“…The potential for using lipid monolayer films as protein imprint matrices is evident in template-mediated crystal nucleation and biomineralization, where monolayers serve as fluid lattices that laterally restructure to favor epitaxial crystal nucleation and growth (105,106). This concept can be extended to impart recognition sites through adsorption-induced restructuring (patterning or templating) of fluid monolayers, as has been investigated using metal chelating lipid monolayers to target Histagged proteins (101).…”

Molecular imprinting is a generic technology that allows for the introduction of sites of specific molecular affinity into otherwise homogeneous polymeric matrices. Commonly this technique has been shown to be effective when targeting small molecules of molecular weight <1500, while extending the technique to larger molecules such as proteins has proven difficult. A number of key inherent problems in protein imprinting have been identified, including permanent entrapment, poor mass transfer, denaturation, and heterogeneity in binding pocket affinity, which have been addressed using a variety of approaches. This review focuses on protein imprinting in its various forms, ranging from conventional bulk techniques to novel thin film and monolayer surface imprinting approaches.

“…Prior to these studies, monolayers of N- (10,12-pentacosadiynoyl)glycine (6) were analyzed by BAM [86]. Calcite crystals were found to grow beneath a monolayer of 6 at low surface pressure (π = 0-5 mN/m), where the BAM image of the monolayer indicated smectic domains.…”

“…This is the basis for intermicellar CaCO 3 crystallization. 25 Although there are several studies regarding the effect of phospholipid molecules on the in vitro biomineralization process, [26][27][28][29][30][31]42 there has been no analysis of the effect of micelle spatial arrangement on the crystallization of CaCO 3 .…”

a Synthesis of inorganic particles using routes inspired by biomineralization is a goal of growing interest.Recently it was demonstrated that the size and geometry of crystallization sites are as important as the structure of charged templating surfaces to obtain particles with controlled features. Most biominerals are formed inside restricted, constrained or confined spaces where at least parts of the boundaries are cell membranes containing phospholipids. In this study, we used a gas diffusion method to determine the effect of different lecithin media on the crystallization of CaCO 3 and to evaluate the influence of the spatial arrangement of lecithin molecules on templating CaCO 3 crystal formation. By using inorganic synthesis, Raman spectroscopy, dynamic light scattering, electrochemical methods and scanning electron microscopy, we showed that the occurrence of surface-modified calcite crystals and diverse textured vaterite crystals reflects the geometry and spatial distribution of aqueous constrained spaces due to the lecithin assembly controlled by lecithin concentration in an ionized calcium chloride solution under a continuous CO 2 diffusion atmosphere. This research shows that by tailoring the assembly of lecithin molecules, as micelles or reversed micelles, it is possible to modulate the texture, polymorphism, size and shape of calcium carbonate crystals.
