ABSTRACT
Background: The preparation of silver nanoparticles often involves some tedious steps and extra reducing agents. PDMAEMA and β-CD can act as the reducing and stabilizing agents for the preparation of silver nanoparticles without any external reducing agent.Methods: β-Cyclodextrin-g-Poly (2-(dimethylamino) ethylmethacrylate) as the stabilizer and reductant to prepare colloid silver nanoparticles in situ. Such an approach greatly simplified the preparation and purification of silver nanoparticles.Results: The graft yield of β-CD-g-PDMAEMA increased with the increase of amount of DMAEMA.Ag nanoparticles was obtained under neutral or slightly alkaline environment.The intensity of surface plasmon resonance peak of Ag nanoparticles increased as the concentration of β-CD-g-PDMAEM and silver nitrate increased. In addition, the Ag nanoparticles were in the form of spherical particles observed by transmission electron microscopy (TEM). The FTIR spectrum of nanocomposite showed that coordination existed between the silver nanoparticles and tertiary amino groups of PDMAEMA segments.Conclusion: Silver nanoparticles were successfully prepared by in situ synthetic method, using β-CD-g- PDMAEMA as both reductant and stabilizer. It can be envisioned that the theroresponsive silver nanocomposite could find applications in biomedical feld.
