DNA Star Ultra-Sensitive Test

Authors: George Rajna

By folding snippets of DNA into the shape of a five-pointed star using structural DNA nanotechnology, researchers have created a trap that captures Dengue virus as it floats in the bloodstream. [23] A team led by Cornell University physics professors Itai Cohen and Paul McEuen is using the binding power of magnets to design self-assembling systems that potentially can be created in nanoscale form. [22] Histones are proteins that regulate the unwinding of DNA in the cell nucleus and the expression of genes based on chemical modifications or "marks" that are placed on their tails. [21]
