In this study, chitosan [(1 --> 4) linked 2-amino-2-deoxy-beta-D-glucopyranose] beads were prepared by interacting this polycation (> 90% deacetylated) with the tripolyphosphate (TPP) polyanion. The resulting chitosan-TPP beads (C) were mod...
MRI virtual biopsies: analysis of an explanted endovascular device and perspectives for the future [0.03%]
无创评价血管内移植物的磁共振虚拟活检:现状和未来展望
R Guidoin,Z Zhang,Y Douville et al.
R Guidoin et al.
Information that can be obtained by magnetic resonance imaging (MRI) of explanted endovascular devices must be validated as this method is non-destructive. Histology of such a device together with its encroached tissues can be elegantly per...
An amperometric enzyme electrode for creatine determination prepared by the immobilization of creatinase and sarcosine oxidase in poly(vinylferrocenium) [0.03%]
安培法酶电极用于肌酸测定:聚乙烯基铁腐烯中次没食子酸硬脂酸酯和肌酸氧化酶的固定化
