am·phi·path·ic

(am'fē-path'ik),
Denoting a molecule, such as comprises detergents or wetting agents, which contains groups with characteristically different properties, for example, both hydrophilic and hydrophobic properties.
Synonym(s): amphiphilic, amphiphobic
[amphi- + G. pathos, feeling]

amphipathic

Of a chemical structure having both hydrophobic and hydrophilic surfaces as in the case of the phospholipid molecules of the cell membrane. Some proteins have amphipathic regions.

amphipathic

a molecule containing both HYDROPHILIC and HYDROPHOBIC components, as in a phospholipid molecule. See FLUID-MOSAIC MODEL.

However, too long hydrophobic micro blocks of molecular chains easily turned the amphiphilic polymers from intermolecular association to intramolecular association, leading to a reduction of viscosity.
Two different amphiphilic copolymers, PEG-PCL and HA-g-PCL (Figure 1), were precious gifts provided by Dr.
It has been reported that GUV and SUV (small unilamellar vesicle) may break into smaller mixed micelles after long time incubation with amphiphilic copolymers [28, 29].
Thus, GO sheets are essentially amphiphilic. The hydration forces, together with the electrostatic repulsions between hydrated GO sheets, prevent the GO sheets from being fully compacted.
The self-assembly of amphiphilic molecules into fibrous structures has been studied extensively due to their high potential for many profitable applications.
Among various types of nanoordered carriers including inorganic and lipid particles, polymeric micelles and vesicles, which are prepared from self-assembling process of amphiphilic polymers, can encapsulate in general hydrophobic and hydrophilic compounds in the hydrophobic core and inner aqueous cavity regions, respectively [6-10].

The authors begin by discussing the history of the discovery of these compounds in the 1980s and move on to cover the use of amphiphilic, anionic and cationic AMPs to facilitate cell death in microbes.
Peptide-based block copolymers, biocompatible amphiphilic graft polyesters, polymers that can self-assemble into hierarchical nanostructures, lower critical solution temperature polymers, and supramolecular polymers containing cyclic oligomers are designed with the help of click chemistry.
A[sz]s are amphiphilic peptides with a hydrophilic N-terminal domain (residues 1 to 28) and a hydrophobic C-terminal (residues 29 to 40-42), the latter corresponding to a part of the transmembrane domain of APP.4 ?-Amyloid assembly into fibrils is initiated by a conformational transition from random coil to ?-sheet (hence the name ?-amyloid) and a nucleation-dependent aggregation process.4 A?
To evaluate the possibility of decreasing dirt pickup of coatings with the help of surface hardening nanoparticles, alkyd binders, acrylic binders and mixtures thereof we enriched with hydrophilic (Bindzil 40/220, average diameter 12 nm) or amphiphilic CC40, epoxy silane modified, average diameter 10 nm) silica nanoparticles.
