Complexation of DNA with Cationic Surfactant
, 1999 Transfection of an anionic polynucleotide through a negatively charged membrane is an important problem in genetic engineering. The direct association of cationic surfactant to DNA decreases the effective negative charge of the nucleic acid, allowing the

Structural characterization of biocompatible reverse micelles using Small-Angle X-ray Scattering, 31P Nuclear Magnetic Resonance, and Fluorescence Spectroscopy [PDF]
, 2018 The most critical problem regarding the use of reverse micelles (RMs) in several fields is the toxicity of their partial components. In this sense, many efforts have been made to characterize nontoxic RM formulations on the basis of biological ...

Green Lignosulphonate as co-surfactant for wettability alteration
Petroleum Research, 2020 Surfactant flooding is one of the common tertiary method to recover remaining oil in the reservoir, by reducing the interfacial tension (IFT) between two immiscible fluids nevertheless, current surfactant forms emulsion and difficult to achieve ultra-low

Effects of miniemulsion operation conditions on the immobilization of BSA onto PMMA nanoparticles [PDF]
Polímeros, 2019 Polymer nanoparticles have been widely used in many biomedical applications, constituting a major incentive for immobilization of proteins. Poly(methyl methacrylate) nanoparticles were synthesized through miniemulsion polymerizations and used as supports

Interfacial Reactions of Ozone with Surfactant Protein B in a Model Lung Surfactant System [PDF]
, 2010 Oxidative stresses from irritants such as hydrogen peroxide and ozone (O_3) can cause dysfunction of the pulmonary surfactant (PS) layer in the human lung, resulting in chronic diseases of the respiratory tract.

Preparation of New Surfactant and Study on its Application in Ultra-low Emission of Flue Gas [PDF]
Nature Environment and Pollution Technology, 2019 In this paper, with different types of optimal surfactant monomers and potentiators mixed, the optimum formula of the new surfactant was obtained. The new surfactant with low toxicity, low cost and good dust removal effect was developed by the simulated ...

Phase behavior of pseudoternary brine/alkane/alcohol-secondary alkanesulfonates systems.Surfactant ratio effects of salinity and alcohol [PDF]
, 2008 Dodecanesulfonates (isomer mixtures) have been synthesized by the process developed in our laboratory. First, pseudoternary phase diagrams of the water or (brine) decane/ dodecanesulfonates-butan-1-ol systems were drawn and compared with those of a ...
