Special Issue Information

Dear Colleagues,

The risk evaluation and characterisation of nanomaterials (NMs) is crucial if there is potential for human exposure, exposure to other species or the environment to nanomaterials. To assess and characterise the environmental risks associated with nanomaterials must be based on a relevant assessment of exposure and effects. The approach assuming chemical equilibrium between test organisms and the surrounding environment, traditionally used for dissolved chemicals, is not valid for NMs. Consequently, reliable risk assessment of NMs requires proper innovative chemical analytical and ecotoxicological methods. Based on these methodologies, developing new risk evaluation approaches is also necessary with nano-specific concerns. Life-cycle consideration in exposure and effect assessment is one of the major issues for a better understanding of the potential environmental health consequences of nanomaterials over the entire life cycle.

The present Special Issue in Nanomaterials aims to present the current state of the art in the environmental risk assessments and characterisation of nanomaterials. This Issue addresses the novel methodologies that may be used to assess the relevant and adequate risks to the environment. The problem-specific use of integrated testing strategies and the knowledge of modes or mechanisms of action will also be discussed.

In the present Special Issue, we will present contributions from leading research groups from various related research areas to give a balanced picture of the current state of the art in this discipline.

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 2600 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.

Co-abietate and Cu-abietate complexes were obtained by a low-cost and eco-friendly route. The synthesis process used Pinus elliottii resin and an aqueous solution of CuSO4/CoSO4 at a mild temperature (80 °C) without organic solvents. The obtained complexes are functional pigments for commercial architectural paints with antipathogenic activity. The pigments were characterized by Fourier-transform infrared spectroscopy (FTIR), mass spectrometry (MS), thermogravimetry (TG), near-edge X-ray absorption fine structure (NEXAFS), X-ray photoelectron spectroscopy (XPS), scanning electron microscopy (SEM), and colorimetric analysis. In addition, the antibacterial efficiency was evaluated using the minimum inhibitory concentration (MIC) test, and the antiviral tests followed an adaptation of the ISO 21702:2019 guideline. Finally, virus inactivation was measured using the RT-PCR protocol using 10% (w/w) of abietate complex in commercial white paint. The Co-abietate and Cu-abietate showed inactivation of >4 log against SARS-CoV-2 and a MIC value of 4.50 µg·mL−1 against both bacteria Staphylococcus aureus (S. aureus) and Escherichia coli (E. coli). The results suggest that the obtained Co-abietate and Cu-abietate complexes could be applied as pigments in architectural paints for healthcare centers, homes, and public places. Full article
