A selective magnetic adsorbent made from activated carbon and a magnetic filler enclosed within a cage of crosslinked PVA removes small nuisance molecules from food processing slurries, but leaves untouched macromolecules which have a high nutritional value (5). 

The size of these macrocycles and their cage-like structure renders them suitable to serve as host molecules or artificial receptors for small molecules, in addition to having possible biological activity. 

These are sodium and calcium aluminosilicates which have cage-like crystal lattice structures containing pores of various sizes, depending on their constitution. They can absorb small molecules, such as water, which can fit into the pores. The most commonly used types 3A, 4A, and 5A have pore sizes of approximately 3A, 4A, and 5A respectively, and they are available in bead or powder form. After activation at 250-320°C for a minimum of 3h they are probably the most powerful desiccants available.iC ) They can... 

Summarizing the field of ET using porous materials, it appears that zeolites act as active hosts and have advantages of manipulating reaction rates and product yields involving small molecules due to the close fits of the size of the molecule and cages. Mesoporous materials make it possible to examine the redox chemistry of larger molecules as compared with zeolites, while sol-gel materials form the primary hosts for enzyme-based redox reactions.
