A Biodegradable Supramolecular Adhesive with Robust Instant Wet Adhesion for Urgent Hemostasis and Wound Repair

“…LA causes bacterial death by disrupting the synthesis of membrane proteins and interfering with bacterial metabolism. [ 33 ] On the other hand, GA possesses a pyrogallol group, which can efficiently kill bacteria by rupturing their cell membranes, interfering with their metabolism, and preventing the creation of their DNA. [ 16,34 ] Moreover, the positively charged $${\mathrm{NH}}_{\mathrm{3}}^{\mathrm{ + }}$$ of PL is capable of interacting with the negatively charged surface of bacterial cell membranes, further enhancing the antibacterial effect of the system.…”

Intelligent Materials and Nanomaterials Improving Physical Properties and Control Oriented on Electronic Implementations

“…A possible evolution in the fabrication of advanced nanocomposite materials is in the AI control of the physical states of hybrid circuits (solid/liquid) for intelligent adaptive micro-robot implementations. Other important properties of intelligent materials are self-healing [67][68][69][70][71][72][73][74][75][76][77][78][79][80][81] (as in polymer composites based on graphene and carbon nanotubes (CNT) and PDMS) and the shape memory effect [82][83][84][85][86][87][88] (as in ferroic nanocomposites and nanocomposite hydrogels). AI data processing could be adopted to regenerate micro-and nano-electronic circuits and to enable shape auto-adaptive actions controlling external stimuli.…”

A tough, anti-freezing, and low-dehydration rate gelatin hydrogel with inverse temperature-dependent ionic conductivity

“…As soft conductive materials, hydrogels provide a plethora of advantageous properties, including ease of design, excellent stretchability, robust toughness, high conductivity, and considerable biocompatibility. [10][11][12][13] Numerous methodologies, including crosslinking, 14,15 utilization of the salting-out effect, 16,17 compositing with nanomaterials, 18,19 and establishment of double networks, 20,21 have been employed to confer both mechanical toughness and conductivity to hydrogels. Additionally, these hydrogels have been innovatively engineered to possess anti-freezing characteristics and resistance to dehydration, enabling functional performance across a wide temperature range and over extended periods.…”
