1. An array composition comprising:
- (a) a rigid support;
(b) a molded layer with at least a first assay location comprising discrete sites, wherein said molded layer is adhered to said rigid support;
(c) a layer of bonding agent adhering said rigid support to said molded layer; and
(d) a population of microspheres comprising at least a first and a second subpopulation, wherein said first subpopulation comprises a first bioactive agent and said second subpopulation comprises a second bioactive agent wherein said microspheres are randomly distributed on said sites.

15. A method for making an array composition containing at least a first assay location having discrete sites comprising the steps of:
-
(a) contacting a surface of a template structure, said surface comprising one or more sets of projections, with a moldable material;
(b) removing said moldable material from said surface of said template structure, whereby said removed moldable material forms a molded layer with at least a first assay location comprising discrete sites;
(c) adhering said molded layer to a rigid support; and
(d) randomly distributing microspheres on said molded layer such that individual discrete sites comprise microspheres, wherein said microspheres comprise at least a first and a second subpopulation, wherein said first subpopulation comprises a first bioactive agent and said second subpopulation comprises a second bioactive agent.
