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 ...

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 label-free nanopore platform uses programmable DNA circuits to build versatile molecular logic gates, forming a universal basis for scalable DNA computing and advanced biosensing applications.

The biosensor uses "capture probes" called aptamers, which are single strands of DNA that bind to virus proteins, flagging them. The team's big challenge was finding a way to get these aptamers to ...

Illustration of the high-sensitivity detection of trace amounts of cancer DNA in blood and its analysis using an AI-based method. Dr. Ho Sang Jung and his research team from the Advanced Bio and ...
