Abstract
The disclosed methods, apparatus and compositions are of use for nucleic acid sequencing. More particularly, the methods and apparatus concern sequencing single molecules of single stranded DNA or RNA by exposing the molecule to exonuclease activity, removing free nucleotides one at a time from one end of the nucleic acid, and identifying the released nucleotides by Raman spectroscopy or FRET.
