DOX-loaded silica nanostructures exhibiting superb drug release behavior, which is controlled by varying the pH was reported by Tan et al. (2011). Porous hollow silica nanoparticles (HSNS) have been successfully fabricated by a novel combination of stabilizing condensation and dynamic self-assembly. Further, encapsulation of organic molecules into HSNS and their controlled release were... 

The encapsulations of organic molecules, like 9,10-dichloro-anthracene, jS-carotene, and coronene was found to be effective to increase the reversible storage capacity. Especially for the SWNT with coronene, the reversible capacity is 736 mAh/g, which is about 2.5 times greater than that of original empty tube. This is due to the steric hindrance of the organic molecules in the tube. The electrol3 e molecules and solvated Li ions cannot enter the tube. 

In small pore zeolites with cage structure, e. g., faujasites, dye molecules encapsulated by in situ synthesis or crystallization inclusion are stable against extraction.1 2 However, these methods fail for MCM-41 due to the channel structure and the wider pore diameter (3 nm) of the host material. Covalent bonding of guests is necessary to obtain diffusion stability. Therefore, anchoring of organic molecules with catalytic functions into MCM-41 by covalent bonding was recently reported by Brunei et al.3... 

Since the CDPs could capture the organic molecules and complex the metal ions from the liquids, they are used in the field of environmental monitoring and wastewater treatment. If the pesticide is encapsulated in the insoluble polymers, it will not be washed out by rain.
