Bacterial Synthesis of Metal Nanoparticles

Dear Colleagues,

Metallic nanoparticles are experiencing growing attention due to their critical benefits in industrial sectors such as agriculture, biomedicine, cosmetics, electronics and energy industries. The bioproduction of metallic nanoparticles (MeNPs) is a sustainable method since it releases less contaminant compounds and demands less energy than the traditional physiochemical methods. Bacteria present an enormous potential as biofactories for MeNP production, by transforming metallic ions into MeNPs with a narrow size distribution and repetitive shapes; however, important challenges have to be solved to compete with the physiochemical methods of production. This Special Issue aims to publish innovative articles dealing with the following topics:

1. Molecular determinants and mechanisms involved in MeNP production: description of new molecular actors involved in MeNPs.
2. Novel bacterial chassis for MeNP production. Isolation of new biofactories for MeNPs production capable of bypassing some of the existing limitations. Synthetic biology strategies to produce robust bacteria that are more efficient in MeNP production are welcome.
3. Methods to increase the MeNP polydispersity. Protocols able to achieve stable systems for biosynthesize MeNPs in size and shape.
4. Scaling of the MeNP production. Protocols of scaling the production yields and large-scale production to decrease the actual distance with the prevailing industrial requirements.
5. Description of innovative or undiscovered applications of MeNPs produced in bacteria.

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. International Journal of Molecular Sciences is an international peer-reviewed open access semimonthly journal published by MDPI.

Please visit the Instructions for Authors page before submitting a manuscript. There is an Article Processing Charge (APC) for publication in this open access journal. For details about the APC please see here. 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.
