Biomimetic molecules

In fact, such biomimetic molecules demonstrate the ability to tailor the growth of silica nanoparticles in a way that is very similar to diatom-extracted species. However, they demonstrate the same limitations in terms of morphological control of nanoparticle assembly. This is because the diatom shell architecture results not only from interactions of silica precursors with templating molecules but also benefits from a cell-driven molding of the vesicular compartment where silicification occurs [29]. Thus, it is very likely that diatom-like synthetic silica will only be achieved when such confinement/molding effects are taken into account in the design of biomimetic experiments [30].

Nafion is a membrane material of excellent physicochemical properties. Unfortnnately, its snrface properties promote protein adsorption, which eliminates it from many biomedical applications. To change it, the PP of tetraethylene glycol dimethyl ether (tetraglyme)/HEMA was deposited on the Nafion surface (Valdes et al. 2008). Nonfouling surfaces were obtained with a controllable number of hydroxyl groups to which biomimetic molecules could be linked. The problem of...

Biomimetic molecules copy the working mechanisms of molecules that are already found in our bodies. By synthesizing biomimetic molecules, effective and directed functions are achieved without side effects, since only the part of the molecule with the desired effect is copied, and the rest, which is generally responsible for undesired effects, is discarded. 

Currently there are a large number of biomimetic molecules with very different effects, some of them are cited in the following examples. 

Biomimetic molecules of two of the most abundant proteins in the extracellular matrix have been synthesized collagen and laminin. The slowing of the synthesis of these two proteins is one of the basic causes of the loss of skin firmness and the appearance of wrinkles. Working to assist synthesis of these proteins is fundamental to the smiggle against skin aging (Katayama et al, 1993).
