REDRAWN CAPILLARY IMAGING RESERVOIR

摘要

Methods and apparatus for depositing a high density biological or chemical array onto a solid support. Specifically, the apparatus is made up of a plurality of open ended channels (12) collectively forming a matrix. The matrix has been redrawn and cut such that the pitch of the channels (12) on the loading end is larger than the pitch of the channels (12) on the liquid delivery end. The upper portion of each channel serves as a reservoir, while the opposing end, which has been formed by the redrawing process, is diametrically sized such that liquid in the reservoir is retained by capillary pressure at the delivery end. At any point along the height of the capillary reservoir device (10), all cross-sectional dimensions and areas are uniformly reduced.
