Abstract
The present invention discloses a biochip comprising a substrate and a three-dimensional mesoporous layer on top of it, wherein the mesoporous layer on top is chemically modified to recognize labeling DNAs, proteins, peptides, saccharides, and cells. In addition, this invention also discloses a method for forming the biochip with a three-dimensional mesoporous layer, including a blending process, a heating process, a coating process, a gelation process, a drying process, and a surface modification process.
Claims9
A biochip with a three-dimensional mesoporous layer, comprising:
- a substrate covered with a three-dimensional mesoporous aerogel layer, wherein said three-dimensional mesoporous aerogel layer is formed by coating a precursor solution that comprises an ionic liquid and at least one alkoxide monomer and/or aryloxide monomer and then performing a gelation process where the precursor solution comprises the ionic liquid about 20˜50 wt % of the at least one alkoxide monomer and/or aryloxide monomer;
- the surface of said three-dimensional mesoporous aerogel layer is modified by a modifier that is an alkoxide monomer and/or aryloxide monomer with at least one specific moiety;
- said specific moiety comprises one selected from the group consisting of the following:
- amine group, hydroxyl group, carboxyl group, and epoxy group;
- a converter having a first moiety and a second moiety is linked with the specific moiety so as to have the surface of said three-dimensional mesoporous layer having the second moiety;
- wherein the substrate is silicon chip, glass, or polymer;
- and the porosity of said three-dimensional mesoporous layer ranges about 50% to 90%.
