Abstract
Magnetic nanocrystal clusters exhibit unique properties that differ from the constituent nanocrystals due to the intracluster interactions. This Review summarizes the recent advances in the synthesis and application of magnetic nanocrystal clusters. Specifically, we describe the formation mechanism of the clusters, discuss the strategies to control the dimensions of the clusters and primary nanocrystals, and showcase the applications of clusters in magnetic hyperthermia cancer therapy, magnetic resonance imaging, drug delivery, wastewater treatment, and the formation of photonic crystals. The opportunities and challenges in improving magnetic nanocrystal clusters for different applications are also discussed.
