In the landscape of the design of carbon nanomaterials, the fine-tuning of their functionalities and physico-chemical properties has increased their potential for therapeutic, diagnostic, and biosensing applications. In this editorial, we will provide a brief overview of the contents of this Special Issue. In particular, nanoplatforms originating from the synergistic combination of carbon-based nanomaterials (i.e., nanotubes, graphene, graphene oxide, carbon quantum dots, nanodiamond, etc.) with various functional molecules such as drugs, natural compounds, biomolecules, polymers, metal nanoparticles, and macrocycles that have useful applications in drug delivery, multi-targeted therapies, theranostic as well as scaffolds in tissue engineering, and as sensing materials have been selected for publication as Articles or Mini Reviews. The variety of applications covered by the nine articles published in this Special Issue of Nanomaterials are proof of the growing attention that the use of carbon nanomaterials in the biomedical/pharmaceutical field has received in recent years. We hope that readers find the contents of this Special Issue useful for their research, which is aimed to advance carbon nanomaterials from the laboratory to clinical nanomedicine.

Flexible Electronics platforms are increasingly used in the fields of sensors, displays, and energy conversion with the ultimate goal of facilitating their ubiquitous integration in our daily lives. Some of the key advantages associated with flexible electronic platforms are: bendability, lightweight, elastic, conformally shaped, nonbreakable, roll-to-roll manufacturable, and large-area. To realize their full potential, however, it is necessary to develop new methods for the fabrication of multifunctional flexible electronics at a reduced cost and with an increased resistance to mechanical fatigue. Accordingly, this Special Issue seeks to showcase short communications, research papers, and review articles that focus on novel methodological development for the fabrication, and integration of flexible electronics in healthcare, environmental monitoring, displays and human-machine interactivity, robotics, communication and wireless networks, and energy conversion, management, and storage.

This book focuses on the preparation and characterisation of polyvinyl alcohol (PVA)/ halloysite nanotube (HNT) bionanocomposite films with different HNT contents for potential use in food packaging. It examines the effect of material composition and nanofiller content on mechanical, thermal and optical properties in relation to their morphological structures, and also comprehensively describes the water resistance, biodegradation and migration rates of such bionanocomposites, as well as their barrier properties in terms of water vapour transmission, and water vapour, air and oxygen permeabilities. Further, this book discusses the use of Nielsen model and Cussler model to predict the relative permeability of bionanocomposites, demonstrating that Nielsen model is more effective and in better agreement with experimental data obtained. Lastly, it discusses the application of bionanocomposite films in food packaging to prolong the shelf life of freshly cut avocados and peaches.

This Special Issue explored different topics concerning recent progress in the synthesis and characterization of suitable innovative macromolecular systems, proposed as carriers of specific antimicrobial molecules, to be employed in the biomedical and pharmaceutical fields. Many infectious diseases are induced by omnipresent micro-organisms, including bacteria, viruses, protozoa, fungi, and algae, and, consequently, are very common, accounting for a significant share of the global disease burden. Unfortunately, antimicrobial resistance, adverse effects, and the high cost of antimicrobials are crucial health challenges worldwide. One of the common efforts in addressing this issue lies in improving the existing antimicrobial delivery systems. In this regard, nanoparticles as well as three-dimensional hydrophilic systems represent valuable tools able to ensure excellent performances. Biocompatible polymeric particles, entrapping these bioactive molecules, are capable of releasing them over a desired period of time, thereby decreasing the frequency of their administration. At the same time, these systems are able to protect antimicrobial drugs from degradation, enhancing their bioavailability. This Special Issue serves to highlight and capture the contemporary progress recorded in this field.

This Special Issue aims to highlight the dual potential of novel biocatalytic processes, where the first part is dedicated to waste valorization for the production of high value products, while the second part is focused on the detoxification of pollutants. Several examples of microbial systems employed for the valorization of waste streams derived by the forest, agricultural, and food industries or the use of whole-cell or enzyme approaches for the removal of nitrogen or dyes from industrial wastewaters are provided. Last but not least, an example of the utilization of polyhydroxyalkanoates (PHAs) was highlighted for the production of fatty acids, which were used for the enzymatic synthesis of sugar esters with antimicrobial properties.
