Dynamic light scattering is a method that depends on the interaction of with particles. This can be used for measurements narrow particle size distributions especially in range 2–500 nm. Sample polydispersity distort results, and we could not see real populations particles because big presented sample screen smaller ones. Although theory mathematical basics DLS technique are already well known, little has been done to determine its limits experimentally. The distribution artificially...
We describe herein the significance of a sodium citrate and tannic acid mixture in synthesis spherical silver nanoparticles (AgNPs). Monodisperse AgNPs were synthesized via reduction nitrate using two chemical agents: acid. The shape, size distribution particles determined by UV-Vis spectroscopy, dynamic light scattering (DLS) scanning transmission electron microscopy (STEM). Special attention is given to understanding experimentally confirming exact role reagents (sodium present reaction...
Silver nanoparticles (AgNPs) have been shown to promote wound healing and exhibit antimicrobial properties against a broad range of bacteria. In our previous study, we prepared tannic acid (TA)-modified AgNPs showing good toxicological profile immunomodulatory useful for potential dermal applications.In this in vitro scratch assay, tests, modified lymph node assay as well mouse splint model were used access the TA-modified unmodified AgNPs.TA-modified but not exhibited effective...
(1) Background: Tannic acid is a plant-derived polyphenol showing antiviral activity mainly because of an interference with the viral adsorption. In this work, we tested whether modification silver nanoparticles tannic (TA-AgNPs) can provide microbicide additional adjuvant properties to treat genital herpes infection. (2) Methods: The mouse model vaginal simplex virus 2 (HSV-2) infection was used test immune responses after treatment primary TA-AgNPs, and later, re-challenge virus. (3)...
In restorative dentistry, there are no standardized in vitro accelerated aging methods to evaluate the long-term stability of dental composites. Current research aimed at extending clinical success restorations emphasizes need for post-aging evaluation. This study represents final stage assessing three selected protocols that utilize a 0.1 M sodium hydroxide solution as primary agent accelerate degradation processes. Twelve resin-based composites, categorized into five types, were evaluated...
In this paper, we discuss the influence of ligand type present on surface silver nanoparticles (AgNPs) its affinity to virus and virucidal activity against herpes simplex 2 (HSV-2). We selected four different ligands, which potentially exhibit HSV-2 used them for functionalization AgNPs: i) sodium citrate: ii) tannic acid; iii) 1-mercaptoundecane-1-sulfonate (MUS); iv) poly(ethylene glycol) (PEG). The antiviral was performed by in vitro Vero cell culture. Anti- inflammatory measurement NF-κB...
(1) Background: Lactoferrin has been recognized as a potent inhibitor of human herpetic viruses, such herpes simplex type 1 (HSV-1) and 2 (HSV-2). In this work, we tested if silver gold nanoparticles modified with lactoferrin (LF-Ag/AuNPs) can become novel microbicides additional adjuvant properties to treat genital infection. (2) Methods: The antiviral cytotoxic activities LF-Ag/AuNPs were in skin HaCaT vaginal VK-2-E6/E7 keratinocytes. Viral titers immune responses after treatment murine...
Polyphenols possess antioxidant, anti-inflammatory and antimicrobial properties have been used in the treatment of skin wounds burns. We previously showed that tannic acid-modified AgNPs sized >26 nm promote wound healing, while 13 can elicit strong local inflammatory response. In this study, we tested bimetallic Au@AgNPs 30 modified with selected flavonoid non-flavonoid compounds for healing applications.Bimetallic were obtained by growing an Ag layer on AuNPs further polyphenols. After...
Transition metal oxides have garnered attention for the methanol electro‐oxidation reaction owing to their easy availability, high catalytic applicability, and multiple oxidation capabilities. Bimetal‐based catalysts further enhance performance of reaction. In this context, a chrysanthemum‐flower‐like MoO 2 /WO 3 is synthesized through solvothermal annealing strategy. The morphology attests rough surface pores in catalyst, augmenting its area reactions enhancing applicability....
Silver nanoparticles (AgNPs) are promising new antimicrobial agents against a wide range of skin and mucosal pathogens. However, their interaction with the immune system is currently not fully understood. Dendritic cells (DCs) crucial during development T cell-specific responses bacterial viral We have previously shown that tannic acid-modified silver (TA-AgNPs) consist microbicide HSV-2. The aim this study was to compare ability TA-AgNPs or TA-AuNPs similar sizes (TA-Ag/AuNPs) induce DCs...
The clinical performance of a dental restoration is strongly influenced by the complex and dynamically-changing oral environment; however, no standard procedure exists to evaluate this lifetime. This research provides an in-depth analysis effect different aging procedures on flexural strength (FS), diametral tensile (DTS) hardness (HV) selected materials (Resin F, Flow-Art Arkon). Material structure was evaluated scanning electron microscopy. It found that each protocol had some influence...
(1) Background: Epigallocatechin gallate (EGCG) has been recognized as a flavonoid showing antiviral activity against various types of DNA and RNA viruses. In this work, we tested if EGCG-modified silver nanoparticles (EGCG-AgNPs) can become novel microbicides with additional adjuvant properties to treat herpes infections. (2) Methods: The anti-HSV cytotoxic activities EGCG-AgNPs were in human HaCaT VK-2-E6/E7 keratinocytes. HSV-1/2 titers immune responses after treatment murine models...
In the present paper we describe a phase transfer of aqueous synthesized gold nanoparticles (AuNPs) from water to toluene using secondary amines: dioctylamine, didodecylamine, and dioctadecylamine. The effect hydrocarbon chain length amount amines on efficiency were investigated in case (NPs) with three different sizes: 5, 9, 13 nm. Aqueous colloids precisely characterized before process UV-vis spectroscopy, dynamic light scattering (DLS), small-angle X-ray (SAXS), transmission electron...
Introduction: Herpes simplex virus type 1 (HSV-1) causes recurrent infections of skin and mucosal tissues with high global prevalence. HSV-1 also invades the nervous system where it establishes a lifelong latency-making infection poorly treatable We previously showed that both tannic acid-modified silver gold nanoparticles (TA-Ag/AuNPs) inhibit in vitro. Methods: used an vitro vivo model to study how metal type, size acid modification can influence development early innate response mounting...
