The paper presents the analysis of micellization behavior cationic gemini surfactants with similar structures varying atom number in spacer: heptylene-1,7-bis(dimethyloctylammonium) bromide (8–7–8) and octylene-1,8-bis(dimethyloctylammonium) (8–8–8) water water–ethanol solvent mixed media. Experiments were carried out by using conductometric method within temperature range 288.15–323.15 K. values parameters thermodynamic functions aggregation [critical micelle concentration (cmc), degree...
This study provides deep insight into the adsorption process of doxorubicin onto different types carbon nanotubes that have been proved to show attractive properties as a drug delivery system. The main aim work was propose probable mechanisms and interactions between anticancer surface modified pristine at blood pH. were oxidized optimize absorbance efficiency relative multiwalled nanotubes. isotherm system well described by Temkin equation. It confirms in studied involves also hydrogen...
The subject of this study concerns the aggregation process cationic gemini surfactants with formulas 8–6–8 and 8–12–8. Conductivity measurements carried out within temperature range (288.15–323.15) K made it possible to determine values critical micelle concentration dissociation degree micelles for system investigated range. Using various models, basic thermodynamic functions (enthalpy, entropy, free Gibbs energy micellization) were determined. data obtained allowed us assess their...
In this article, a novel method of simultaneous carborane- and gadolinium-containing compounds as efficient agents for neutron capture therapy (NCT) delivery via magnetic nanocarriers is presented. The presence both Gd B increases the efficiency NCT using enhances selectivity. These factors make not only efficient, but also safe. Superparamagnetic Fe3O4 nanoparticles were treated with silane then polyelectrolytic layer was formed further immobilization agents. Fourier-transform infrared...
The article discusses the release process of doxorubicin hydrochloride (DOX) from multi-wall carbon nanotubes (MWCNTs). studies described a probable mechanism and actions between surface functionalized MWCNTs anticancer drugs. (CNTs) has been modified via treatment in nitric acid to optimize adsorption process. modification efficiency physicochemical properties MWCNTs+DOX system were analyzed by using SEM, TEM, EDS, FTIR, Raman Spectroscopy UV-Vis methods. Based on computer simulations at pH...
The aim of this study was to investigate the self-assembly process for m-8-m gemini surfactants, m = 8 and 12, in water, using microcalorimetric titration method within temperature range 283.15–343.15 K. enthalpy micellization (∆H mic) critical micelle concentration (c.m.c.) have been calculated by modified sigmoidal Boltzmann equation. Other thermodynamic parameters ∆G mic, ∆S ∆C p,mic, associated with were determined on basis calorimetric results applying pseudo-phase separation model....
Abstract A group of cationic gemini surfactants (bisquaternary ammonium bromides) with different spacer chain lengths (8–6–8, 8–7–8, 8–8–8, 8–9–8) was investigated, paying special attention to antimicrobial and the cytotoxic properties as well their activity during long‐term storage. It shown that compounds investigated exhibit excellent against Gram‐positive bacteria ( Staphylococcus aureus ) Gram‐negative Pseudomonas aeruginosa antifungal Candida albicans ). The tested had differential...
A rapid amplification of algal population has a negative impact on the environment and global economy. Thus, control proliferation is an important issue effective procedures which reduce blooms fouling are highly desired. Gemini surfactants considered to have low environmental impact, therefore they seem be promising group detergents could in water systems. Furthermore, due their emulsifying properties replace algaecides added antifouling paints decrease algae adhesion various surfaces. In...
The development of methods for targeted delivery payload is a rapidly developing area research.For this reason, iron oxide nanoparticles have potential to be used in substances by using external magnetic field. However it necessary develop their modification, which will lead the pos-sibility immobilization payloads with required concentration therapeutic use. In article, supermagnetic (Fe3O4) were modified silanes such as (3-chloropropyl)-trimethoxysilane, (3-mercaptopropyl)trimethoxysilane,...
The enthalpies of solution cyclic ethers [1,4-dioxane, 12-crown-4 (12C4), 15-crown-5 (15C5) and 18-crown-6 (18C6)] in N,N-dimethylformamide + methanol (DMF MeOH) mixtures have been measured at 298.15 K. On the basis obtained data, effect acid–base structure–energetic properties DMF MeOH on enthalpy these has analyzed. results compared with analogous data concerning water W) mixtures.
