Researchers have successfully demonstrated a novel biosensor capable of detecting single-stranded DNA oligonucleotides with high specificity without needing external labels. This advancement paves the ...

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 ...

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 ...

A stronger current indicates that more of the molecule of interest is present. Previously, a similar approach to making biosensors was developed using a single DNA strand rather than a DNA origami ...

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 ...

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 ...

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 ...
