Effect of Tween 80 on the Stability and Conformation of Telomeric G-Quadruplex DNA

G-quadruplex DNA is formed in telomer. It inhibits telomerase enzyme which is found active in more than 85 % of cancer cells. In this work, the effect of Tween 80 on telomeric G-quadruplex DNA, AGGG(TTAGGG)3 was studied using circular dichroism spectroscopic technique. The obtained results showed that using Tween 80 with telomeric quadruplex is safe up to less than 1.0 %.

Synthesis of Tween-Coated Silver Nanoparticles by a Plasma-Chemical Method: Catalytic and Antimicrobial Activities

Stable silver nanoparticles were rapidly synthesized by simple, eco-friendly atmospheric pressure plasma method using non-ionic Tween 80 (polyoxyethylene-(80)-sorbitan monooleate) as capping agent. Influences of Tween 80 concentration on the formation efficiency of silver nanoparticle, their average size and stability have been studied. The synthesized silver nanoparticles had significant antibacterial activity on two strains of Gram bacteria.
