Study Notes
Nanoparticles Synthesis by Plants
- Plant-based methods for producing nanoparticles are environmentally friendly, using low temperature and energy, and avoiding toxic chemicals.
- Plant metabolites (compounds) act as reducing and stabilizing agents in nanoparticle synthesis.
- Different plant extracts and parts can produce nanoparticles of varying shapes and sizes.
- Reduction of metal ions to metal atoms is a key step.
- Plant extracts are used to reduce and stabilize metal ions, forming nanoparticles.
- Nanoparticles are characterized by X-ray diffraction (XRD), Fourier transform infrared spectroscopy (FTIR), UV-Vis spectroscopy, transmission electron microscopy (TEM), and scanning electron microscopy (SEM).
Synthesis of Nanoparticles from Plants
- Plant compounds like phenolic acids, flavonoids, and naphthalenones are used for reduction and stabilization.
- Xanthones, phloroglucinols, and naphthalenones contribute to the stabilization of nanoparticles.
- Nanoparticle size and shape are determined by plant metabolites.
- Plant extracts, reducing agents, and stabilizing agents can control NP synthesis.
- Some plants used include Aloe vera, Mangifera indica, and Eucalyptus macrocarpa.
- Silver nanoparticles, produced from silver ions, are a common example.
Characterization of Nanoparticles
- Techniques like XRD, FTIR, UV-Vis, TEM, and SEM are used to study nanoparticle properties.
- The size and shape of nanoparticles (e.g., spherical, hexagonal) are analyzed.
- Properties like size and shape are important factors determining application and functionality.
Green Synthesis of Nanoparticles
- Plant-based NP synthesis is considered an environmentally friendly method compared to traditional techniques using non-biological approaches.
- Plant metabolites, such as terpenoids, flavonoids, or tryptophan and tyrosine, aid in this process.
- The synthesis utilizes easily available plant materials for reduction and stabilization.
- Nanoparticles are characterized by various techniques (XRD, FTIR, etc.) to determine their formation.
Advantages of Plant-based NP Synthesis
- Environmentally friendly, using low energy, low temperature, and avoiding toxic chemistry.
- Easily available, inexpensive plant-based and natural resources.
- Fast and cost-effective nanoparticle synthesis.
Disadvantages of Plant-based NP Synthesis
- Some processes might require careful control of reaction parameters.
- There can be fluctuations in product yield when plant extracts are used.
