METHOD AND APPARATUS FOR DEPOSITING A BIOLOGICAL FLUID ONTO A SUBSTRATE

摘要

There is described a method for depositing at least one biological fluid onto a surface (12) of a substrate (10), the method comprising the steps of (i) providing at least one thermal bubble-jet printhead (T1, T2, T3) loaded with at least one biological fluid, (ii) positioning the printhead (T1, T2, T3) next to the substrate, and (iii) supplying the printhead (T1, T2, T3) with energy thereby depositing the biological fluid onto the surface (12). The printhead (T1, T2, T3) is supplied with an energy E such that E > 1.6*Eth where Eth is the threshold energy of the printhead (T1, T2, T3). There are also described an apparatus (DA) for depositing at least one biological fluid onto a surface (12) of a substrate (10) and a microarray (MA) obtained by carrying out the depositing method.
