Selective assembly of DNA origami bridging over a trenched Si substrate

This entry was posted in DNANanotech Research on

We demonstrated for the first time the versatility of the integration method of DNA origami on MEMS by selectively assembling it to form a bridge over a trenched silicon. A DNA origami (30 x 150 nm) was fixed to bridge the trench (100 nm width) utilizing the hybridization between DNA on the DNA origami and selectively immobilized complementary DNA-pattern at the edges of trench. This opens a way to integrate the nanomaterial components on a structured device such as MEMS by using DNA origami.
