“…These parameters can be mainly regulated by surfactants which act as soft templates or nanocontainers. The preparation of gold, silver and gold-silver alloy nanoparticles by seedmediated method using gemini surfactant has been described by Tiwari et al [242]. The obtained NPs were stable and were characterized by UV-vis, XPS, TEM, energy dispersive spectroscopy (EDS) and zeta potential techniques.…”

Gemini cationic surfactants are compounds which are composed of two hydrophilic head groups and two hydrophobic tails linked by a spacer at the head groups or closed to them. The spacer can be either hydrophobic or hydrophilic. It can be rigid or flexible. The neutral charge of the molecule is retained by the presence of organic or inorganic counterions. Critical micelle concentrations (CMCs), surface tension (γ) and minimal inhibitory concentration (MIC) are dozen times lower than corresponding parameters of monomeric surfactants. The unique properties of gemini surfactants with a wide range of hydrophiliclipophilic balance (HLB) make them a very useful, innovative material in detergents, cosmetics, personal care products, additives for paints and coatings, biocides, material science, organic synthesis, pharmacy, textiles, enhanced oil recovery, nanotechnology, petroleum and many other branches of life. A large number of papers concerning gemini surfactants have been published so far. This review presents a synthetic look at current work devoted to structure, synthesis and applications of gemini surfactants.

“…Surfactants can play an important role in the synthesis and stabilization of metal nanoparticles (NP); they can as well control the size and shape of the NPs depending on their types and lengths [67][68][69][70][71][72]. Cationic surfactants have potential effect on the above process.…”

“…Sharma et al reviewed the recent development of gemini surfactants (Sharma et al, 2017). Because of their unique properties, gemini surfactants are used in different areas, such as household, medicine, nanoscale materials, as corrosion inhibitors in petrochemical industries (Karanwal et al, 2015;Singh et al, 2016;Zhang et al, 2011), nonviral vectors to deliver DNA for gene therapy (Ahmed et al, 2016;Cardoso et al, 2015;Fisicaro et al, 2014), micellar catalysis (Kumar and Abdul Rub, 2017;Kumar et al, 2015), synthesis of nanoparticles (Negm et al, 2015;Tiwari et al, 2015), oil recovery (Kamal, 2016), potential drug carriers (Mahajan and Mahajan, 2013), and so on.…”

A group of novel sugar‐based gemini surfactants, N, N′‐bis(2‐hydroxy‐3‐alkyloxylpropyl) ‐N, N′‐bis(gluconylamide)‐ethylenediamine (alkyl: n‐C8H17, n‐C12H25, n‐C14H29, n‐C16H33), were synthesized and characterized. Their surface properties, including surface tension, γ, critical micelle concentration, CMC, maximum surface excess, Гmax, minimum area per molecule, Amin, and standard free energy of micellization and adsorption, normalΔGm0 and normalΔGads0, were investigated. The members of this family could reduce the surface tension of water to approximately 20–25 mN m−1 at the concentration level of 10−5 mol L−1, considerably lower than that commonly achieved with monomeric surfactants. Their adsorption and aggregation behavior were further studied by means of dynamic light scattering and X‐ray diffraction. The relationship of the aggregate size of the synthesized gemini surfactants with the length of the hydrocarbon chain and their concentration was discussed.
