A new microfluidic chip simplifies detecting and quantifying DNA by analyzing electrical impedance signals that vary based on DNA flowing across a biosensor inside the chip. The proof-of-concept ...
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 ...
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 ...
With aging populations on the rise, the need for better tools to diagnose and monitor Alzheimer's disease (AD), the most common cause of dementia, has ...
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 ...
CRISPR/Cas-based biosensors offer an opportunity to quantify neuroinflammation in Parkinson’s disease, advancing diagnostics ...
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.
