“…In the majority of literature studies, silver ion-exchanged glasses have been investigated concerning characteristics such as diffusion kinetics, glass network structural properties [10], down-shifting properties [11,12], mechanical reinforcement [13], electrical conductivity [14], coloring [15,16], refractive index [17][18][19], surface plasmon resonance (SPR) absorption characteristics [20][21][22] and antimicrobial efficacy [23,24]. To effectively employ silver ion-exchanged silicate glasses in numerous of these applications areas, it is essential to understand the behavior of silver as it penetrates the glass matrix and undergoes potential subsequent treatments, such as thermal annealing.…”

The effects of ion exchange time and temperature on the optical properties and plasmonic response of silver ion exchanged soda–lime silicate glass were investigated using scanning electron microscopy (SEM) in energy dispersive spectrometry (EDS) configuration, m-lines spectroscopy, photoluminescence spectroscopy, and UV–visible absorption spectroscopy. SEM analyses in EDS mode provided profiles of silver oxide molar concentration. These profiles were directly correlated to the silver diffusion coefficient using an adjustment procedure. The effective indices of ion exchanged glasses measured by the standard prism coupling technique (m-lines) allowed access to refractive index distributions in ion exchange regions. These ion-exchanged glasses underwent evaluation to determine their potential suitability for use in multimode planar systems.The photoluminescence results acquired after ion exchange demonstrated that the creation of Ag0 atoms from Ag+ ions was responsible for the decline and quenching of photoluminescence intensity at ion exchange times and temperatures increase. Silver nanoparticles were generated in the samples subjected to ion exchange at 480°C without the need for post-exchange treatments. The emergence of the plasmon resonance (SPR) band around 427 nm in the optical absorption spectra confirmed the formation of Ag nanoparticles in annealed glasses. Estimates of the UV-visible absorption spectra indicated an average size of silver nanoparticles ranging from 1.8 to 2.4 nm.

A wound can be defined as the disruption of the normal integrity of the body. the management of wounds usually ends up with scars that can cause functional harm and emotional and social distress. All these urge the need for new approaches for faster healing by anti-infective effect, moisturizing, stimulating the healing mechanisms, speeding up the wound closure and dropping scar formation, this paper aimed at evaluating the wound healing effect of cellulose nano encapsulated Elaeis guineensis silver nanoparticle. The plants were collected and formally identified at the national herbarium. After drying and grounding, the aqueous decoction was prepared. The phytochemical screening was performed on the crude extract. From the prepared extracts, the nanoparticle was prepared according to the previously described protocol. The prepared nanoparticles were encapsulated with cellulose. The cellule nanocapsules of Elaeis guineensis were tested for the in vitro anti-inflammatory effect using the heated BSA denaturation test. The acute dermal toxicity of the cellulose nano-encapsulated Elaeis guineesis silver nanoparticle was performed according to guideline 402 of the OEDC. The wound healing test was performed on rat dorsal open wounds using a series of doses of the prepared cellulose nano-encapsulated Elaeis guineesis silver nanoparticle (CNC-EgNP). The extract was revealed to contain alkaloids and polyphenols. Heterosids were not detected. The nanoparticle was successfully prepared, and nano encapsulated with cellulose was successfully done when referring to the absorption feature of the mixture. The results showed that CNC-EgNP protects the protein from heat-denaturation with up to 94.9% with 25µg/ml. Compared to diclofenac, used here as a reference, at 200 µg/ml, the CNC-EgNP seems more effective with 54,2% and 98,65% respectively. No sign of toxicity was observed from the toxicity testing. The CNC-EgNP 200mg/kg BW has the best effect as it annuls the wound after 13 days. CNC-EgNP 100 and 400 mg/kg BW and crude extracts had a statistically similar effect. All annul the wound on day 15. Up to that period, the trolamine, used here as a positive control, failed to bring to 0 the area of the wound. The results highlight the potential of the cellulose nanocapsule of Elaeis guineensis silver nanoparticle as an alternative for wound management.

“…Furthermore, due to the appearance of d-shell in silver material there are several ways in which it can be found in nature [1], for instance: AgO, Ag2O, Ag3O and Ag2O3. In particular, because the applications have been treated as AgO and Ag2O, or as cathodic materials in Zn-silver oxide batteries [2][3][4][5][6], silver alloys as optical data storage [7], or in medicine [8], Ag nanoparticles result interesting like a antimicrobial agents [9]. A form of silver that is also worth mentioning is clatharate-type silver oxide, which has superconductor properties [10].…”

Chemical bath deposition technique at room temperature proved to be efficient in synthetizing elemental silver clusters on Silver (I, II, III) oxide clathrate films, Ag0/Ag708HCO3.The set of samples was prepared for 30, 60, 90 and 120 minutes.All films exhibited a yellowish-brown color and presented good adherence to the corning glass substrate.The direct band gaps values were 3.77 to 3.82 eV.A cubic crystallographic structure was determined with the usage of TEM; while SEM was used for the observation of their morphology which showed a very homogenous flat background with a distribution of metallic silver clusters with irregular shape was growing.
