Targeted delivery of intracellularly active diagnostics and therapeutics in vivo is a major challenge in cancer nanomedicine. A nanocarrier should possess long circulation time yet be small and stable enough to freely navigate through interstitial space to deliver its cargo to targeted cells. Herein, it is shown that by adding targeting ligands to(More)
We report a new class of photodynamic molecular beacon (PMB) with tumor specific mRNA-triggered control of singlet oxygen ((1)O(2)) production. The beacon contains a single-stranded oligonucleotide linker that forms a stem-loop structure (hairpin) in which the sequence is an antisense oligonucleotide (AS-ON) complementary to a target mRNA. The stem is(More)
