Special Issue "Antimicrobial Nanomaterials and Nanotechnology"
A special issue of Nanomaterials (ISSN 2079-4991).
Deadline for manuscript submissions: closed (10 November 2016)
After more than 20 years intensive investments, nano-materials as a foundation of nanotechnology have been developed widely in all sciences and engineering fields deeply rooted into applications. The theme of antimicrobial nanomaterials are defined by the particles with sizes smaller than that of 100 nm, and kill some of the bio-organism pathogens such as bacteria and viruses while inhibiting their biofilm formation. Antimicrobial nanoparticles are the truly cross-disciplinary theme, not just within the physics-materials-chemistry but also cross to biological, biomedical, healthcare and environmental sciences. Their applications also concerned the social and economic communities.
Some identified nano-materials or nano-scaled materials may have shown different levels of antimicrobial ability. However, more investigations have been focused on the nano-scaled materials. Hence, the "bulk with nano-structures" may be a virgin field for exploration considering the costs and toxicity issues that associated to the nanoparticles. A proof of nano-structures that kill or inhibit microbes is needed for a better solution for the antimicrobial as well as its resistance, the worldwide challenges from both bacterial and the viruses, by uses of a more "nature" and sustainable way to tackle the challenges.
The Special issue will present comprehensive research outlining progress on the antimicrobial nanomaterials and nanotechnology. We welcome papers (original research or reviews) from all disciplines where antimicrobial nanomaterials are of interest, with emphasis on the emerging bulk with nano-structures and antimicrobial mechanisms.

Title: Antimicrobial polymers in the nano-world
Author: Marta Fernandez-Garcia
Affiliation: Instituto de Ciencia y Tecnologia de Polimeros (ICTP-CSIC), C/ Juan de la Cierva 3, 28006-Madrid, Spain
Abstract: Infections are one of the main concerns of our era due to the antibiotic-resistant infections and the costs increasing in the health-care sector. In this context polymers are presented as a great alternative to combat these problems since their mechanisms of action differ from the antibiotics. Therefore, the microorganisms’ resistance to these materials is avoided. This article presents the different strategies that combine the nanoscience and nanotechnology in the polymer world against contaminations from bacteria, fungi or algae.
Title: Micro-/Nanostructured PHB coatings as protective coatings for packaging papers
Authors: Vibhore Rastogi, Pieter Samyn
Abstract: This study reports on the development of bio-based hydrophobic coatings for packaging papers by following the two approaches. In first approach, structured polyhydroxybutyrate or PHB particles in micrometer range were prepared through the phase-separation technique and later transferred over the paper by dip-coating method. This approach only allowed the partial surface coverage of structured PHB particles over the papers resulted in the development of second approach. In second approach, two step dip-coating coating formulation comprises PHB as coating pigment, nanofibrillated cellulose or NFC as binder, and plant wax as hydrophobizing agent. A synthesis procedure for the formulation of PHB particles in aqueous environment has first been optimized. In the next step, filter paper was dip-coated in PHB/NFC aqueous suspensions with different concentrations of NFC and the latter was additionally sized with wax solution, to have a final water contact angle of 152°. Morphological characterizations on coated papers were carried out by SEM and 3D-laser profilometry to visualize the effect of different NFC concentrations as binder. It was observed that the fibrillar cellulose network is playing a key role in the retention of PHB particles at the paper surface. This effect was further confirmed by chemical analysis of coated papers by Raman mapping. The coated papers can serve as protective layers with improved hydrophobicity for food packaging applications.
