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 ...

(Nanowerk News) Electrochemical DNA biosensors hold significant promise for monitoring of various diseases. Overall, their detection applications are vast, from target DNA analytes such as bacterial ...

Previously, a similar approach to making biosensors was developed using a single DNA strand rather than a DNA origami structure. That earlier work was led by Kevin W. Plaxco (Ph.D. '94) of UC Santa ...

Double-strand breaks (DSBs) are a type of DNA damage where both strands of DNA break at the same location. They can adversely affect cell growth and functioning. Currently, DSBs are detected by ...

Cornell researchers have developed a powerful new biosensor that reveals, in unprecedented detail, how and where ...

The success of molecular medicine and biotechnology rests on the ability to measure molecular interactions in a variety of samples with speed, sensitivity, and accuracy. In an article published in the ...

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 ...

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 ...

Pictures of DNA often look very tidy—the strands of the double helix neatly wind around each other, making it seem like ...
