A place exchange reaction between 11-mercaptoundecanoic acids (MUA) and cetyltrimethylammonium bromide (CTAB)-protected gold nanorods (GNRs) was conducted inside an ionic exchange resin; this modification resulted in functional gold nanorods soluble in both polar and nonpolar organic solvents.

Highly PL carbon quantum dots (CQDs) were successfully prepared from C60 by introducing CTAB and H2O2 in aqueous NaOH under hydrothermal conditions. The CQDs displayed a nanoparticle aggregation-induced emission enhancement (NP-AIEE).

Mesoporous silica nanomaterials of different shapes (film, platelet, sphere, rod) were synthesized simply by tuning the mole ratio of dual cationic surfactant templates, cetyltrimethylammonium bromide (CTAB) and tetrabutylammonium iodine (TBAI). The film showed the most potent antibacterial activity against mycobacteria.

Abstract Mixing hydrocarbon surfactants with fluorocarbon is still an important strategy to improve the economic benefits and performances of expand their range application. Herein, we prepared a novel kind hydrocarbon-fluorocarbon surfactant mixtures via mixing cationic surfactant, cetyltrimethylammonium bromide (CTAB), tri-block nonionic short-chain (F 9 EG 13 F ) in aqueous solution. The res...

The uncertainties in ZnO-mediated toxicity and particle stability a biological system remain challenge mitigate against deployment as next-generation nanoparticles (NPs), especially biomedical applications. With that perspective, the present study investigates surface chemical properties of ZnO NPs coated with three different surfactant biomolecules, namely polyethylene glycol (PEG), cetyltrime...

DNA and cetyltrimethylammonium bromide (CTAB) have been used to prepare gel particles for controlled release studies. This article reports on the release of DNA and CTAB in four different solutions: in sodium bromide, in strong acid, pH 2 and pH 9 solutions for salmon testes DNA-CTAB gel particles. Also, compares results at extreme acid media and 10 mM NaBr solution with higher molecular weight...

BACKGROUND The impact of gold nanoparticles on cell viability has been extensively studied in the past. Size, shape and surface functionalization including opsonization of gold particles ranging from a few nanometers to hundreds of nanometers are among the most crucial parameters that have been focussed on. Cytoxicity of nanomaterial has been assessed by common cytotoxicity assays targeting enz...

Composite materials made of mesoporous oxide thin films containing metallic nanoparticles are of high interest in various fields, including catalysis, biosensing and non-linear optics. We demonstrate in this work the fabrication of such composite materials containing a sub-monolayer of gold nanoparticles (GNPs) of various shapes covered with mesoporous silica thin films. Additionally, the shape...

This paper describes studies of surface modification of a natural Chilean zeolite with cetyl trimethylammonium bromide (CTAB), to investigate the adsorption efficiency for the removal from aqueous solution of an anionic surfactant, sodium dodecyl benzene sulfonate (SDBS), at bench scale. Modification of the zeolite with CTAB (named ZMS) was based on the external cation exchange capacity (ECEC) ...
