In Situ Growth of Silver Nanoparticles into Reducing-End Carbohydrate-Based Supramolecular Hydrogels for Antimicrobial Applications Hydrogels with antibacterial activities have the potential for many biomedical applications, such as wound healing, because of their capacity to maintain a moist environment and prevent infections. In this work, an ultrasound-induced supramolecular hydrogel consisting of easily accessible reducing-end-free glucosaminylbarbiturate-based hydrogelators that serve the in situ fabrication of silver nanoparticles (AgNPs), excluding the addition of any external reducing or stabilizing agents, has been developed. The innovative synthetic approach relied on the use of N,N′-disubstituted barbituric acid derivatives as a versatile chemical platform that site-selectively reacted with the amino function of glucosamine. A series of glucosaminylbarbiturate were synthesized, and we identified one carbohydrate-based hydrogelator that produced a thixotropic supramolecular hydrogel after ultrasound-mediated breaking of an intralocked hydrogen bond. AgNPs@hydrogels were prepared through in situ reduction of silver ions mediated by the reducing properties of carbohydrates. The AgNPs@hydrogel composite revealed good antimicrobial properties toward both Gram-positive and Gram-negative bacteria. These findings contribute to the development of carbohydrate-based supramolecular hydrogels and make them promising efficient and safe soft materials for antimicrobial therapy.

Hello Bluesky community. I'm delighted to share our recent publication in ACS Applied Materials & Interfaces related to the in situ preparation of silver nanoparticles in a reducing sugar-based supramolecular hydrogel matrix for antibacterial application. @cermav.bsky.social

A sweet introduction of our CNRS Institute - CERMAV - where glycochemistry, glycobiology and glycomaterials are in action to promote
Glycan-based renewable resources towards functional materials and to better understand the role of carbohydrates in living systems.
