“…AgNPs have been embedded in some optical transparent materials such as functionalized silicate sol gel network film (Maduraiveer and Ramaraj, 2013), ZnO, Al 2 O 3 , SiN x , and SiO x substrates to produce the optical sensors for analytes detection (Schmidl et al, 2015). Reports are currently available for embedding of AgNPs within microcrystalline cellulose (Vivekanandhan et al 2012), TEMPO-mediated oxidized bacterial cellulose (Feng et al 2014), and bacterial cellulose (Maneerung et al 2008, Fortunati et al 2012 for biomedical applications such as antimicrobial wound dressings.…”

“…In this regard, silver (Ag) is an ideal candidate for an experimental study of the dewetting kinetics since it is inert in its metallic form; thus its topological characteristics can be separated by chemical properties, providing a simplified system to study. Recently, solid-state dewetting in Ag thin films has received renewed attention in relation to its potential interest for example in plasmonics, where the morphology and characteristics of surface nanostructures are strongly related to plasmon response and thus to sensitivity of devices [11,12]. As Ag becomes biologically active when ionized, which typically occurs upon exposure to an aqueous media [13], applications of Ag dewetting in biomedicine involve the realization of structures with antimicrobial activity where the control over morphology is important in regulating the balance between cytotoxicity and antimicrobial action [14,15].…”

Solid-state dewetting phenomenon in silver thin films offers a straightforward method to obtain structures having controlled shape or size-this latter in principle spanning several orders of magnitudes-with potentially strong interest in many applications involving high-tech industry and biomedicine. In this work nanostructured silver is deposited by pulsed electron ablation technique and its surface modified upon thermal treatments in air at increasing temperatures. Surface chemistry and morphology are then monitored simultaneously by X-ray photoemission spectroscopy and atomic force microscopy; in particular, the power spectral density of surface heights is used to analyze the alteration of morphology induced by annealing. It is shown that this approach adds a level of information about the dewetting process since it allows to separate between long-and short-range surface behavior and to retrieve statistical quantities relevant to a description of the features in view of applications. Our results are presented in the framework of a multidisciplinary approach, advantages and limits of which are deepened and discussed.

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.
