1. A method of placing at least one biological reagent at a plurality of locations on a substrate, the method comprising the steps of:
- providing a stamp member having a plurality of projected portions, each of the projected portions having at least one cavity therein;
applying the at least one biological reagent to the stamp member; and
contacting the stamp member with the substrate to transfer the at least one biological reagent from the stamp member to the plurality of locations.

Abstract
An apparatus for placing at least one biological reagent at a plurality of locations on a substrate includes a stamp member onto which the at least one biological reagent is applied. The stamp member defines a plurality of transfer elements patterned to correspond to the plurality of locations. The stamp member contacts the substrate to transfer the at least one biological reagent from the plurality of transfer elements to the plurality of locations. The transfer elements can be defined by reservoirs or projected portions of the stamp member. A method of using said apparatus is also disclosed.
