Chemists use modified DNA nucleotides to create new materials

DNA evolved to store genetic information, but in principle this special, chain-like molecule can also be adapted to make new materials. Chemists at The Scripps Research Institute (TSRI) have now published an important demonstration ...

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 ...

Refined DNA tool tracks native and invasive fish

Rather than conduct an aquatic roll call with nets to know which fish reside in a particular body of water, scientists can now use DNA fragments suspended in water to catalog invasive or native species.

Identifying species from a single caviar egg

A new tool enables identification of high-end caviar from Beluga sturgeons by analyzing DNA from a single caviar, a development that helps ensure the fair international trade of caviar and contributes to conservation of the ...

Researchers develop eco-friendly, 4-in-1 catalyst

Brown University researchers have developed a new composite catalyst that can perform four separate chemical reactions in sequential order and in one container to produce compounds useful in making a wide range of pharmaceutical ...

A new approach to amplifying DNA

Analyzing DNA is useful for a number of vital applications. This includes diagnosis and monitoring of diseases, identification of criminals, and studying the function of a targeted segment of DNA. However, methods used for ...
