec l'halogène, sont hydrolysés à un excès énantiomère élevé en présence d'un solvant organique. Un agent réducteur peut être présent pour empêcher l'oxydation de l'acide et de ses esters. Deux isozymes de lipases sont purifiées à partir de $i(Candida rugosa) par chromatographie par échange d'ion ou focalisation isoélectrique, et sont utilisés pour l'hydrolyse stéréosélective d'esters, l'estérification d'acides ou la transestérification d'esters. La lipase ou lisozyme de lipase peut être immobilisée, et l'immobilisation est améliorée par la présence d'alcools polyvinyliques ou d'un acide organique tel que l'acide stéarique. La présence d'un acide gras ou d'un ester d'acide gras pendant la réaction de la lipase augmente le taux ou stéréosélectivité de la réaction.
