A coarse-grained model of the DNA origami lilypad used in the study. The tails hanging down indicate where redox reporters are located. For scale, the diameter of the disk is approximately 80 nm.

Scientists have been studying ways to use synthetic DNA as a building block for smaller and faster devices. DNA has the advantage of being inherently "coded". Each DNA strand is formed of one of four ...

Fluorogenic DNA aptamers produce light only in the correct structural state, enabling programmable molecular logic, biosensing, DNA origami integrity reporting, and reusable mRNA detection through ...

An international research team has placed quantum light emitters onto silicon chips with roughly 90% success by using tiny triangles made of folded DNA, a result that exceeds the efficiency ceiling ...

According to the American Cancer Society, there will be an estimated 1,688,780 new cancer cases diagnosed and 600,920 cancer deaths in the U.S. in 2017. These numbers are stark and sobering, and worse ...

Previously, a similar approach to making biosensors was developed using a single DNA strand rather than a DNA origami structure. That earlier work was led by Kevin W. Plaxco (PhD '94) of UC Santa ...

Florian Praetorius and Prof. Hendrik Dietz of the Technical University of Munich (TUM) have developed a new method that can be used to construct custom hybrid structures using DNA and proteins. The ...
