Peptide-Based Nanomaterials

Dear Colleagues,

As endogenous molecules composed of a few to dozens of amino acids, peptides with superior biocompatibility, targeting, and specificity have become favorable candidates for the treatment and diagnosis of critical diseases. However, in the face of the complex human environment, low affinity and poor stability limit the applications of free peptides. The introduction of appropriate nanomaterials is expected to alleviate these problems. On the one hand, as an easily modified molecule, a peptide can be conjugated with a variety of nanomaterials to make up for its defects. On the other hand, the permutation and combination of different amino acids endow the peptides with diverse secondary structures and make them have different chemical characteristics such as hydrophilicity, hydrophobicity, and positive and negative electrical properties, thereby giving them the ability to self-assemble. Whether peptide-functionalized or peptide self-assembled, peptide-based nanomaterials have attracted widespread attention due to their multiple functions with enhanced biochemical properties. In addition, as a source issue, the screening of peptides and peptide-based nanomaterials is also a hot spot of our attention. In particular, advanced technologies related to computer science such as artificial intelligence will arouse great interest. This Special Issue is dedicated to featuring the latest research that is ongoing in the field of peptide-based nanomaterials. Therefore, we welcome the discussion of the screening and design of novel peptide-based nanomaterials and the applications of these materials in disease diagnosis and treatment.

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. Molecules 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 2700 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.
