Mimetic material

Standards are needed to find M " 1 monolayer of mimetic material 20—40 nm... 

These ordered array materials find interest not only in catalysis, but in several other applications, from optical materials, sensors, low-k materials, ionic conductors, photonic crystals, and bio-mimetic materials.Flowever, with respect to these applications, catalysis requires additional specific characteristics, such as the presence of a thermally stable nanostructure, the minimization of grain boundaries where side reactions may occur, and the presence of a porous structure which guarantees a high surface area coupled to low heat and mass transfer limitations. An ordered assembly of ID nanostructures for oxide materials could, in principle, meet these different requirements. 

With the addition of a catalytic centre, an imprinted recognition site can be transformed into an enzyme mimetic material offering substrate selective catalysis. Over the past decade a few research groups have studied catalytic effects of imprinted metal oxides in esterification reactions. In this section a brief overview will be given on their efforts to understand the catalytic selectivity and structure of the active site. For additional reading an excellent review can be found by Davis et al. [46]. 

The complexity in CAPE applications also results from new opportunities offered by proteomics, materials science (self-assembled materials, nanomaterials, bio-mimetic materials), and pharmaceutical science (combinatorial design of molecules, drug delivery systems).
