The present study directly demonstrated that fine particles of ~30 nm in diameter were present inside each granule and occasionally formed straight chain arrangements. We considered that these fine particles correspond to the individual single cluster in the cluster model which has been proposed in previous studies on the starch granule structure 关键词: atomic force microscopy;biological techniques;macromolecules;molecular biophysics;atomic force microscopy;fine structure;rice starch granules;nanometre scale;physical destruction method;fine particles;straight chain arrangements;individual single cluster;cluster model;starch granule structure;30 nm
