What is Biosynthesis of Metal Nanoparticles?

Biosynthesis of metal nanoparticles uses plant extracts as reducing and stabilizing agents for eco-friendly synthesis of ZnO, Ag, and CuO nanoparticles with applications in anticancer, antibacterial, and dye removal activities.

This approach employs leaf extracts from plants like Mangifera indica and Garcinia mangostana to produce ZnO and CuO nanoparticles, optimizing parameters for size and stability (Rajeshkumar et al., 2018; Chan et al., 2022). Studies evaluate their antioxidant properties in A549 lung cancer cells and antibacterial effects (Barzinjy et al., 2019; Jaithon et al., 2024). Over 10 key papers since 2018 document methods and characterizations, with Rajeshkumar et al. (2018) cited 277 times.

Key Challenges

Why It Matters

Biosynthesized ZnO nanoparticles from Mangifera indica leaves show cytotoxic effects on A549 lung cancer cells and antioxidant activity, enabling green nanomedicine alternatives to chemical synthesis (Rajeshkumar et al., 2018). CuO nanostructures from Garcinia mangostana extracts, tuned by calcination temperature, advance optical and structural applications in sensors and photocatalysis (Chan et al., 2022). ZnO nanoparticles from mangosteen peel inhibit Xanthomonas oryzae, promoting rice growth and reducing pesticide use in agriculture (Jaithon et al., 2024). These methods support sustainable dye removal using palm leaf hydrochar (Hammud et al., 2023).

Key Research Challenges

Size and Morphology Control

Achieving uniform nanoparticle size requires precise optimization of extract concentration, pH, and calcination temperature, as variations lead to polydispersity (Chan et al., 2022). Plant extract variability affects reproducibility across batches (Barzinjy et al., 2019). Rajeshkumar et al. (2018) highlight challenges in scaling stable ZnO nanoparticles for biomedical use.

Stability and Aggregation Prevention

Biosynthesized nanoparticles aggregate over time without robust capping agents, reducing long-term efficacy (Ermawati et al., 2022). Hydrogels with nanosilver from turmeric show stability issues under storage (Ermawati et al., 2022). Yanti and Maryanti (2021) note low-temperature calcination limits stability in ZnO from Sapindus rarak.

Bioactivity Mechanism Elucidation

Linking nanoparticle structure to anticancer or antibacterial activity demands advanced assays, but mechanisms remain unclear (Rajeshkumar et al., 2018). Antioxidant tests in A549 cells show promise, yet dose-response correlations are inconsistent (Barzinjy et al., 2019). Agricultural applications like rice growth promotion need field validation (Jaithon et al., 2024).
