Special Issue Information
Dear Colleagues,
The increasing presence of microplastics and engineered nanomaterials in our environment and biological systems has become a pressing concern for human and ecological health. These emerging contaminants, which are characterized by their nanoscale dimensions, large surface-area-to-volume ratios, and diverse chemical compositions, can readily enter the body through inhalation, ingestion, or dermal exposure. Once internalized, these particles have the capacity to traverse epithelial and endothelial barriers, accumulating in various organs and disrupting essential physiological processes.
Mounting evidence indicates that microplastics and nanomaterials may induce oxidative stress, inflammation, mitochondrial dysfunction, endoplasmic reticulum stress, and autophagy dysregulation. Furthermore, the interaction of these cells with the immune system, gut microbiota, neural circuits, and endocrine systems can result in subtle but chronic physiological disturbances. These effects may be of particular concern to vulnerable populations, such as children, the elderly, or individuals with pre-existing conditions. Despite the growing awareness of this phenomenon, the precise molecular and cellular mechanisms underlying these effects remain largely elusive and urgently need clarification.
The present Special Issue has been conceived with the aim of exploring the mechanistic basis of how microplastics and nanomaterials affect biological systems, with a focus on physiological functions at cellular, tissue, organ, and systemic levels. Contributions employing in vitro models, animal studies, omics technologies, and imaging techniques to investigate uptake, bio-distribution, biotransformation, signaling pathway disruption, and long-term toxicity are welcomed. The submission of review articles that synthesize current knowledge and propose future research directions is also highly encouraged. The overarching objective is to facilitate the creation of evidence-based guidelines for environmental safety, risk assessment, and potential biomedical applications.

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 250 words) can be sent to the Editorial Office for assessment.
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. Life 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 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.
