A typical amphiphilic flexible surfactant can form aggregates through a self-assembly process that results of specific interactions between the molecules of the amphiphilic mesogen and those of the non-mesogenic solvent. In aqueous media, the driving force of the aggregation is the "hydrophobic effect". The aggregates formed by amphiphilic ...
In chemistry, an amphiphile (from Greek αμφις (amphis) 'both' and φιλíα 'love, friendship'), or amphipath, is a chemical compound possessing both hydrophilic (water-loving, polar) and lipophilic (fat-loving, nonpolar) properties. [1] Such a compound is called amphiphilic or amphipathic.
The characterization of mechanical properties in polymers typically refers to a measure of the strength, elasticity, viscoelasticity, and anisotropy of a polymeric material. The mechanical properties of a polymer are strongly dependent upon the Van der Waals interactions of the polymer chains, and the ability of the chains to elongate and align ...
Peptide amphiphiles were developed in the 1990s. They were first described by the group of Matthew Tirrell in 1995. [5] [6] These first reported PA molecules were composed of two domains: one of lipophilic character and another of hydrophilic properties, which allowed self-assembly into sphere-like supramolecular structures as a result of the association of the lipophilic domains away from the ...
[3] [4] [5] Amphipols can be used to fold denatured membrane proteins to their native form [6] [7] and have proven particularly precious in the field of single-particle electron cryo-microscopy (cryo-EM; see e.g. [8] [9]).The properties and uses of amphipols and other non-conventional surfactants are the subject of a book by Jean-Luc Popot.

Polymer chemistry is a sub-discipline of chemistry that focuses on the structures, chemical synthesis, and chemical and physical properties of polymers and macromolecules. The principles and methods used within polymer chemistry are also applicable through a wide range of other chemistry sub-disciplines like organic chemistry , analytical ...
This process affects mechanical properties of the polymers and decreases their volume because of a more compact packing of aligned polymer chains. [4] [7] The chains interact via various types of the van der Waals forces. The interaction strength depends on the distance between the parallel chain segments, and it determines the mechanical and ...
Copolymers are highly desired due to the increased flexibility of properties a polymer can have compared to their homopolymer counterparts. The synthetic techniques used range from ROMP to generic anionic or cationic living polymerizations. [4] [5] Copolymers, due to their unique tunability of properties, can have a wide range of applications.
