DNA can signal the presence of or predisposition to a slew of diseases, including cancer. The ability to flag down these clues, known as biomarkers, allows medical professionals to make critical early ...

Article reviewed by Govind Kaigala, PhD at the University of British Columbia. Stay up to date on the latest science with Brush Up Summaries. In situ hybridization (ISH) is a molecular technique that ...

Part of the device is coated with single strands of DNA. When these "probes" encounter DNA biomarkers that have a corresponding, or complementary, genetic sequence, the two strands bind, sending a ...

The company's Check4 electrochemical detection platform can detect nucleic acid targets from blood or saliva samples in less than five minutes.

The challenges posed by the COVID-19 pandemic have stimulated innovation on several fronts. One is the development of low-cost methods of clinical diagnosis. Genosensors are a case in point. Based on ...

Mitochondrial DNA has long been treated as a workhorse record of cellular history, but new research suggests it also hides a subtle and previously overlooked form of damage. By uncovering this cryptic ...

Simulations have led to the fabrication of a polymer-DNA gel that could be used in tissue regeneration and robotics. Simulations have led to the fabrication of a polymer-DNA gel that could be used in ...

The DNA double helix is composed of two DNA molecules whose sequences are complementary to each other. The stability of the duplex can be fine-tuned in the lab by controlling the amount and location ...

MADISON — Using computer simulations, a team of University of Wisconsin-Madison researchers has identified some of the pathways through which single complementary strands of DNA interact and combine ...

In the rapidly widening arena of functional genomics, a few key players dominate the lab tools game. Perhaps the most prominent is the DNA microarray. This robust tool allows researchers to examine ...
