1. A method for identifying a product from a product library, wherein said product binds to a target, said method comprising:
- (a) preparing a nucleic acid-first reactant test mixture comprised of nucleic acids each having a region of randomized sequence and each being coupled to a first reactant consisting of a small organic molecule with a molecular weight in the range of 2 to 1000;
(b) reacting said nucleic acid-first reactant test mixture with a free reactant consisting of a small organic molecule with a molecular weight in the range of 2 to 1000 to form a product library comprised of products formed by the reaction of said first reactant and said free reactant, wherein said reaction is facilitated by the nucleic acid coupled to said first reactant;
(c) partitioning between members of said product library based on their ability to bind to said target; and
(d) identifying said products which bind to said target.

17. A method for identifying a product from a product library, wherein said product binds to a target molecule, said method comprising:
-
(a) preparing a nucleic acid-first reactant test mixture comprises of nucleic acids each having a region of randomized sequence and each being coupled to a first reactant consisting of a small organic molecule with a molecular weight in the range of 2 to 1000; (b) reacting said nucleic acid-first reactant test mixture with a free reactant consisting of a small organic molecule with a molecular weight in the range of 2 to 1000 to form a product library comprised of nucleic acids coupled to a product formed by the reaction of said first reactant and said free reactant; (c) partitioning said products having increased affinity to the target from the remainder of the product library; and (d) identifying said product from said library. - View Dependent Claims (18)

19. A method for identifying a facilitating nucleic acid, wherein said nucleic acid is selected for its ability to facilitate a reaction between a first reactant coupled to said nucleic acid and a free reactant, wherein each reactant is consisting of a small organic molecule with a molecular weight in the range of 2 to 1000, to form a product which binds to a target, said method comprising:
-
(a) preparing a nucleic acid-first reactant test mixture comprised of nucleic acids each having a region of randomized sequence and each being coupled to a first reactant; (b) mixing said nucleic acid-first reactant test mixture with a plurality of free reactants under conditions favorable for a nucleic acid facilitated reaction between said first reactant and said free reactant to form said product; (c) isolating members of said nucleic acid-first reactant test mixture which formed said products; and (d) identifying said facilitating nucleic acid.

20. A method for simultaneously identifying facilitating nucleic acids and producing a product library, wherein said facilitating nucleic acids facilitate the reaction between a first reactant and at least one free reactant, wherein each reactant is consisting of a small organic molecule with a molecular weight in the range of 2 to 1000, to form said product library, said method comprising:
-
(a) preparing a nucleic acid-first reactant test mixture comprised of nucleic acids each having a region of randomized sequence and each being coupled to said first reactant; (b) reacting said nucleic acid-first reactant test mixture with said free reactant to form a product library; and (c) identifying said facilitating nucleic acids.
