DNA origami sounds like science fiction, but for HIV vaccine researchers it is becoming a practical design tool. By folding strands of DNA into tiny three-dimensional scaffolds, scientists can arrange ...

A new vaccine design uses folded DNA to steer the immune system toward producing the rare immune cells needed to make protective antibodies against HIV.

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.

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 ...

One of the biggest hurdles in developing an HIV vaccine is coaxing the body to produce the right kind of immune cells and ...

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 ...

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 ...

A dissertation study at the University of Jyväskylä (Finland) developed two-dimensional fishnet-like structures from DNA origami for silicon surfaces and investigated how different conditions affect ...

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 ...

LMU chemists present two studies that open up new possibilities for biotechnological applications. In the world of nanotechnology, the development of dynamic systems that respond to molecular signals ...
