Johns Hopkins engineers have created a new optical tool that could improve cancer imaging. Their approach, called SPECTRA, uses tiny nanoprobes that light up when they attach to aggressive cancer ...

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.

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 ...

Chemists present two studies that open up new possibilities for biotechnological applications. LMU chemists present two studies that open up new possibilities for biotechnological applications. In the ...

One of the challenges of fighting pancreatic cancer is finding ways to penetrate the organ's dense tissue to define the margins between malignant and normal tissue. A new study uses DNA origami ...

To assemble these minuscule structures, researchers first create a scaffold: a long piece of single-stranded DNA with a carefully designed sequence of bases. Then they add hundreds of shorter DNA ...

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 ...
