▎ 摘 要
Micron-sized hollow capsules composed of graphene oxide and small molecule cross-linker are prepared and isolated. These capsules are thoroughly characterized using various spectroscopic and microscopic techniques. The cross-linked and non-cross-linked microcapsules show distinct release profiles from each other. Moreover, the microcapsules can be loaded with gold nanoparticles, suggesting these structures are useful in encapsulation technologies. (C) 2016 Elsevier Ltd. All rights reserved.
