Transition from micelle to vesicle in aqueous mixtures of anionic/zwitterionic surfactants studied by fluorescence, conductivity, and turbidity methods

Molecular Insights into the Interaction between α-Synuclein and Docosahexaenoic Acid

“…40,42,82 Two series of pyrene fluorescence emission measurements (1 μM) were obtained, increasing the FA concentration from 0 to 500 μM in the absence or in the presence of α-syn (5 μM). Fluorescence emission spectra were recorded in PBS (pH 7.4) using an excitation wavelength of 335 nm, and the intensity of the maxima corresponding to the first (I 1 ) and the third (I 3 ) vibronic band, located near 373 and 384 nm, respectively, was measured.…”

Synergistic Behavior Between Zwitterionic Surfactant α‐Decylbetaine and Anionic Surfactant Sodium Dodecyl Sulfate

“…[2]. Another important reason is that zwitterionic surfactants are compatible with a wide variety of ionic and nonionic surfactants [3][4][5][6] and some interesting properties have been observed [7,8]. Several reports [8][9][10][11][12] have revealed that zwitterionic surfactants often have a strong interaction with anionic surfactants in aqueous solution.…”

Surface properties and morphologies of pheohydrane/liquid crystal moisturizer product

“…Conductivity is a measure of the current passing through a solution. The magnitude of the conductivity is proportional to the number of ions in the solution [11], and it is related to the electrode plate size. If the surface of the electrode plate is contaminated, thereby resulting in a change in the area of the electrode plate, the data will not be accurate.…”

“…The cohesive forces between liquid molecules are responsible for the phenomenon known as surface tension. The molecules at the surface do not have other like molecules on all sides; consequently, they cohere more strongly to those directly associated with them on the surface [11]. This behaviour leads to the formation of a surface ''film,'' making it relatively more difficult to move an object through the surface than to move it when completely submersed [12].…”
