“…Highly fluorescent patches are also observed, likely due to local probe aggregation. Dark domains, likely due to SM molecules in a liquid condensed phase, are different from those already reported for SM monolayers obtained by compression, at the same surface pressure [22,23]. This difference is probably due to the mode of preparation of the monolayer.…”

“…This difference is probably due to the mode of preparation of the monolayer. Indeed, monolayers studied in this work are directly spread at a relatively high surface pressure (30 mN/m) and are not compressed, contrary to monolayers described in other studies [22,23]. After injection of β-CD, dark domains disappear progressively as shown in Fig.…”

“…In these systems, lipids are either tethered to the substrate [18][19][20][21][22], or stabilized on it due to strong adhesive interactions [19,[23][24][25][26]. In this regard, it can be deemed most efficient to employ the Langmuir-Blodgett (LB) and Langmuir-Schaeffer (LS) methods, which make possible to form and to study lipid bilayers, stable if they are kept in contact with an aqueous phase, with various inclusions, on virtually any solid hydrophilic supports [19,20,[27][28][29][30][31][32][33][34][35].…”

Abstract⎯In this work, we study the interaction of a well-known photosensitizer, MePha, with models of biological membrane (Langmuir monolayers and Langmuir-Schaeffer planar bilayers) based on one of the most important natural lipid, POPC, for the subsequent investigation of photodestruction processes in a context of photodynamic therapy treatment. Changes of macroscopic properties and morphology of POPC/MePha model membranes upon irradiation by visible light are recorded by means of contact angle measurements and atomic force microscopy, demonstrating clearly the possibility to use these methods for the study of photodestruction of artificial lipid membranes on solid substrates, but also for a comparative study of the efficiency of novel photosensitizers.

“…Evidence is growing that biological membranes contain lipid microdomains or "rafts" that may be involved in processes such as cellular signaling and protein trafficking [22,36,41,53,55,63]. An AFM operates by measuring attractive or repulsive forces between a tip and the sample [23].…”

-This paper presents a personal view on the potential applications of the milk fat globule membrane as an ingredient in the processed foods area. Several factors are of importance for this dissertation: the biological origin of the membrane, the voluminous literature on its individual components and their relationship with health and wellness, the biological role of milk in nutrition to mammals and the innovation on scientific tools being applied in many fields of chemistry and biology. We hope to give a glimpse of the reasons on why it is a good idea to use more efficiently the components of the milk fat globule membrane. In addition we consider current advances in the fractionation of milk components to propose how this ingredient can be produced. However, we leave the timing question, when?, open for discussion in the different scientific and technological fields. milk fat globule membrane (MFGM) / isolation / analytical tools / biological activitiesRésumé -Application de la membrane du globule gras du lait comme ingrédient : perspectives actuelles et futures. Cet article présente nos vues personnelles sur les applications potentielles de la membrane du globule gras du lait comme ingrédient dans le domaine de la transformation alimentaire. Notre réflexion s'articule sur les éléments suivants : l'origine biologique de la membrane du globule gras, la vaste littérature couvrant ses divers composants et leur impact sur la santé et le bien-être, le rôle nutritionnel du lait chez les mammifères et le recours à des outils analytiques novateurs associés aux domaines de la chimie et de la biologie. Nous espérons que ce survol permettra de convaincre le lecteur de l'importance d'optimiser l'utilisation des divers composants de la membrane du globule gras du lait. Cet article propose également un aperçu des plus récents dé-veloppements techniques qui permettront de fractionner et de produire commercialement ces composants. Nul doute que la réalisation de ces défis continuera de stimuler les milieux scientifiques et technologiques.
