A research team affiliated with UNIST has unveiled an innovative, cost-effective biosensor capable of being washed and reused, paving the way for more accessible liquid biopsy diagnostics. This new ...

Abstract Reliable and cost-effective detection of single-stranded circulating cell-free DNA (ss-cfDNA) is crucial for liquid biopsies, offering a ...

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 ...

Oceanic ecosystems are increasingly threatened by global warming, which causes coral bleaching, species migration and, through the loss of habitats and biodiversity, food web disruptions on major ...

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.

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 ...

Iron is an essential trace element in biological cells. The concentration of the element and its so-called redox state—it can exist either in a doubly ionized state as iron (II) (Fe 2+) or a triply ...
