Abstract:
1. A method for fabricating a biomolecule substrate, comprising the steps of: 1) providing a set of biomolecules and a substrate; 2) preparing biomolecule microcapsules by i) producing, from a main solution, an emulsion comprising a medium and micro-emulsion particles containing an intended biomolecule from the set of biomolecules on the biomolecule-type-by-biomolecule-type basis and ii) producing a polymer thin film by interfacial polycondensation at an interface between the micro-emulsion particles and the medium so that the micro-emulsion particles are covered with the polymer thin film, thereby obtaining the biomolecule microcapsules; 3) dispersing the biomolecule microcapsules into a sub-solution; 4) spraying the sub-solution containing the biomolecule microcapsules onto the substrate; and 5) setting the temperature of the sub-solution containing the biomolecule microcapsules during spraying to be higher than the melting point of the polymer thin film.
