ACS OMEGA 2023; 8:48775-48786. [PMID: 38162781 PMCID: PMC10753701 DOI: 10.1021/acsomega.3c05743] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Grants] [Track Full Text] [Download PDF] [Figures] [Subscribe] [Scholar Register] [Received: 08/05/2023] [Revised: 10/10/2023] [Accepted: 10/17/2023] [Indexed: 01/03/2024]
Abstract
A simple, facile, moist-heating (e.g., autoclave), one-step procedure for EGCG-mediated biosynthesis of narrow-size magnetic iron oxide (α-Fe2O3) nanoparticles (EGCG-MINPs) was developed. The influence of pH of the reaction mixture over the size distribution of as-synthesized EGCG-MINPs was investigated systematically by employing UV-visible (UV-vis) spectroscopy and dynamic light scattering (DLS)-based hydrodynamic size, surface charge (zeta-potential), and polydispersity index (PDI). The FE-SEM, TEM, and XRD characterizations revealed that the EGCG-MINPs synthesized at pH 5.0 were in the size range of 6.20-16.7 nm and possess well-crystalline hexagonal shaped nanostructures of hematite (α-Fe2O3) crystal phase. The role of EGCG in Fe3+ ion reduction and EGCG-MINP formation was confirmed by FTIR analysis. The VSM analysis has revealed that EGCG-MINPs were highly magnetic nanostructures with the hysteretic feature of saturation magnetization (Ms), remanent magnetization (Mr), and coercivity (Hc) as 33.64 emu/g, 12.18 emu/g, and 0.33 Oe, respectively. Besides, significant (p < 0.001) dose-dependent (250-1000 μg/mL) antibacterial and antibiofilm activities against the NDM-1-producing Gram-negative Escherichia coli (AK-33), Klebsiella pneumoniae (AK-65), Pseudomonas aeruginosa (AK-66), and Shigella boydii (AK-67) bacterial isolates warranted the as-synthesized EGCG-MINPs as a promising alternative for clinical management of chronic bacterial infections in biomedical settings. In addition, molecular docking experiments revealed that compared to free Fe3+ and EGCG alone, the EGCG-MINPs or Fe-EGCG complex possess significantly high binding affinity toward HSA and hence can be considered as promising biocompatible nanodrug carriers in in vivo drug delivery systems.

Abstract
Inflammatory bowel disease (IBD) is a chronic recurrent inflammatory disease of the digestive tract that causes pain and weight loss and also increases the risk of colon cancer. Inspired by the benefits of plant-derived nanovesicles and aloe, we herein report aloe-derived nanovesicles, including aloe vera-derived nanovesicles (VNVs), aloe arborescens-derived nanovesicles (ANVs), and aloe saponaria-derived nanovesicles (SNVs) and evaluate their therapeutic potential and molecular mechanisms in a dextran sulfate sodium (DSS)-induced acute experimental colitis mouse model. Aloe-derived nanovesicles not only facilitate markedly reduced DSS-induced acute colonic inflammation, but also enable the restoration of tight junction (TJ) and adherent junction (AJ) proteins to prevent gut permeability in DSS-induced acute colonic injury. These therapeutic effects are ascribed to the anti-inflammatory and anti-oxidant effects of aloe-derived nanovesicles. Therefore, aloe-derived nanovesicles are a safe treatment option for IBD.

Abstract
Cancer and COVID-19 have been deemed as world health concerns due to the millions of lives that they have claimed over the years. Extensive efforts have been made to develop sophisticated, site-specific, and safe strategies that can effectively diagnose, prevent, manage, and treat these diseases. These strategies involve the implementation of metal nanoparticles and metal oxides such as gold, silver, iron oxide, titanium oxide, zinc oxide, and copper oxide, formulated through nanotechnology as alternative anticancer or antiviral therapeutics or drug delivery systems. This review provides a perspective on metal nanoparticles and their potential application in cancer and COVID-19 treatments. The data of published studies were critically analysed to expose the potential therapeutic relevance of green synthesized metal nanoparticles in cancer and COVID-19. Although various research reports highlight the great potential of metal and metal oxide nanoparticles as alternative nanotherapeutics, issues of nanotoxicity, complex methods of preparation, biodegradability, and clearance are lingering challenges for the successful clinical application of the NPs. Thus, future innovations include fabricating metal nanoparticles with eco-friendly materials, tailor making them with optimal therapeutics for specific disease targeting, and in vitro and in vivo evaluation of safety, therapeutic efficiency, pharmacokinetics, and biodistribution.

Marine Macroalgae Display Bioreductant Efficacy for Fabricating Metallic Nanoparticles: Intra/Extracellular Mechanism and Potential Biomedical Applications. Bioinorg Chem Appl 2021; 2021:5985377.

Abstract
The application of hazardous chemicals during nanoparticle (NP) synthesis has raised alarming concerns pertaining to their biocompatibility and equally to the environmental harmlessness. In the recent decade, nanotechnological research has made a gigantic shift in order to include the natural resources to produce biogenic NPs. Within this approach, researchers have utilized marine resources such as macroalgae and microalgae, land plants, bacteria, fungi, yeast, actinomycetes, and viruses to synthesize NPs. Marine macroalgae (brown, red, and green) are rich in polysaccharides including alginates, fucose-containing sulfated polysaccharides (FCSPs), galactans, agars or carrageenans, semicrystalline cellulose, ulvans, and hemicelluloses. Phytochemicals are abundant in phenols, tannins, alkaloids, terpenoids, and vitamins. However, microorganisms have an abundance of active compounds ranging from sugar molecules, enzymes, canonical membrane proteins, reductase enzymes (NADH and NADPH), membrane proteins to many more. The prime reason for using the aforesaid entities in the metallic NPs synthesis is based on their intrinsic properties to act as bioreductants, having the capability to reduce and cap the metal ions into stabilized NPs. Several green NPs have been verified for their biocompatibility in human cells. Bioactive constituents from the above resources have been found on the green metallic NPs, which has demonstrated their efficacies as prospective antibiotics and anti-cancer agents against a range of human pathogens and cancer cells. Moreover, these NPs can be characterized for the size, shapes, functional groups, surface properties, porosity, hydrodynamic stability, and surface charge using different characterization techniques. The novelty and originality of this review is that we provide recent research compilations on green synthesis of NPs by marine macroalgae and other biological sources (plant, bacteria, fungi, actinomycetes, yeast, and virus). Besides, we elaborated on the detailed intra- and extracellular mechanisms of NPs synthesis by marine macroalgae. The application of green NPs as anti-bacterial, anti-cancer, and popular methods of NPs characterization techniques has also been critically reviewed.
