1. A method comprising:
- synthesizing a chemical array of single-stranded oligonucleotides on a substrate, wherein each of said single-stranded oligonucleotides comprises a cleavable linker comprising a silanol, wherein cleavage at said silanol releases the single-stranded oligonucleotides from the array to produce released single-stranded oligonucleotides, wherein both the 3′ and
5′
ends of all of the released single-stranded oligonucleotides are unsuitable as substrates for enzymatic reactions.

Abstract
A method for controlling the use of oligonucleotide sequences released from arrays, comprises synthesizing a chemical array of oligonucleotides on a substrate under conditions for producing an array of cleavable oligonucleotides that are blocked from enzymatic reactions after cleavage. Methods may also include receiving a chemical array of cleavable oligonucleotides on a substrate, and cleaving the oligonucleotides from the array, wherein the oligonucleotides are blocked from enzymatic reactions after cleavage. Arrays, populations of oligonucleotides and kits are also provided to facilitate the methods.

25. A method comprising:
synthesizing a chemical array of single-stranded oligonucleotides on a substrate, wherein each of said single-stranded oligonucleotides comprises a cleavage site, wherein cleavage at said cleavage site releases the single-stranded oligonucleotides from the array, wherein the 5′
ends of the single-stranded oligonucleotides are blocked with a blocking group that comprises a 5′
-OMe-nucleoside phosphoramidite, and wherein both the 3′ and
5′
ends of all of the released single-stranded oligonucleotides are unsuitable as substrates for enzymatic reactions.

26. A method comprising receiving a chemical array of cleavable single-stranded oligonucleotides on a substrate, and cleaving the single-stranded oligonucleotides from the array, wherein both the 3′
- and 5′
ends of all the cleaved single-stranded oligonucleotides are blocked from enzymatic reactions after cleavage from the array, wherein said cleavable single-stranded oligonucleotides are attached to said substrate via a cleavable linker that comprises a silanol, and the 5′
ends of the cleavable single-stranded oligonucleotides are blocked with a blocking group that comprises a 5′
-OMe-nucleotiside phosphoramidite.
