Superparamagnetic Magnetite Colloidal Nanocrystal Clusters

摘要

Recent advances in colloidal synthesis have enabled the preparation of high-quality nanocrystals with controlled size and shape.The focus of synthetic efforts appears to be shifting to creation of secondary structures of nanocrystals,either by self-assembly or through direct solution growth.This trend is evidenced by a number of interesting works published in the past two years.
