Light‐Activated Tissue‐Integrating Sutures as Surgical Nanodevices

Surgical Sutures: An overview

Sutures are used to close the cuts caused by injuries or to close the incision due to surgery and other medical procedures like wound approximation. They are commonly used on the skin, internal tissues, organs and blood vessels. They are available in the form of monofilament, multifilament/braided and pseudo monofilament. A lubricant is applied on the surface of braided suture material to lower...

Force Sensing in Surgical Sutures

The tension in a suture is an important factor in the process of wound healing. If there is too much tension in the suture, the blood flow is restricted and necrosis can occur. If the tension is too low, the incision opens up and cannot heal properly. The purpose of this paper is to describe the design and evaluation of the Stitch Force (SF) sensor and the Hook-In Force (HIF) sensor. These sens...

Ionic Channels as Natural Nanodevices

Bacterial adherence to surgical sutures: can antibacterial-coated sutures reduce the risk of microbial contamination?

BACKGROUND Surgical site infections are associated with severe morbidity and mortality. The role of surgical sutures in the etiology of surgical site infection has been the objective of discussion for decades. This study used a standardized in vitro microbiologic model to assess bacterial adherence and the antibacterial activity of a triclosan-coated polyglactin 910 (braided) suture against sel...

Nanofibrillar cellulose-alginate hydrogel coated surgical sutures as cell-carrier systems

Hydrogel nanomaterials, especially those that are of non-human and non-animal origins, have great potential in biomedical and pharmaceutical sciences due to their versatility and inherent soft-tissue like properties. With the ability to simulate native tissue function, hydrogels are potentially well suited for cellular therapy applications. In this study, we have fabricated nanofibrillar cellul...
