Particles and particle films are provided. In certain examples, particles produced from a single phase process may be used to provide industrial scale synthesis of particles for use in devices such as printed wiring boards. The particles, in particular silver particles are produced by a process comprising: mixing a metal or a metal salt with a capping agent in a single phase solution; and adding a reducing agent to the single phase solution to produce capped nanoparticles. La présente invention concerne des particules et des films de particules. Dans certains exemples, les particules produites à partir d'un procédé à phase unique peuvent être utilisées pour permettre la synthèse à échelle industrielle de particules à utiliser dans des dispositifs tels que des cartes à circuit imprimé. Les particules, en particulier des particules d'argent, sont produites par un procédé consistant à mélanger un métal ou un sel métallique avec un agent de coiffe dans une solution à phase unique et ajouter un agent de réduction à la solution à phase unique pour produire des nanoparticules coiffées.
