Silver Technologies

Bacterial colonization and infection are considered to contribute to delayed healing. Antimicrobial dressings are recommended for the management of critically colonized wounds. Silver has a well-established history as a broad spectrum antimicrobial dating back to ancient times; it is particularly known for killing bacteria found commonly in the management of chronic wounds. More importantly silver has demonstrated its effectiveness against some antibiotic-resistant bacteria. Silver-containing dressings are widely used to assist with management of infected wounds and those at risk of infection.

UMT has developed a number of silver technologies to incorporate with fibrous wound dressings. There are two types of silver used in antimicrobial wound dressings, one being ionic the other is metallic.


The silver content and release profile are the critical factors contributing to the antimicrobial capability of the dressing.
