This study found that in Tris-HCl buffer, the resonance light scattering (RLS) intensity of the Eu(3+)-nicotinic acid system can be greatly enhanced by nucleic acids and the enhanced intensity is proportional to the concentration of nucleic acid in the range of 7 x 10(-8)-1 x 10(-5 ) g x mL(-1) for fsDNA, and its detection limit is 2 x 10(-8 ) g x mL(-1). Based on this, a new method for the det...

The concept of double stranded DNA forming triple helical complexes with a third strand of nucleic acids via so called Hoogsteenhydrogen bonds has been well established for the last 50 years. However, the topic reentered the big stage with recent publications pointing to an existence of these structures in vivo, highlighting their putative role in chromatin organization and transcriptional regu...

Information and communication technologies generate vast amounts of data that will far eclipse today’s data flows (Fig. 1). Memory materials must therefore be suitable for high-volume manufacturing. At the same time, they must have elevated information stability and limit the energy consumption and trailing environmental impacts that such flows will demand. Analysts estimate that global memory ...

The occurrence of nucleic acid cross contamination in the laboratory resulting in false positive results of diagnostic samples is seriously problematic. Despite precautions to minimize or even avoid nucleic acid cross contaminations, it may appear anyway. Until now, no standardized strategy is available to evaluate the efficacy of commercially offered decontamination reagents. Therefore, a prot...
