مقاله Preparation of Ag nanoparticles with triethanolamine as reducing agent and their antibacterial property : تی پی بین

خلاصه مقاله

Hydroxide ions play a crucial role in the reduction of Ag⁺ ions with alcohol. In this paper, Ag nanoparticles were prepared with triethanolamine (TEA) serving as reducing agent and alkali for the first time. The effects of stabilizer, mole ratio of AgNO₃/TEA, temperature and AgNO₃ concentration on the particles, as well as the antibacterial performance of the particles, were studied. The results showed that, PEG and PVP are effective for inhibiting the growth of particles, and Ag particles about 40 nm in size were obtained. The effects of TEA amount on the particles are negligible. On rising temperature, the particles size increase and the particles become more regular. With the increased AgNO₃ concentration, the particles tend to large and poly-dispersed. The Ag nanoparticles show excellent antibacterial property.

Colloids and Surfaces A: Physicochemical and Engineering Aspects

Colloids and Surfaces A: Physicochemical and Engineering Aspects is an international journal devoted to the science underlying applications ofcolloids and interfacial phenomena. The journal aims at publishing high quality research papers featuring new materials or new insights into the role of colloid and interface science in (for example) food, energy, minerals processing, pharmaceuticals or the environment.Criteria for publication in Colloids and Surfaces A are novelty, quality and current interest. Manuscripts which only make routine use of or minor extensions to well established methodologies (e.g. fitting adsorption data to a Langmuir or Freundlich isotherm) are no appropriate for the journal.
