Study of ionic surfactants interactions with carboxylated single-walled carbon nanotubes by using ion-selective electrodes
(Elsevier, 2016)
Potentiometric measurements based on the use of ion-selective electrodes have been used to study the interaction (adsorption) of anionic and cationic surfactants with functionalized single-walled carbon nanotubes (SWCNT-COOH). ...

Multivalent Calixarene-Based Liposomes as Platforms for Gene and Drug Delivery
(MDPI, 2021-08)
The formation of calixarene-based liposomes was investigated, and the characterization of these nanostructures was carried out using several techniques. Four amphiphilic calixarenes were used. The length of the hydrophobic ...

Influence of the surfactant degree of oligomerization on the formation of cyclodextrin: surfactant inclusion complexes
(Elsevier, 2020)
Supramolecular complexation is an attractive strategy to modulate the performance of surfactants, e.g., by host-guest interactions. Here, we investigate the interaction of single-chained, di-, tri-, and tetrameric cationic ...

Host-guest interactions between cyclodextrins and surfactants with functional groups at the end of the hydrophobic tail
(Elsevier, 2017)
The aim of this work was to investigate the influence of the incorporation of substituents at the end of the hydrophobic tail on the binding of cationic surfactants to α-, β-, and -cyclodextrins. The equilibrium binding ...
