Ultrasensitive DNA quantification by light scattering

Traces of biomolecules such as DNA can be detected with a new "dynamic" technique based on the observation of association and dissociation events of gold nanoparticles. If the desired DNA sequence is present, it can reversibly ...

DNA microcapsules: Scaling up the future of data storage

Storing data in DNA sounds like science fiction, yet it lies in the near future. Professor Tom de Greef expects the first DNA data center to be up and running within five to ten years. Data won't be stored as zeros and ones ...

Microelectronics: Automating cancer detection

Microelectronic engineers in Singapore have developed and tested sensor technology that can detect and measure a chemical signature of bladder cancer. The light-based sensor could eventually be used for the early diagnosis ...

DNA catalysts do the work of protein enzymes

(Phys.org) —Illinois chemists have used DNA to do a protein's job, creating opportunities for DNA to find work in more areas of biology, chemistry and medicine than ever before.

Researchers develop new sensor for methylated DNA

Collaborators from Mayo-Illinois Alliance for Technology Based Healthcare have developed a new, single molecule test for detecting methylated DNA. Methylation—the addition of a methyl group of molecules to a DNA strand—is ...

Scientists program proteins to pair exactly

Proteins have now been designed in the lab to zip together in much the same way that DNA molecules zip up to form a double helix. The technique, whose development was led by University of Washington School of Medicine scientists, ...

Crab disease poses threat to shellfish stocks

Shore crabs carry parasites that pose a major threat to shellfish stocks. In a new study, Swansea University researchers have used several different detection methods, including taking DNA from seawater, to build up the first ...
