Patent ID: 7150859

Claim:
A device for manufacturing microarrays comprising: electro-spraying means for electrostatically spraying, in sequence, a plurality of solutions each containing respective one of a plurality of kinds of biologically active samples; supporting means for supporting a plurality of sample chips on which samples contained in the solutions and electrostatically sprayed from said electro-spraying means are deposited; masking means disposed between said electro-spraying means and said supporting means and having holes whose number is equal to the number of the sample chips, a sample being selectively and simultaneously deposited on said sample chips at predetermined corresponding locations, wherein the masking means is formed by sequentially laminating a first insulating layer, an electrically conductive layer, a second insulating layer and a mask layer; and shifting means for shifting said supporting means and said masking means relatively such that the samples are deposited on said plurality of sample chips to manufacture simultaneously a plurality of microarrays.
