Abstract:
A method for screening a fluid sample at least suspected of containing a nucleic acid, for said at least suspected nucleic acid, by depositing a quality of said fluid sample onto a nucleic acid array comprising a plurality of nucleic acids stably attached onto an array surface, said method comprising:positioning a thermal inkjet head filled with said at least suspected nucleic acid containing fluid sample in opposing relation to said array surface; actuating said thermal inkjet head in a manner sufficient to expel said quantity of fluid sample onto said array surface to deposit said quantity of fluid sample on said array surface, wherein nucleic acids present in said deposited fluid are capable of hybridizing to their nucleic acid complement; and detecting any binding complexes on said array surface between any nucleic acids present in said fluid sample and any nucleic of said array to screen said sample for said at least suspected nucleic acid.
