The sensor uses a DNA origami scaffold, which consists of two arms connected by a molecular “hinge.” Each arm is tagged with a fluorescent dye, and the distance between the tags is recorded by means ...

DNA origami suggests route to reusable, multifunctional biosensors Using an approach called DNA origami, scientists have developed a technique that could lead to cheaper, reusable biomarker sensors ...

Inspired by biological systems, materials scientists have long sought to harness self-assembly to build nanomaterials. The challenge: the process seemed random and notoriously difficult to predict.

Over the past decades, a growing number of robotics teams have started developing modular robots inspired by the ancient paper-folding art of origami. More recently, some of these teams started ...

Dr. Ho Sang Jung and his research team from the Advanced Bio and Healthcare Materials Research Division at the Korea Institute of Materials Science (KIMS) have developed an optical biosensor capable ...

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 ...

Fusobacterium nucleatum, a bacterium linked to colorectal cancer, possesses a specific gene called fadA that serves as an early diagnostic biomarker. The CRISPR/Cas12a system has demonstrated marked ...

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.
