摘要： Methods are disclosed for providing a library of composite compositions on a support. The method involves depositing one or more components onto the support on either discrete spaced regions of the support or as a continuous concentration gradients on the surface of the support. The composite samples can be removed from the support by drilling out portions of the coated support so as to yield individual composite tablets containing the support with one or more component layers thereon. By using this method, a vast number of composites can be made and tested simultaneously.

摘要： Methods are disclosed for providing a library of composite or novel composition samples on a support. The method involves depositing one or more components as concentration gradients on the surface of the support. The concentration gradients are placed on the support in the form of superimposed triangles which allow ready formation of composite or composition samples containing three or more components. The samples can be removed from the support by drilling out portions of the coated support so as to yield individual tablets containing the support with one or more component layers thereon. By using this method, a vast number of samples can be made.
