These types of molecules are termed "bola-amphiphiles" commonly known as "bolaforms". Surface activity of these molecules depends on both the hydrocarbon chain length and the nature of head group(s). Amphiphiles with longer hydrocarbon chains are found to be more surface-active compared to those...
Self-assembly of surfactants: An overview on general aspects of amphiphiles SampadGhosh, ...NabakumarPramanik, inBiophysical Chemistry, 2020 3Biocompatible surfactants Anionic surfactantsare widely used for cosmetic and toiletry products such as shower gels and hair shampoos. Today, the properties deman...
intra-operatory control of sonication [21], and early assessment of radiological changes in tissue [22]. Near real-time MR temperature monitoring based on the proton frequency resonance shift (PRFS) enables feedback for the automated control of the ultrasound beam to achieve precise...
An amphiphilic substance exhibits a double affinity, which can be defined from the physico-chemical point of view as a polar-apolar division. On the one hand, an amphiphiles has a polar group made up of heteroatoms such as Oxygen (O), Sulphur (S), Phosphorus (P), or Nitrogen (N), inc...
2.1Nonionic Amphiphiles According togreen chemistrycriteria much attention is paid to surfactants with low toxicity and low aggregation threshold. These trends are taken into account in our recent researches directed toward construction of self-assembling nanosystems capable of incorporating nonpolar bioactive...
All amphiphiles can undergo entropy-driven self-assembly processes in water, which comprise a double phase separation: that of hydrophobes from water and the intramolecular one ofhydrophilesfrom hydrophobes. When water is added slowly to a solution of amphiphile in a water-soluble organic solvent...

Microbial bio-based amphiphiles (biosurfactants): General aspects on critical micelle concentration, surface tension, and phase behavior NikiBaccile,AlexandrePoirier, inBiosurfactants, 2023 1Introduction Surfactantsare a class of chemicals applied in a vast array of applications and markets, reaching product...
Niosomesare composed of non-ionicamphiphiles(surfactants) and are similar in function to the liposomes[150,171–173]. Several studies have documented the superiority of niosomes in enhancing permeation of drugs across the stratum corneum[171,174,175]. Recently, Paolino et al.[176]have shown that...
Therefore, amphiphilic protein conjugates with rational composition may behave as novel amphiphiles for the design of supramolecular protein vesicles because proteins also show similar profiles with polymer structures. The key point for amphiphilic construction of 2D protein vesicles is which driving force ...
