The ability to detect, localize, quantity and monitor the expression of specific genes in living cells in real-time will offer unprecedented opportunities for advancement in molecular biology, disease pathophysiology, drug discovery, and medical diagnostics. However, current methods for quantifying gene expression employ either selective amplification as in PCR or saturation binding followed by removal of the excess probes as in microarrays and in situ hybridization to achieve specificity. Neither approach is applicable when detecting gene transcripts within living cells. Here we review the recent development in engineering nanostructured molecular probes for gene detection in vivo, describe probe design approaches and its structure-function relations, and discuss the critical issues and challenges in performing living cell gene detection with high specificity, sensitivity and signal-to-background ratio. The underlying biological and biochemical aspects are illustrated.
