Bagasse to Bio-nanotech: Eco-friendly Synthesis of Silver Nanoparticles from Saccharum officinarum with Promising Anti-aging Potential | Chapter 3 | Chemical and Materials Sciences: Research Findings Vol. 6

 

Background: Nanotechnology, a rapidly evolving field, deals with the manipulation of materials at the atomic and molecular levels within the size range of 1 to 100 nanometres. Nanotechnology finds applications across numerous scientific disciplines, including physics, chemistry, biology, and materials science. Saccharum officinarum is a lignocellulose material rich in cellulose and fibre, widely used in paper, packaging, textile, and construction industries.

 

Aim: The present study aims to synthesise eco-friendly and cost-effective silver nanoparticles (AgNPs) using the aqueous extract of Saccharum officinarum stem and to evaluate their potential anti-ageing activity for cosmetic and biomedical applications.

 

Methodology: This experimental study focuses on the green synthesis, characterisation, and biological evaluation of silver nanoparticles using plant-based reducing agents derived from Saccharum officinarum stem extract. The study was conducted in the PG and Research Department of Chemistry, Holy Cross College (Autonomous), Trichy. The aqueous extract of Saccharum officinarum stem (bagasse) was prepared and subjected to phytochemical screening, which confirmed the presence of alkaloids, tannins, flavonoids, anthraquinones, terpenoids, polyphenols, and glycosides. These biomolecules served as natural reducing and stabilising agents during the synthesis of silver nanoparticles. The formation of AgNPs was visually indicated by a colour change from pale yellow to dark brown. Characterisation was carried out using UV–Visible Spectroscopy, Scanning Electron Microscopy (SEM), and Energy Dispersive X-ray Spectroscopy (EDAX) to confirm nanoparticle formation, morphology, and elemental composition.

 

Results: The UV–Visible spectrum showed a distinct absorption peak at 477 nm, confirming the surface plasmon resonance of silver nanoparticles. SEM analysis revealed well-dispersed, uniformly distributed nanoparticles with smooth morphology, while EDAX confirmed the elemental purity of silver. The synthesised AgNPs exhibited notable anti-ageing potential, likely due to the synergistic antioxidant effects of phytochemicals present in the Saccharum officinarum extract.

 

Conclusion: The study successfully demonstrates a sustainable and green approach for synthesising silver nanoparticles using Saccharum officinarum stem extract. The biosynthesised AgNPs exhibit promising anti-ageing properties, making them suitable for incorporation into cosmetic formulations such as anti-ageing creams and skin treatments. This eco-friendly method aligns with green chemistry principles and holds potential for future applications in nanomedicine and cosmeceutical industries.
