Special Issue Information

Dear Colleagues,

Gold and silver nanoparticles are among the wide variety of core materials available. Coupled with tunable surface properties in the form of an inorganic or inorganic–organic hybrid, they have been reported as an excellent material for a broad range of next-generation applications. Gold and silver nanoparticles still bring new application opportunities for nanotechnology.

This Special Issue on “Green Synthesis and Application of Gold and Silver Nanoparticles” will gather interdisciplinary works in the fields of material, biomedical, and chemical sciences. The Special Issue is dedicated to the novel synthesis of nanomaterials by biological approaches, as well as challenges such as the description of the mechanism formation of nanoparticles in various systems, and their stability and physicochemical characteristics, targeting novel applications of green nanomaterials in biological system. Advances in such materials will demonstrate specific properties and versatile applications in the future.

It is my pleasure to invite you to submit original research manuscripts within the scope of this Special Issue. Short communication and state-of-the-art reviews will also be greatly appreciated.

You may choose our Joint Special Issue in Molecules.

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. Chemistry 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 1800 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.

Nanoparticle engineering via plants (green synthesis) is a promising eco-friendly technique. In this work, a green protocol was applied to the preparation of silver, zinc, and selenium nanoparticle solutions supported by the extracted aerial parts of Pulicaria undulata. The formation of nanoparticles in the solution was characterized using phytochemical analysis, and UV-visible, TEM, and zeta-potential spectroscopy. In addition, various biological activities were investigated for the extract of P. undulata and the produced nanoparticles (selenium, silver, and zinc), including antioxidant, antimicrobial, and cytotoxic activities. The volatile components of the extracted constitute verified the fact that twenty-five volatile components were characterized for the majority of abundant categories for the fatty acids, esters of fatty acids (59.47%), and hydrocarbons (38.19%) of the total area. The antioxidant activity of P. undulata extract and metal nanoparticles was assessed using DPPH assay. The results indicated reduced potency for the metal nanoparticles’ solutions relative to the results for the plant extract. The cytotoxicity of the investigated samples was assessed using an MTT assay against various tumor and normal cell lines with improved cytotoxic potency of the solutions of metal nanoparticles, compared to the plant extract. The antimicrobial activity was also estimated against various bacterial and fungal species. The results confirmed amended potency for inhibiting the growth of microbial species for the solutions of metal nanoparticles when compared to the extracted aerial parts of the plant. The present study showed that green synthetized nanoparticles using P. undulata have various potential bioactivities. Full article
