Interactions of newly synthesized platinum nanoparticles with ICR-191 and their potential application.

ABSTRACT: One of the greatest challenges of modern medicine is to find cheaper and easier ways to produce transporters for biologically active substances, which will provide selective and efficient drug delivery to the target cells, while causing low toxicity towards healthy cells. Currently, metal-based nanoparticles are considered a successful and viable solution to this problem. In this work, we propose the use of novel synthesis method of platinum nanoparticles (PtNPs) connected with their precise biophysical characterization and assessment of their potential toxicity. To work as an efficient nanodelivery platform, nanoparticles should interact with the desired active compounds spontaneously and non-covalently. We investigated possible direct interactions of PtNPs with ICR-191, a model acridine mutagen with well-established biophysical properties and mutagenic activity, by Dynamic Light Scattering, fluorescence spectroscopy, and Isothermal Titration Calorimetry. Moreover, to determine the biological activity of ICR-191-PtNPs aggregates, we employed Ames mutagenicity test, eukaryotic cell line analysis and toxicity test against the model organism Caenorhabditis elegans. PtNPs' interesting physicochemical properties associated to the lack of toxicity in a tested range of concentrations, as well as their ability to modulate ICR-191 biological activity, suggest that these particles successfully work as potential delivery platforms for different biologically active substances.

Project description:Developing sustainable and eco-friendly methods for nanoparticle (NP) production in an era of environmental consciousness is crucial. This study introduces a novel approach to synthesizing silver (Ag) NPs using Citrus paradisi leaves extract (CPLE) as a green precursor at optimum conditions of the AgNO3 (2 mM) with CPLE in 1:3 ratio, at pH 14 and 80 °C temperature for reaction time of 4 h. The CP@AgNPs were formed and stabilized by Naringen, a major Citrus paradisi component. CP@AgNPs were thoroughly characterized through ultraviolet-visible (UV-vis) and Fourier transform infrared (FTIR) spectroscopy, X-ray diffraction (XRD) analysis, and field emission scanning electron microscopy (FE-SEM) imaging techniques. CP@AgNPs demonstrated SPR peak at 450 nm, face cubic crystal structure, the average size of 8 nm, rod-shaped particle adsorbed on quasi-spherical shaped agglomerated NPs, significantly impacting both environmental and biomedical fields. In the catalytic degradation experiment, an application for environment pollutant reducer, CP@AgNPs, achieved an impressive 85% degradation efficiency of the methyl orange (MO) dye, showcasing their potential as a sustainable solution for wastewater treatment. Additionally, CP@AgNPs exhibited potent anti-biofilm properties, with half maximal inhibitory concentration (IC50) values of 0.13 and 0.12 mg/ml against Escherichia coli (E. coli) and Staphylococcus aureus (S. aureus), respectively, indicating their promise in addressing biofilm-related issues in healthcare and industrial settings. CP@AgNPs also displayed exceptional antioxidant potential with IC50 values of 2.02, 0.07, and 0.035 mg/ml for CPLE, CP@AgNPs, and ascorbic acid, respectively, in scavenging DPPH radical, suggesting their utility in biomedical applications for mitigating oxidative stress. Notably, the bio-activity results of CP@AgNPs surpassed those of CP leaf extract, highlighting the enhanced properties achieved through this green synthesis approach. This study provides a sustainable and environmental remediation to biomedical science.
