Three-dimensional arrayed amino aerogel biochips for molecular recognition of antigens.

The three-dimensional (3D) biochips prepared in this study are composed of a glass microscopy slide arrayed with amino aerogel dots. The amino aerogel was produced using the sol-gel process, with an ionic liquid as the template followed by a solvent extraction to remove the template and build a three-dimensional mesoporous structure. The FTIR spectrum verified that the major template was removed and the (29)Si solid-state NMR spectra recognized the cross-linkages in the SiO(2) network structure.
