Nanoparticles Synthesis by Plants

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.
• Possible variations depending on the type of plant material.
