New Tissue Glue Can be Clearly Seen With X-Rays and Ultrasound

Researchers at Korea’s Institute for Basic Science and Seoul National University Hospital have designed and tested a glue for binding tissues that also works as a contrast agent for X-rays, CTs, and ultrasound imaging modalities. This is the first such tissue glue to have this set of properties, and, if approved for clinical applications,*may end up displacing other adhesives because it can be later easily monitored as to how it’s holding tissues together.

The material is made of na**particles that have tantalum oxide at their center, a radiopaque material, and a silica exterior that provides the gluing action.

Tested to exhibit less cellular toxicity than a combination of FDA approved cya**acrylate, a tissue adhesive, and lipiodol, a radiopaque contrast agent (CA-Lp), the new material was successfully used to repair a damaged liver, and connect moving tissues of the lung and limbs in laboratory animals. Its radiopaque properties were similar to lipiodol and it was about as visible as cya**acrylate under X-rays.

From Institute for Basic Science:

CA-Lp tends to trigger immune reaction within 3 days from the operation and inflammation after 14-65 days, while experiments showed that TSN did **t show such adverse effects after 56 days.

TSNs also ensured accurate target localization during movement; when TSNs were injected in rat’s thigh and calf muscles, they did **t move even during the flexion and extension of the leg. “TSNs are well fixed to tissues so that na**particles and tissues move in unison.

Here’s a quick video demonstrating the new glue under X-rays:
