The objective of this study was to determine the in vitro percutaneous penetration of silver and characterize the silver species released from textiles in different layers of full thickness human skin. For this purpose, two different wound dressings and a garment soaked in artificial sweat were placed in the donor compartments of Franz cells for 24 hours. The concentration of silver in the donor phase and in the skin was determined by an electrothermal atomic absorption spectrometer (ET-AAS) and by inductively coupled plasma mass spectrometer (ICP-MS).

These enable a close contact with human skin, thanks to the large release of silver ions that is responsible for a broad spectrum of antimicrobial activity. Silver can permeate the skin; however, there are no data available on silver permeation through skin grafts commonly used in burns recovery.

- Contact sensitization patterns to allergens vary by country, influenced by exposure differences, with a focus on data from 2007-2008.
- Analysis of patch test results from over 25,000 patients revealed metals and fragrances as the most common allergens, with potential new additions like methylisothiazolinone.
- The findings suggest certain countries show higher rates of specific sensitization, indicating a need for further research into exposure causes and potential updates to the baseline allergen series.
For their antibacterial activity, silver nanoparticles (Ag NPs) are largely used in various commercially available products designed to come in direct contact with the skin. In this study we investigated the effects of Ag NPs on skin using the human-derived keratinocyte HaCaT cell line model. Ag NPs caused a concentration- and time-dependent decrease of cell viability, with IC(50) values of 6.

Using three database, PubMed, Scopus, and EMBASE, we found 57 papers on this topic, and on possibly related upper limb symptoms and diseases. In these studies, evaluation of the risk, e.
