The work, a collaboration between physicists and molecular neuroscientists at Oxford, shows that artificial DNA cages that could be used to carry cargoes of drugs can enter living , potentially leading to new methods of .

A report of the research is published online in the journal ACS Nano.

The cages developed by the researchers are made from four short strands of . These strands are designed so that they naturally assemble themselves into a (a pyramid with four triangular faces) around 7 nanometres tall.

The Oxford researchers have previously shown that it is possible to assemble these cages around , so that the protein is trapped inside, and that DNA cages can be programmed to open when they encounter specific ‘trigger’ molecules that are found inside cells.
