研究目的
Investigating the green synthesis of silver nanoparticles using the aqueous stem extract of Ceriops tagal and evaluating its medicinal potency enhancement.
研究成果
The study successfully demonstrated the rapid biosynthesis of silver nanoparticles from Ceriops tagal stem extract. The process is eco-friendly, easily scalable, and economically viable. The nanoparticles showed potential for various applications, including health management. Further studies are recommended to optimize the synthesis process and evaluate the safety of the nanoparticles.
研究不足
The study reports the synthesis of poly-dispersed nanoparticles. Further studies are needed to obtain monodispersed nanoparticles and to separate them based on shape and size. The compounds responsible for reduction and capping need to be properly identified and separated. Long-term toxicity, mutagenicity, and carcinogenicity studies are also required.
1：Experimental Design and Method Selection:
The study involved the biosynthesis of silver nanoparticles using the aqueous stem extract of Ceriops tagal as a bio-reducing agent. The reduction of metal ions was monitored using UV-Visible absorption spectroscopy, TEM, EDS, and XRD. FTIR was used to record changes in functional groups before and after bio-reduction.
2：Sample Selection and Data Sources:
The stem of Ceriops tagal was collected from Gorai creek, Mumbai, India. The aqueous stem extract was prepared and used for the synthesis of silver nanoparticles.
3：List of Experimental Equipment and Materials:
UV-1650CP Schimadzu spectrophotometer, TEM (Tecnai 12 Cryo, FEI, Eindhoven, The Netherlands), XRD (Schimadzu XRD 7000 diffractometer), FTIR (Perkin Elmer) Frontier spectrophotometer.
4：Experimental Procedures and Operational Workflow:
The synthesis was initiated by adding CTSE to aqueous AgNO3 solution. The reaction was monitored over time, and the effects of temperature and metal salt concentration were studied. The synthesized nanoparticles were characterized using various spectroscopic and microscopic techniques.
5：Data Analysis Methods:
The crystallite size of the nanoparticles was estimated from the Debye–Scherrer formula. The functional groups involved in capping and stabilization were identified using FTIR.
