Metal nanoparticles are full of contrasts: old but terribly contemporary, simple but present in highly sophisticated systems. From their beginning with Faraday for more than 150 years to current days, metal nanoparticles are present and important in our life, thanks to their optical properties, or use as drugs and antiseptics to give only some examples. Interestingly, today it is no more the question to create a nanoparticle – many procedures are known – but to know how to tailor their properties for a specific application and to understand how they form which is important. Size, shape, colloidal properties and optical activity control are prerequisites for various applications. Many parameters can be tuned to obtain the desired properties like template choice, temperature of synthesis, pH etc., making the Chemist work difficult but exciting and requiring a lot of inspiration and creativity. A further step of complexity can be found in metal nanoparticles like Janus-type, core-shell and nanoalloys, which are required for advanced analytical techniques and new materials preparation. In this field many questions are open but answers are scarce. Altogether, a lot remain to be done: design of new stabilizing ligands and templates, better knowledge of growth and self-assembly processes, and new analytical methods are required to answer the questions raised by this exiting research area. We hope that this special issue will contribute to solve open questions and open new tracks in this fascinating and rapidly moving area.
