A series of amylases were encapsulated within silica matrices taking into account the nature of the amylase: α-amylase (Bacillus subtilis), α-amylase (Aspergillus oryzae), and β-amylase (barley), and the nature of the organosilane (alkyl-, amine- and mercaptan-based organosilanes). The results for the biocatalytic activity were shown to be dependent on the nature of the encapsulated enzymes and on the nature of the employed organosilane. Organosilanes containing the amine group showed different effects and lower biocatalytic conversions (on average). In general, β-amylase increased in biocatalytic activity after encapsulation. There was a strong correlation between the nature of the organosilane and the resulting porosity of the matrix as well as the reducing sugars produced from the saccharification tests. The lower the particle radius of gyration and the higher degree ramification of the secondary particles, the higher the catalyst bioactivity was. Generally, glucose production during saccharification was favored by the encapsulation of the enzyme.

考虑到淀粉酶的性质，一系列淀粉酶被封装在硅胶基质中：α-淀粉酶（枯草芽孢杆菌），α-淀粉酶（米曲霉）），β-​​淀粉酶（大麦）以及有机硅烷（基于烷基，胺和硫醇的有机硅烷）的性质。已显示出生物催化活性的结果取决于所包封的酶的性质以及所使用的有机硅烷的性质。含有胺基的有机硅烷显示出不同的效果，并具有较低的生物催化转化率（平均）。通常，包封后β-淀粉酶的生物催化活性增加。有机硅烷的性质与基质的孔隙率以及糖化试验产生的还原糖之间存在很强的相关性。回转的颗粒半径越小，次级颗粒的分枝度越高，则催化剂的生物活性越高。通常，
