Dear Colleagues,

Nanomaterials. such as nanoparticles, carbon nanotubes, inorganic/polymer nanowires, graphene, transition metal dichalcogenides, and perovskites, etc., show great promise as active materials in a range of applications due to their unique and extraordinary physical and chemical properties. While designing new applications using such nanomaterials—either at a single object level or integrated in a composite form—interfaces occur inevitably and they play a vitally important role. There are different kinds of interfaces that one encounters when exploiting nanomaterials for applications: It could be between similar phases (solid–solid/liquid–liquid) or dissimilar phases (solid–liquid/solid–gas). For example, in sensors operating in liquids, the chemistry of the interface between the solid material and the medium needs to be optimized in order to achieve high sensitivity. In the fabrication of batteries and fuel cells, several material (often solid–solid) interfaces occur at the electrodes, and they have to be suitably designed in order to achieve maximum performance. Similarly, the nano(material)–bio(molecule) interface requires thorough investigation in the design of novel biomaterials as well as for realizing bioelectronic and biomedical applications.

This Special Issue is dedicated to addressing all such issues related to interfaces that are encountered when using nanomaterials for potential applications. Manuscripts (original articles or reviews) may address one or more of the following aspects:

• Modeling of interfaces, which is key to engineering and optimizing new applications;
• Fundamental aspects of nanomaterial interfaces focused on a specific application;
• Synthesis of novel nanomaterials with optimized interfaces;
• Characterization of nanomaterial interfaces;
• Development of new analytical strategies for studying nanomaterial interfaces;
• Chemical modification of nanomaterials;
• Nano-biointerfaces with focus on biomaterials, bioelectronics, and biomedical aspects;
• Interfacial phenomena in nanomaterial-based devices and systems;
• Role of interfaces in nanomaterial-based strategies for applications, including but not limited to (opto)electronic devices, (bio)sensors, (electro/photo) catalysts, batteries, fuel/solar cells, and biomaterials.

When submitting a manuscript to this Special Issue, please mention in the cover letter how the reported research addresses the focus of this Special Issue.
