... the polymer matrix provides the enzyme with a microenvironment which may differ in many respects(e. g. pH, substrate concentration) from the solvent in which the immobilized enzyme is suspended.... An interesting proposed analytical application is the use of enzymes as "molecular probes" for determining the microenvironment of supports(water-soluble or water-insoluble). Because an immobilized enzyme will behave in accordance with its local environment, a determination of specific enzymic properties(usually activity) can reveal the nature of its immediate environment.  2, record 2, English, - molecular%20probe

Textiles - Détermination du pH de l'extrait aqueux. La valeur du pH de l'extrait aqueux d'un textile constitue une indication très utile sur l'histoire des traitements subis par celui-ci. En outre, il devient plus courant d'exiger que le textile, sous ses différentes formes, satisfasse à certaines limites d'acidité ou d'alcalinité, lesquelles sont souvent exprimées sous forme du pH de l'extrait aqueux. La présente Norme internationale spécifie une méthode de détermination de la valeur du pH de l'extrait aqueux des textiles.
