Special Issue Information

Dear Colleagues,

In the preceding decades, a great attention has been devoted by the scientific community to the nanotechnology area, a research field which is focused on the design and development of a large and diversified class of composites, termed nanomaterials. These possess at least one dimension in the nanometer range. The miniaturization process endows these nanometric products with properties that differ compared to those of bulk materials or corresponding atoms and several efforts have been made to understand the correlation between the system architecture and the dependent chemical–physical properties, including magnetic, optical, and eletrical properties. Suitable and highly sophisticated top-down and bottom-up approaches have allowed researcher to obtain nanomaterials with suitably tuned characteristics like size and shape (e.g., spherical, tubular, star, rods, wires etc.). The same concepts have been employed to realize hybrid nanodevices based on the combination of multiple nanomaterials with different nature and peculiarities.

The results obtained in that field have given rise to a class of novel materials and devices with great potential for use in the nanotechnology field, with ultimate applications in electronics, energy, biomedicine as well as manufacturing and space industries.

The present Special Issue is seeking to outline the state of art and the recent innovations in the design, synthesis, characterization of these systems, as well as their possible applications in the nanotechnological field.

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.

Over the past decade, the attention of researchers has been drawn to materials with enzyme-like properties to substitute natural enzymes. The ability of nanomaterials to mimic enzymes makes them excellent enzyme mimics; nevertheless, there is a wide berth for improving their activity and providing a platform to heighten their potential. Herein, we report a green and facile route for Tectona grandis leaves extract-assisted synthesis of silver nanoparticles (Ag NPs) decorated on Mg-Al layered double hydroxides (Mg-Al-OH@TGLE-AgNPs) as a nanocatalyst. The Mg-Al-OH@TGLE-AgNPs nanocatalyst was well characterized, and the average crystallite size of the Ag NPs was found to be 7.92 nm. The peroxidase-like activity in the oxidation of o-phenylenediamine in the presence of H2O2 was found to be an intrinsic property of the Mg-Al-OH@TGLE-AgNPs nanocatalyst. In addition, the use of the Mg-Al-OH@TGLE-AgNPs nanocatalyst was extended towards the quantification of Hg2+ ions which showed a wide linearity in the concentration range of 80–400 μM with a limit of detection of 0.2 nM. Additionally, the synergistic medicinal property of Ag NPs and the phytochemicals present in the Tectona grandis leaves extract demonstrated notable antibacterial activity for the Mg-Al-OH@TGLE-AgNPs nanocatalyst against Gram-negative Escherichia coli and Gram-positive Bacillus cereus.
