Caged molecules

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 cells, potentially leading to new methods of drug delivery.

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 synthetic DNA. These strands are designed so that they naturally assemble themselves into a tetrahedron (a pyramid with four triangular faces) around 7 nanometres tall. Science Daily
