3.3.2.14	additional information	enzyme immobilization by biogenic silica encapsulation which is used to stabilize the enzyme and to enable it to be packed into a model microcolumn for application as a biosensor or as a bioreactor for continuous destruction of 2,4-dinitroanisole (DNAN). The immobilized enzyme is stable and not inhibited by other insensitive munitions constituents. The highly specific, convenient and robust biocatalyst DNAN demethylase can mineralize DNAN. An alternative method for DNAN detection involved coating the encapsulated enzyme on cellulose filter paper. Methods, detailed overview	753444
