1. A method of forming a line of sample on a surface, the method comprising the steps of:
- (a) forming a contact between a reaction surface on a reaction substrate and an open microfluidic channel on a channel substrate;
(b) introducing a sample solution into the microfluidic channel, wherein the sample solution contacts the reaction surface along a contact line formed by the contact between the reaction surface and the open microfluidic channel; and
, (c) disrupting the contact between the reaction surface and the microfluidic channel, thereby forming a line of sample on the reaction surface, wherein the line corresponds to the contact line.
