Nanoemulsions have attracted a significant interest in cell culture technology. Nanoemulsions systems are generally based on natural triacylglycerols: phospholipids. Nanoemulsion systems can also be used as antimicrobial agents. For example, there is a growing interest in the use of essential oils as antimicrobial agents in food products. However, their low solubility in aqueous phases, their reactivity, and their volatility remain technological limitations.
Template technology has the advantage to control the architecture morphology, particle size, and structure of the materials synthesized on the nanoscale during the preparation. Therefore, materials with specific properties optical, magnetic, elastic, or chemical can be easily designed. A large number of nanoparticle preparation methods are based on nanoemulsion templates, notably for drug delivery applications.
This technique has the advantage to be readily adaptable to the target drug and to the administration route by choosing suitable nanoemulsion formulation method and surfactant Anton et al. Template technology using nanoemulsions is also applied to the preparation of mesoporous materials, which find applications in many industrial fields e. Their traditional method of production involves the use of a hard template, mesoporous silica for example. However, there is more and more research published on the use of soft templates surfactants, polymer.
The advantages are a good repeatability and controllability, a simplified process and no difficulty to remove the template Xie et al. On this topic, a review focused on the use of lipopeptides as candidates for creating supermolecular gels as templates for the synthesis of nano and micromaterials Delbecq, Sustainable chemistry continues progressively to gain attention in the society with the interest in preserving resources, in limiting its impact on health and environment, and in developing new processes.
Today, there is a strong demand for the replacement of conventional surfactants with more environmentally friendly and nontoxic compounds. The challenge is to use renewable feedstock, such as sugar, starch, proteins, or oils, and to develop green technologies cleaner solvents, biotechnological processes These new green surfactants would be a solution for the everyday uses but also for highly specialized applications, such as protein crystallization or nanotechnologies.

Abstract Surfactants find applications in almost every chemical industry, such as household and industrial cleaning, paper, inks, agrochemicals, and personal care or pharmaceuticals. Figure 1 Open in figure viewer PowerPoint. Different molecular architectures of surfactants.
Adapted from Chevalier, Surfactants from Renewable Resources Surfactants were originally produced from renewable resources like fats and oils. Rhamnolipids Thanks to their useful emulsifying, solubilizing, foaming, and antimicrobial properties, RL have been the subject of great interest. Figure 2 Open in figure viewer PowerPoint. Figure 3 Open in figure viewer PowerPoint. Surfactants based on a Natural Polar Head Group Various types of surfactants from sugars or polyols as polar head groups have been developed over the years.

Surfactants based on a Natural Hydrophobic Tail Fatty Acid as a Hydrophobic Tail The larger part of renewable hydrophobic tails derives from fatty acids of either plant or animal tallow triacylglycerols Svensson, Scheme 1 Open in figure viewer PowerPoint. Nitrogen Derivatives of Fatty Acids Fatty acids are precursors for the synthesis of many nitrogen derivatives Franklin, ; Franklin et al. Sterol as a Hydrophobic Tail Sterols belong to the triterpen family and have a tetracyclic structure with a secondary hydroxyl group on the first ring and a side chain on the fourth ring.

Surfactants in Nanotechnology Nanotechnology has a significant place in many industries, from telecommunication and electronics to pharmaceuticals. Drug Delivery Applications Nanoemulsions can also be applied for drug delivery due to their specific properties: thermodynamic stability, increased surface area, easy preparation, high bioavailability, and optical transparency.
Biotechnology Applications Nanoemulsions have attracted a significant interest in cell culture technology.
