Monodisperse silver rings with nanometer-scale diameters (see Figure) are produced due to the ability of DNA organize into toroidal condensates well-defined shapes and sizes upon its interaction multications. Silver ions can bind residual negative surface charge condensed DNA, then reduced metal yield toroids coated a thin shell.
