Amphipathic design dictates self-assembly, cytotoxicity and cell uptake of arginine-rich surfactant-like peptides

Amphiphilicity is the most critical parameter in the self-assembly of surfactant-like peptides, regulating the way by which hydrophobic attraction holds peptides together.

Physical Origins of Surface Forces

The energies and forces between contacting surfaces originate from the interaction forces between atoms and molecules. This chapter discusses how these atomic level forces lead to various types of force–separation relations as two surfaces are brought into contact. This chapter covers the interactions between atoms (repulsive atomic potentials and van der Waals interactions), the interactions within liquid and aqueous media (solvation forces, electrostatic double layer, hydration repulsion, hydrophobic attraction), and electrostatic interactions from contact electrification. Due to their ubiquitous effect on adhesion, van der Waals interactions are discussed at length, including examples for calculating adhesive forces in different geometries using Hamaker constants.

Forces between zinc sulphide surfaces; amplification of the hydrophobic attraction by surface charge

Surface force measurements reveal that a small increase in surface charge enhance the long range hydrophobic attraction.

Cobalt(iii) acetylacetonate initiated RAFT polymerization of acrylonitrile and its application in removal of methyl orange after electrospinning

Electrostatic repulsion (ER) played a key role at low solution pH. Enhancement of hydrophobic attraction (HA) and hydrogen bond (HB) increased the adsorption capacity at higher solution pH.
