Special Issue Information

Dear Colleagues,

This Special Issue follows the trajectory of two earlier Special Issues in Nanomaterials, “Carbon Nanotubes and Nanosheets for Sustainable Solutions” and “70th Year Anniversary of Carbon Nanotube Discovery - Focus on Real World Solutions”.

In modern times, the earliest known scientific investigation of a nanomaterial was in 1952, when Russian scientists L.V. Radushkevich and V.M. Lukyanovich published clear images showing multiwalled carbon nanotubes (MWCNTs) with a 50 nm diameter, crediting them with the discovery of CNTs [1,2]. In the 21st century, nanotechnology holds immeasurable promise to unlock and enable significant advancements in major sectors impacting society: energy, environment, infrastructure, agriculture, healthcare, manufacturing, transportation, communications, education, and defense. A developmental backdrop common to all these sectors in society necessarily involves artificial intelligence and sustainability. With a focus on global sustainability, the United Nations set out a call for action in its Sustainable Development Goals (UN SDGs) in 2017.

Critical examples of nanotechnology in sustainability include:

(1) Energy: Nanotechnology is used to develop better batteries, such as lithium/sodium-ion batteries, with improved energy density, charge and discharge efficiency, and cycle life.

(2) Environment: Nanofiltration can be used in water treatment in homes, offices, and industries, where molybdenum disulphide (MoS2) nonporous membrane is used for energy-efficient desalination of water, filtering five times more water than conventional filters.

(3) Healthcare: Nanotechnology is helping to prevent infectious wounds through smart bandages that contain nanoparticles of blood-clotting agents, growth hormones, or sensors that can detect infection and release antibiotics. In many cases, these bandages are made from biofriendly materials that allow them to be left on the wound until they dissolve.

(4) Manufacturing: In electronics, nanotechnology enables the manufacture of tiny electronics and electric devices, for example, nanoscale transistors made out of carbon nanotubes. The extremely small scale makes it possible to print thin and highly flexible items, like plastic solar panels, electric textiles, and flexible gas sensors.

The contributions sought for this Special Issue are not limited to the above scope and are inclusive of all forms of 2D and 1D nanomaterials utilized towards sustainability.

We previously described GMC, a graphene-based nanomaterial obtained from carbon nanofibers (CNFs), to be biologically compatible and functional for therapeutic purposes. GMC can reduce triglycerides’ content in vitro and in vivo and has other potential bio-functional effects on systemic cells and the potential utility to be used in living systems. Here, immunoreactivity was evaluated by adding GMC in suspension at the biologically functional concentrations, ranging from 10 to 60 µg/mL, for one or several days, to cultured lymphocytes (T, B, NK), either in basal or under stimulating conditions, and monocytes that were derived under culture conditions to pro-inflammatory (GM-MØ) or anti-inflammatory (M-MØ) macrophages. All stirpes were obtained from human peripheral mononuclear cells (PBMCs) from anonymized healthy donors. The viability (necrosis, apoptosis) and immunological activity of each progeny was analyzed using either flow cytometry and/or other analytical determinations. A concentration of 10 to 60 µg/mL GMC did not affect lymphocytes’ viability, either in basal or active conditions, during one or more days of treatment. The viability and expression of the inflammatory interleukin IL-1β in the monocyte cell line THP-1 were not affected. Treatments with 10 or 20 µg/mL GMC on GM-MØ or M-MØ during or after their differentiation process promoted phagocytosis, but their viability and the release of the inflammatory marker activin A by GM-MØ were not affected. A concentration of 60 µg/mL GMC slightly increased macrophages’ death and activity in some culture conditions. The present work demonstrates that GMC is safe or has minimal immunological activity when used in suspension at low concentrations for pre-clinical or clinical settings. Its biocompatibility will depend on the dose, formulation or way of administration and opens up the possibility to consider GMC or other CNF-based biomaterials for innovative therapeutic strategies.
