1. A method for analyzing microRNA in a sample, comprising:
- a) hybridizing a microRNA target to at least one DNA nucleic acid, wherein said DNA nucleic acid contains a first region that is complementary to at least a portion of said microRNA target, and a second region that is not complementary to said microRNA target, wherein said second region of said nucleic acid forms a hairpin loop to form a half dumbbell structure when said DNA nucleic acid is hybridized to said microRNA, to generate a detection structure; and
b) detecting said detection structure.
