Summary
Researchers developed eco-friendly neodymium selenide nanoparticles (Nd2Se3 NPs) using fungal reductase. These stable, water-dispersible nanoparticles show promise for bioimaging applications.
Area of Science:
- Biomaterials Science
- Nanotechnology
- Mycology
Background:
- Biomimetic synthesis offers sustainable routes for nanomaterial production.
- Neodymium selenide nanoparticles (Nd2Se3 NPs) have potential applications in bioimaging.
- Fungal enzymes present novel reducing agents for nanoparticle synthesis.
Purpose of the Study:
- To present a greener biomimetic fabrication of neodymium selenide nanoparticles (Nd2Se3 NPs).
- To utilize nitrate-dependent reductase from Fusarium oxysporum as a reducing agent.
- To functionalize Nd2Se3 NPs with a synthetic peptide for enhanced properties.
Main Methods:
- Biomimetic synthesis using fungal nitrate-dependent reductase.
- Peptide-assisted capping with (Glu-Cys)n-Gly for nanoparticle stabilization.
- Characterization via UV-Vis spectroscopy, fluorescence, dynamic light scattering (DLS), and X-ray diffraction (XRD).
Main Results:
- Fabrication of Nd2Se3 NPs with an average size of 18 ± 1 nm.
- DLS analysis showed hydrodynamic radii of 57 nm with a PDI of 0.440.
- The synthesized NPs exhibited water dispersibility and high emulsion stability (zeta potential -9.47 mV).
Conclusions:
- The biomimetic approach provides a sustainable method for Nd2Se3 NP synthesis.
- The peptide capping ensures good dispersibility and stability, crucial for biological applications.
