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...
The interaction between silver nanoparticles and herpesviruses is attracting great interest due to their antiviral activity possibility use as microbicides for oral anogenital herpes. In this work, we demonstrate that tannic acid modified sized 13 nm, 33 nm 46 are capable of reducing HSV-2 infectivity both in vitro vivo. was size-related, required direct blocked virus attachment, penetration further spread. All tested reduced infection inflammatory reaction the mouse model when used at or a...
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 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...
Mucoadhesive gelling systems with tannic acid modified silver nanoparticles were developed for effective treatment of herpes virus infections. To increase nanoparticle residence time after local application, semi solid formulations designed from generally regarded as safe (GRAS) excipients investigated their rheological and mechanical properties followed ex vivo mucoadhesive behavior to the porcine vaginal mucosa. Particular effort was made evaluate activity nanoparticle-based hydrogels...
(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...
Gold nanoparticles labeled with <sup>211</sup>At are very effective in radionuclide therapy.
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...
Superhydrophobic surfaces were obtained by superposition of microstructure—defined replication laser micromachined masters, with nanostructure—created durable epoxy/ γ ‐Al 2 O 3 nanoparticle composite, used for replication. Hierarchical surface topography thus consisted hexagonally spaced microcavities and agglomerates, exposed on the replica radio frequency (RF) air plasma etching. Surface was further enhanced rims around microcavity edges, resulting from nanosecond micromachining defects...
A study on the functionalization of cotton and viscose fabrics to achieve bifunctional conductive antibacterial properties was carried out; 0.5 wt% AgNW ethanolic colloid prepared, were dipped dried in 1, 10 15 times.

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.
