Special Issue Information

Dear Colleagues,

Marine organisms have developed unique mechanisms for the acquisition, sequestration, and utilization of essential trace metals in the marine environment. Many marine secondary metabolites contain functional groups that can complex metals and a great number of marine natural products possess ion chelating ability, such as cyclic peptides, ionophores, siderophores, etc. Studies of isolation, structural elucidation, synthesis and properties of coordination of metal- chelating marine natural products is a topic of increasing interest nowadays due to their potential applications such as agents for medical uses, chelate contrast agents for molecular imaging, bioremediation, metal coordination in surface adhesion, etc. Although some of them may be involved in the uptake and transport of metal ions present in the marine environment, however the real reason of their production is not fully understood. Current investigation is also focused on their structures, dynamics and reactivities and on studies to establish their biological functions. As Guest Editor of this Special Issue of Marine Drugs, I invite you to provide recent advances in all the aspects dealing with marine metabolites and metal ion chelation.

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. Marine Drugs 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 2900 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.

In this paper, we present the fabrication and characterization of new chitosan-based membranes while using a new biotechnology for immobilizing alkaline phosphatase (ALP). This technology involved metal ions incorporation to develop new biopolymeric supports. The chemical structure and morphological characteristics of proposed membranes were evaluated by infrared spectroscopy (FT-IR) and the scanning electron microscopy technique (SEM). The inductively coupled plasma mass spectrometry (ICP-MS) evidenced the metal ion release in time. Moreover, the effect of Mg2+ on the enzymatic activity and the antibacterial investigations while using Gram-negative Escherichia coli and Gram-positive Staphylococcus aureus bacteria, hemolysis, and biocompatibility behavior were studied. Immobilizing ALP into the chitosan membranes composition followed by the incorporation of Mg2+ led to polymeric supports with enhanced cellular viability when comparing to chitosan-based membranes without Mg2+. The results obtained evidenced promising performance in biomedical applications for the new biopolymeric supports that are based on chitosan, ALP, and metal ions. Full article
