Polyethyleneimines (PEIs) are extensively researched as non-viral vectors for gene and medication delivery because of their capacity to condense nucleic acids into nanoparticles known as polyplexes. 1 ...

It's a common storytelling trope: the stubborn foe who is eventually revealed to be a much-needed friend. Biology has its own ...

Researchers have identified a form of molecular motion that has not previously been observed. When what are known as "guest molecules"—molecules that are accommodated within a host molecule—penetrate ...

The structure of semi-crystalline polymers largely depends on how strongly their molecular chains are entangled. Following numerous experiments, researchers developed a new model to predict the ...

Biology lectures teach students that when a cell’s replication machinery comes together, DNA polymerase takes off down the double-helix like a car on a highway ...

Inside cells, DNA twists and coils itself into a variety of different secondary structures—including i-motifs (iMs) and G-quadruplexes (G4s)—that influence gene expression. Some drugs target these ...

CPL-active polymeric materials are superior in terms of scalability, flexibility, 3D stacking ability, and film-forming properties. CPL can be produced directly using chiral luminescent materials, ...

Using an inexpensive electrode coated with DNA, MIT researchers have designed disposable diagnostics that could be adapted to detect a variety of diseases, including cancer or infectious diseases such ...
