Special Issue Information
Dear Colleagues,
Metallic nanoparticles (MNPs) have been known about since ancient times, when they were used for decoration. To date, the fascination with them has not diminished, and there is a growing interest in their application for the creation and design of extremely sensitive and specific biochemical nanosensors (e.g., glucose, phenol, H2O2, cholesterol, urea, lactic acid, DNA, proteins, breast cancer markers, etc.), additives for bone scaffolds, protective coatings for implants (laryngology, cardiology, orthopedics, or stomatology), drug and gene carriers, nano-adjuvants, biomedical imaging, and some chemical/physical properties (e.g., pH). MNPs also find various applications in catalysis, optics, electronics, food processing, cosmetics, high-density information storage, energy conversion, and construction (e.g., roofs, ceilings), among others. This wide application is due to the properties of MNPs, including their large surface area and versatile surface chemistry, controlled toxicity, good biocompatibility and biodegradability, chemical resistance, thermal stability, and ease of application.
By suitably selecting the nanostructure and composition of MNPs, it is possible to obtain not only biocompatible nanoparticles, but also nanoparticles that exhibit selective biological/chemical activities with respect to the selected compounds that interact (via adsorption and desorption processes) with a surface of interest (reaction at the solid–liquid(gas) interface). The interactions among biological, organic, and inorganic molecules and a metal surface are a central topic in biotechnology and biochemistry. Since biotechnological research relates to processes at the molecular and cellular level, the structure and properties of the interface must be designed and controlled at this level. Therefore, the metal interface is often used in the form of metallic nanoparticles obtained under controlled conditions in an aqueous medium via chemical, electrochemical, and laser ablation methods, as well as by the sol–gel method, the hydrothermal method, co-precipitation, microwave-assisted synthesis, or the “green chemistry” method using prokaryotic bacteria or eukaryotic fungi and plants.
The nanoscale properties of the interface between the biological and physical systems are a common theme in many different devices. Therefore, there has been a constant search for MNPs with improved properties, constant research on the development of their ecological, low-cost and efficient synthesis methods, and numerous studies on novel application areas or attempts to understand the relationship between their structure and properties. The aim of this Special Issue is to provide insights into recent advances in the above research areas, focusing on the advantages, limitations, and future directions of the application of metallic nanoparticles in molecular biology and molecular medicine. Researchers are invited to share their ideas and findings on these exciting topics. Original research papers and review articles are welcome.

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.
