Special Issue Information
Dear Colleagues,
The interaction of graphene with living cells opens up several interesting fields of application. Due to their hydrophobic nature, thin layers of graphene can penetrate biological membranes. Graphene flakes or sheets are also known to wrap around cells. These processes can lead to cellular damage, both via disruption of the membrane lipid bilayer or induction of oxidative stress. Bacteria are especially susceptible to damage caused by graphene and this has recently led to interesting advances in antibacterial applications of graphene-based nanocomposites. Another aspect of graphene useful in bio-applications is its extreme sensitivity to electrical perturbations. Charged moieties approaching the graphene sheet affect its electrical conductivity, and this can be readily measured. Based on this property, there are efforts to develop various graphene-based nano-devices that can operate as sensors. These range from sensors of small molecules/metabolites, peptides and proteins, to detection of whole bacterial cells attaching to surfaces.

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 2400 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.
