The size and distribution of microvoids in Bombyx mori silk were examined by transmission electron microscopy of silver sulphide 'stained' filaments. Silver sulphide deposited in voids and accessible regions of molecular structure appears as dense particles in thin transverse and longitudinal sections of silk filaments. Small particles (about 8 nm or less in diameter) occur around or adjacent to the periphery of the filaments. Larger particles (around 10-15 nm in diameter) occur in the form of dendritic arrays in the core region of the filaments. The leading edges of the dendritic arrays are oriented towards the fibre periphery. The particles (microvoids) appear to be either spherical or rod-like in shape and are aligned parallel to the long axis of the filament. A skin/core structure is proposed.
