First-of-its-kind chemical oscillator offers new level of molecular control

Added: 15.12.2017 17:55 | 2 views | 0 comments

Researchers successfully constructed a first-of-its-kind chemical oscillator that uses DNA components. DNA molecules that follow specific instructions could offer more precise molecular control of synthetic chemical systems, a discovery that opens the door for engineers to create molecular machines with new and complex behaviors.

Programmable drug delivery platform combats diseased cells at genetic level

Added: 15.12.2017 3:41 | 7 views | 0 comments

A research team has developed a unique linker technology to connect a synthetic drug delivery vehicle referred to as a nucleic acid nanocapsule (NAN) with a new peptide cross-linker approach. The NAN enables both a small molecule drug and a nucleic acid -- RNA or DNA -- to be delivered to a cell. This combination generates a nanocapsule capable of shepherding genetic or pharmaceutical molecules to a target on or within a cell.

Spaghetti-like, DNA 'noodle origami' the new shape of things to come for nanotechnology

Added: 15.12.2017 3:40 | 8 views | 0 comments

Scientists have invented a major new advance in DNA nanotechnology. Dubbed 'single-stranded origami,' their new strategy uses one long, thin noodle-like strand of DNA, or its chemical cousin RNA, that can self-fold -- without even a single knot -- into the largest, most complex structures to date. The strands forming these structures can be made inside living cells, opening up the potential for nanomedicine.

DNA: Supercoiling pushes molecular handcuffs along chromatin fibres

Added: 14.12.2017 23:54 | 7 views | 0 comments

As it squeezes down the chromatin fiber, the cohesin protein complex extrudes a growing loop of DNA -- a bit like the quick-lacing system of trail-running shoes. But what is powering the movement of the protein? A team of scientists has found that the driving force could be the supercoiling of upstream DNA. Their research is thereby adding a key piece to the puzzle of gene expression regulation.
