Interação de moléculas sintéticas anfifílicas catiônicas com modelos miméticos de biomembranas
(Universidade Federal de São Paulo (UNIFESP), 2018-09-27)
Bacterial infections represent a serious health problem, aggravated by the resistance of
these microorganisms to conventional antibiotic agents. Therefore, alternative treatments,
such as those based on antimicrobial ...
Fatty acid conjugates of Toluidine Blue O as Amphiphilic Photosensitizers: Synthesis, solubility, photophysics and photochemical properties(dagger)
(Wiley, 2020)
Toluidine blue O (TBO) is a water-soluble photosensitizer that has been used in photodynamic antimicrobial and anticancer treatments, but suffers from limited solubility in hydrophobic media. In an effort to incrementally ...
Spontaneous catanionic vesicles formed by the interaction between an anionic β-cyclodextrins derivative and a cationic surfactant
(Royal Society of Chemistry, 2018-03)
The present work shows the synthesis of a new type of catanionic surfactant, ModCD14-BHD, which involves an anionic amphiphilic cyclodextrin and the cationic benzyl-n-hexadecyldimethylammonium (BHD). It is obtained from ...
L-DOPA modulates the kinetics but not the thermodynamic equilibrium of TTA+ amphiphiles forming lyotropic nematic liquid crystals
(2020-04-17)
Lyotropic liquid crystals (LLCs) are mixtures of amphiphile molecules usually studied as mimetic of biological membrane. The equilibrium dynamics of tetradecyltrimethyl ammonium cation (TTA+) molecules forming nematic LLCs ...

Ação de aditivos moleculares em dispersões de vesículas e filmes de Langmuir de moléculas anfifílicas
(Universidade Estadual Paulista (Unesp), 2019-10-29)
A utilização de carreadores não virais de fármacos, de baixo custo comercial, requer estudo das propriedades físico-químicas e caracterização desses carreadores. Uma opção para carreador não viral são vesículas de lipídios ...
About the difference in the quadrupole splitting of water between cationic and anionic nematic lyotropic liquid crystals. H-2-NMR and molecular dynamics study
(SOCIEDAD CHILENA DE QUIMICA, 2004-09)
Deuterium quadrupole splittings, of deuterated water, Deltav, in anionic discotic nematic lyomesophases are always much larger than in cationic mesophases. To explore the possible origins of this difference, Deltav and T-1 ...
Raman spectra of acetonitrile in imidazolium ionic liquids
(WILEY-BLACKWELL, 2010)
Raman spectra of dilute solutions of acetonitrile in ionic liquids reveal the characteristic features of ionic liquids` polarity. This is accomplished by investigating the Raman bandshape of the nu (CN) band, corresponding ...
The impact that catatonic surfactants have on the soft matter world
(Anales AQA, 2018-07)
Catanionic surfactants are a class of amphiphile which result from the equimolar mixture of a cationic and an anionic surfactant, where the salt formed by the counterions is removed. In our group, for the first time, we ...
