Abstract
Official abstract text for this publication.
There is described a method for depositing at least one biological fluid onto a surface of a substrate, the method comprising the steps of (i) providing at least one thermal bubble jet printhead loaded with at least one biological fluid, (ii) positioning the printhead next to the substrate, and (iii) supplying the printhead with energy thereby depositing the biological fluid onto the surface. The printhead is supplied with an energy E such that E >1.6* E th where E th is the threshold energy of the printhead. There are also described an apparatus for depositing at least one biological fluid onto a surface of a substrate and a microarray obtained by carrying out the depositing method.
First claim
Opening claim text (preview).
The invention claimed is: 1. A method for depositing at least one biological fluid onto a surface of a substrate, said method comprising the steps of: a) loading at least one thermal bubble-jet printhead with at least one biological fluid; b) positioning said at least one printhead next to said substrate; and c) depositing said at least one biological fluid onto said surface by supplying energy E to said at least one printhead, wherein E> 1.6 *E th and E th is t…
