Bernards, Waynant Publish Article on Stealth Coating to Aid Implant Acceptance

August 03, 2021

An article co-authored by University of Idaho Chemical Engineering Associate Professor Matt Bernards and Chemistry Assistant Professor Kristopher Waynant was recently published in Biomaterials Science in their “Recent HOT Articles” collection.

The article, “Synthesis of a zwitterionic N-Ser–Ser-C dimethacrylate cross-linker and evaluation in polyampholyte hydrogel,” focuses on using an amino-acid based molecule as a coating for implants to keep them from being rejected by the body.

“When a foreign object goes into the body, it detects that object and tries to destroy it,” Bernards said. “The hope is that, if we can prevent that detection step, we can enhance tissue regeneration through that material.”

Coating implants in this stealth biomaterial will be the first step toward major progress in preventing that detection process, and a provisional patent is in place. U of I faculty will collaborate with researchers at Washington State University to begin studying the effectiveness of this new coating material.
