Tumor microenvironment-triggered fabrication of gold

Herein, we developed an alpha-cyclodextrin (α-CD)-based gold/DNA nanomachine for tumor-selective diagnosis and therapy. The α-CDs were capped at the ends of DNA, and their release was triggered by the low pH of the tumor microenvironment, which further resulted in DNA self-assembly through complementary base pairing.
