Four particle sizes of the nano-Se, ranging from 45-220 nm in diameter, were examined. All of them, unlike their bulk material, show clear capabilities of inhibition and a trend dependent on the particles size. The inhbition be comes more potent as the particle size in creases. It indicates that pursuing the reduction of colloidal sizes into nanoscale is not favoured in this biological system. |
