Special Issue Information

Dear Colleagues,

In the last ten years, nanomaterials have been used in many fields, such as medicine, diagnostics, drug release, food additives, agriculture, and the environment. Biomolecule nanomaterials synthesized from bacteria or other microorganisms from algae and plants have been used in many of these fields. In this Special Issue, we want to address all the aspects of bio-nano molecules from production to their use in the environment. Cutting-edge bionanomaterials have novel properties, and therefore, we solicit papers that evidence the novel characteristics and peculiarities of actions of these nanomaterials and how they can be applied. Materials like chitosan, nanocellulose and others have the capacity to adapt to many human activities and can contribute to the human and environmental well-being.

Disordered reactive oxygen/nitrogen species are a common occurrence in various diseases, which usually cause cellular oxidative damage and inflammation. Despite the wide range of applications for biomimetic nanoparticles with antioxidant or anti-inflammatory properties, designs that seamlessly integrate these two abilities with a synergistic effect in a simple manner are seldom reported. In this study, we developed a novel PEI-Mn composite nanoparticle (PM NP) using a chelation method, and the curcumin was loaded onto PM NPs via metal–phenol coordination to form PEI-Mn@curcumin nanoparticles (PMC NPs). PMC NPs possessed excellent dispersibility and cytocompatibility, was engineered to serve as an effective nanozyme, and exhibited specific SOD-like and CAT-like activities. In addition, the incorporation of curcumin granted PMC NPs the ability to effectively suppress the expression of inflammatory cytokines in microglia induced by LPS. As curcumin also has antioxidant properties, it further amplified the synergistic efficiency of ROS scavenging. Significantly, PMC NPs effectively scavenged ROS triggered by H2O2 in SIM-A9 microglia cells and Neuro-2a cells. PMC NPs also considerably mitigated DNA and lipid oxidation in Neuro-2a cells and demonstrated an increase in cell viability under various H2O2 concentrations. These properties suggest that PMC NPs have significant potential in addressing excessive ROS and inflammation related to neural diseases. Full article

Abstract: Identifying an optimal, non-toxic, and easily available sensitizer for dye-sensitized solar cell (DSSC) application remains a challenging task. Previously, a new class of sensitizers based on bio-nano hybrids has been proposed. These systems composed of natural cyanidin dyes interacting with silver nanoclusters (NCs) have demonstrated enhanced opto-electronic and photovoltaic properties. In this study, we employ Density Functional Theory (DFT) and its time-dependent counterpart (TDDFT) to explore the possibility of coinage metal doping of silver nanocluster within cyanidin-NC hybrid. Specifically, we investigate the influence of coinage metal atoms (Au and Cu) on the properties of the smallest cyanidin-NC system, cyanidin-Ag3. Our findings suggest that cyanidin-Ag2Au emerges as the most promising candidate with improved light harvesting efficiency and strong coupling to the TiO2 surface. These theoretical predictions suggest the viability of replacing large silver NCs with smaller composed of coinage metal atoms, presenting new avenues for utilizing bio-nano hybrids for DSSC application.
