Aloe-inspired eco-friendly synthesis of Ag/ZnO heterostructures: boosting photocatalytic potential. Sci Rep 2024; 14:12711. [PMID: 38830908 PMCID: PMC11148178 DOI: 10.1038/s41598-024-61466-9] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 01/16/2024] [Accepted: 05/06/2024] [Indexed: 06/05/2024] Open
Abstract
The current research focuses on the development of Ag-ZnO heterostructures through a "bottom-up" approach involving the assembly and extraction of Aloe barbadensis Miller gel. These heterostructures composed of metals/semiconductor oxide display distinct and notable optical, electrical, magnetic, and chemical properties that are not found in single constituents and also exhibit photocatalytic applications. These synthesized heterostructures were characterized by XRD, FTIR, SEM, and UV-visible spectroscopy. The high peak intensity of the Ag/ZnO composite shows the high crystallinity. The presence of Ag-O, Zn-O, and O-H bonding is verified using FTIR analysis. SEM analysis indicated the formation of spherical shapes of Ag/ZnO heterostructures. The Zn, O, and Ag elements are further confirmed by EDX analysis. Ag-ZnO heterostructures exhibited excellent photocatalytic activity and stability against the degradation of tubantin red 8BL dye under visible light irradiation.

Non-covalent binding interaction of bioactive coumarin esculetin with calf thymus DNA and yeast transfer RNA: A detailed investigation to decipher the binding affinities, binding location, interacting forces and structural alterations at a molecular level. Int J Biol Macromol 2024; 257:128568. [PMID: 38061533 DOI: 10.1016/j.ijbiomac.2023.128568] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 11/07/2023] [Revised: 11/28/2023] [Accepted: 11/30/2023] [Indexed: 01/26/2024]
Abstract
Esculetin is a well-known coumarin derivative found abundantly in nature possessing an extensive array of pharmacological and therapeutic properties. Consequently, to comprehend its molecular recognition mechanism, our objective is to conduct a complete investigation of its interactions with the nucleic acid, specifically ct-DNA, and t-RNA, using spectroscopic and computational techniques. The intrinsic fluorescence of esculetin is quenched when it interacts with ct-DNA and t-RNA, and this occurs through a static quenching mechanism. The thermodynamic parameters demonstrated that the interaction is influenced by hydrogen bonding and weak van der Waals forces. CD and FT-IR results revealed no conformational changes in ct-DNA and t-RNA structure on binding with esculetin. Furthermore, competitive displacement assay with ethidium bromide, melting temperature, viscosity measurement, and potassium iodide quenching experiments, reflected that esculetin probably binds to the minor groove of ct-DNA. The molecular docking results provided further confirmation for the spectroscopic findings, including the binding location of esculetin and binding energies of esculetin complexes with ct-DNA and t-RNA. Molecular dynamics simulation studies demonstrated the conformational stability and flexibility of nucleic acids.

Complexation of turmeric and curcumin mediated silver nanoparticles with human serum albumin: Further investigation into the protein-corona formation, anti-bacterial effects and cell cytotoxicity studies. SPECTROCHIMICA ACTA. PART A, MOLECULAR AND BIOMOLECULAR SPECTROSCOPY 2023; 294:122540.

Abstract
Biosynthesized noble metal nanoparticles have been of recent interest due to their broad implications in the future biomedicinal field. We have synthesized silver nanoparticle using turmeric-extract and its major component curcumin as reducing and stabilizing agents. Further, we have investigated the protein-NPs interaction focusing the inspection of the role of biosynthesized AgNPs on any conformational changes of the protein, binding and thermodynamic parameters using spectroscopic techniques. Fluorescence quenching studies revealed that both CUR-AgNPs and TUR-AgNPs have moderate binding affinities (∼104 M-1) towards human serum albumin (HSA) and static quenching mechanism was involved in the binding. Estimated thermodynamic parameters indicate the involvement of hydrophobic forces in the binding processes. The surface charge potential of the biosynthesized AgNPs became more negative upon complexation with HSA as observed from Zeta potential measurements. Antibacterial efficacies of the biosynthesized AgNPs were evaluated against Escherichia coli (gram-negative) and Enterococcus faecalis (gram-positive) bacterial strains. The AgNPs were found to destroy the cancer (HeLa) cell lines in vitro. The overall findings of our study successfully outline the detailed insight of the protein corona formation by biocompatible AgNPs and their biological applications concerning the future scope in the biomedicinal field.

Abstract
Abstract
This work investigates the green synthesis of silver nanoparticles (AgNPs) utilizing the aqueous leaf extract of Ocimum sanctum L. A change in colour to dark brown from yellow and an absorption maximum at 460 nm provided evidence for the synthesis of AgNPs. Several reaction conditions namely leaf extract volume, AgNO3 concentration and duration of incubation were optimized. Maximum synthesis of AgNPs could be achieved with 1 ml of 5% aqueous leaf extract, 1 mM AgNO3 and 2.5 h incubation period. DPPH (2, 2—diphenyl − 1 - picrylhydrazyl) assay revealed that AgNPs are better than the leaf extract in terms of antioxidant potential. These results strongly recommend the application of green-synthesized AgNPs as effective antioxidants against oxidative stresses associated with degenerative diseases. Characterization of AgNPs were then carried out using certain methods namely as x-ray diffraction (XRD) measurement, Fourier transform infrared spectroscopy (FTIR) and scanning electron microscopy (SEM). XRD study confirmed the synthesis of face-centered cubic-shaped AgNPs that are of crystalline nature. The mean particle size of the synthesized AgNPs computed employing the Debye–Scherrer formula, was 22 nm. FTIR study demonstrated that the AgNPs consisted of certain functional groups of O. sanctum which might have helped in reducing AgNO3 and capping AgNPs. SEM images showed the synthesis of AgNPs of various shapes viz. globular, cubical and flaky. The scattered AgNPs were found to have a size close to 20 nm, which roughly matches with the XRD analysis of the current study.
