Samson Afewerki,Samson Afewerki,Amir Sheikhi,Soundarapandian Kannan,Soundarapandian Kannan,Soundarapandian Kannan,Samad Ahadian,Ali Khademhosseini +7 more
TL;DR: G gelatin–polysaccharide biomaterials benefit from mechanical resilience, high stability, low thermal expansion, improved hydrophilicity, biocompatibility, antimicrobial and anti‐inflammatory properties, and wound healing potential.
Journal ArticleDOI
Smart Biomaterials: Recent Advances and Future Directions.
TL;DR: Recent advances in the current state-of-the-art design and application of smart biomaterials in tissue engineering, drug delivery systems, medical devices, and immune engineering are described.
Journal ArticleDOI
Effect of ionic strength on shear-thinning nanoclay-polymer composite hydrogels
Amir Sheikhi,Samson Afewerki,Samson Afewerki,Rahmi Oklu,Akhilesh K. Gaharwar,Ali Khademhosseini +5 more
TL;DR: It is shown that the formation of nanoclay-polymer aggregates due to the ion-induced shrinkage of the diffuse double layer and eventually the liquid-solid phase separation decrease the resistance of STB against elastic deformation, decreasing the yield stress.
Journal ArticleDOI
Combined Catalysis for Engineering Bioinspired, Lignin-Based, Long-Lasting, Adhesive, Self-Mending, Antimicrobial Hydrogels
Samson Afewerki,Xichi Wang,Xichi Wang,Guillermo U. Ruiz-Esparza,Guillermo U. Ruiz-Esparza,Cheuk-Wai Tai,Xueying Kong,Shengyang Zhou,Ken Welch,Ping Huang,Rhodel Bengtsson,Chao Xu,Maria Strømme +12 more
TL;DR: The combination of two catalytic cycles (combined catalysis) comprising oxidative decarboxylation and quinone-catechol redox catalysis for engineering lignin-based multifunctional antimicrobial hydrogels that are robust and elastic, have strong antimicrobial activity, are adhesive to skin tissue and various other surfaces, and are able to self-mend.
