Dear Colleagues,

Nanotechnology has come a long way in the last two decades. Its wide diversity of applications covering areas as diverse as medicine, industrial processes, electronics, cosmetics, agriculture, food, metallurgy, and construction materials can carry risks that remain unknown. Its effects on living beings and the environment constitute a new factor that has increasingly attracted attention over the years, giving rise to nanotoxicology. Since the first toxicity effects we realized, a new generation of hybrid nanomaterials developed and the lack of knowledge seems to be even greater. To date, there is significant uncertainty of its nanotoxicology aspects regarding specific properties. Additionally, the relevant factors related to the handling of nanomaterials and their subsequent staging continually grow. Fortunately, international associations have intensified their efforts in gathering information to lessen the possible risks and improve nano-prevention knowledge. It is essential to maintain a constant contribution to the progress based on new diagnostic tools. Exposure to nanomaterials is one of the primary reasons of death, even from prenatal ages. Today, the impact of new nanomaterials is unknown. Given the magnitude of the toxicity risks, it is urgent to elucidate its effects on living beings and the environment. The possible implications at the cardiovascular, pulmonary, or neurological level must be uncovered, and the problem must tackled from the early stages of nanomaterial synthesis by opting for safe alternative methods. There is, thus, an urgent need to report the advances in the evaluation of nanoengineered materials, realizing their effects at the organism and cellular level, including the consequences of their environmental exposure.

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 submissions that pass pre-check are 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 semimonthly 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 2900 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.
