The production of silver nanoparticles (AgNPs) has grown in last years because of the special physicochemical properties that they present. As known, these nanomaterials are widely used in commercial products due to their antibacterial properties, which increase their intentional or unintentional release in the environment. Once there, AgNPs can suffer interactions with natural components, which can affect their final toxic effects. Therefore, characterization and quantification of these emerging pollutants in environmental and biological samples with adequate analytical methodologies is needed.
A wide range of methods and techniques to characterize and quantify nanosilver in simple matrices is available, but difficulties still exist to determine these emerging contaminants in complex samples. Moreover, the demanded analytical information can entail not only their detection and quantification, but also their particle characteristics determination. Furthermore, AgNPs can undergo transformations in different environmental compartments and living beings as a result of the interaction with some components, which makes their characterization and quantification even more difficult. Another challenge of analyzing AgNP in complex samples is the low concentration of these emerging pollutants and the co-existence of AgNPs with other silver containing chemical species (Ag(I)) or NPs of different origins (natural or manufactured) and with distinct characteristics (e.g. coating). For these reasons, the development and improvement of analytical techniques is needed.
The special Issue entitled “Silver Nanoparticles: Synthesis, Detection, Characterization and assessment in the environment” aims to cover current studies, in the field of the AgNPs synthesis and characterization. Advanced analytical methodologies and sample treatment procedures to determine and characterize AgNPS as well as to understand their behavior in the environment, are very welcome.

Manuscript Submission Information
Manuscripts should be submitted online at www.mdpi.com by registering and logging in to this website. Once you are registered, click here to go to the submission form. Manuscripts can be submitted until the deadline. All papers will be peer-reviewed. Accepted papers will be published continuously in the journal (as soon as accepted) and will be listed together on the special issue website. Research articles, review articles as well as short communications are invited. For planned papers, a title and short abstract (about 100 words) can be sent to the Editorial Office for announcement on this website.
Submitted manuscripts should not have been published previously, nor be under consideration for publication elsewhere (except conference proceedings papers). All manuscripts are thoroughly refereed through a single-blind peer-review process. A guide for authors and other relevant information for submission of manuscripts is available on the Instructions for Authors page. Nanomaterials is an international peer-reviewed open access monthly journal published by MDPI.
Please visit the Instructions for Authors page before submitting a manuscript. The Article Processing Charge (APC) for publication in this open access journal is 2000 CHF (Swiss Francs). Submitted papers should be well formatted and use good English. Authors may use MDPI's English editing service prior to publication or during author revisions.
