The development of methods for non-invasive, real-time imaging of gene expression would provide powerful tools for biomedical research and medical diagnostics. A broadly applicable strategy for achieving this goal is the use of complementary oligonucleotide probes for recognition of mRNA. The major challenge for molecular imaging is the development of specific and efficient transducers for signaling probe-target interaction. This review summarizes the strengths and limitations of reported molecular approaches for imaging of mRNA expression and discusses the challenges to development of in vivo methods.
