In the beginning of 20th century, the first study to focus on self-assembly nanoparticles at interfacings was done. Pickering Emulsion is an example of a phenomenon where solid particles can spontaneously migrate onto fluid interfaces forming monolayers or multiple layers. Food, cosmetics and the pharmaceutical industry are all interested in using interfaces to aid the directed assembly. Reduced interfacial force is key to liquid interface-induced mixing. It is possible to adjust the sizes and chemical characteristics of the particles as well the properties of the binding ligands. Use for your pickering lotion Emulsions are not thermodynamically stable due to the high oil/water interaction area. It is necessary to add an emulsifier as a third substance in order for the system to be stable. Presently, Pickering is known to have a stabilizer mechanism. This involves the adsorption on oil/water interface of solid particles and the formation of single or multiple layers of film that will help stabilize the emulsion.

Nanoparticles – Structure Template

A key component of nanotechnology are nanoparticles. Especially after Pickering was discovered, more research is being done on the self-assembly behavior for nanoparticle interface. Recently, there has been more research into the use of nanoparticles in preparation of capsules. Enveloping method and solvent evaporation methods are the most commonly used for preparation of nanometer- or micron-size capsules.

Nanoparticle interface self-assembly

Homogeneous nanoparticles

The application and development of nano-particles (CdSe/Au, etc.) is a key factor in the success of this technology. New nanomaterials made of nanoparticle assemblies have been a topic of great concern due to surface functionalization technology.

Interface self-assembly by Janus particles

De Gennes was the first to propose the Janus particle. However, Janus’ potential application in various areas, including drug carriers, electronic devices as well as optics and biosensing, has been intensively researched. Janus is the original two gods in Rome. Janus Nanoparticles consist of particles with different chemical surfaces and polarities. By appropriate modification, the hydrophilic-lipophilic balance of the Janus particle surface can be controlled to adjust its distribution at the oil-water interface.

Interface assembly of nanorods

Recently, the anisotropic nanorods gained more and greater attention. Nanoparticle synthesizer technology now allows the creation of many different types of inorganic, nanometer-rods, like CdSe, CdS, Co, Au, CdSe, CdS, Co, Au, among others. The performance of nanorod composites in optical and electromagnetic field applications has been demonstrated by studies. Interfacial interactions of nanorods show properties distinct from those found in isotropic nanoparticles because they have different particle sizes, shapes and surfaces.

Interface assembly of biological particles

This modification and the monodispersity for size and shape of bionanoparticle surface protein provide useful value in particle formation. By interfacial self assemblage of bio­nanoparticles, biomaterials can also be made. Recent years have seen it become an increasingly popular area.
