1. A method of producing an array of single molecules, comprising:
- a) providing a sample and an array, said sample comprising a molecules of target analyte in a concentration, said array comprising at least 1000 sites, each site having a defined volume between 10 attoliters and 50 picoliters; and
b) contacting said array with said sample such that the ratio of molecules of target analyte to each site of said array is less than 1;
1, so as to produce an array comprising sites containing single molecules.

45. A method of detecting a target analyte in a sample, the method comprising:
-
a) providing a sample and an array, said sample comprising a biomolecule target analyte in a first concentration, said array comprising at least 10,000 sites, each site having a defined femtoliter volume; b) diluting said sample to create a diluted sample, said diluted sample comprising a biomolecule target analyte in a second concentration; c) contacting said array with said diluted sample such that the ratio of biomolecule target analyte to each site of said array is between 1;
5 and 1;
500; andd) determining the number of sites of said array which contain a single biomolecule.
