Bacterial Enzymes and Antibiotic Resistance

Acta Naturae, 2018
The resistance of microorganisms to antibiotics has been developing for more than 2 billion years and is widely distributed among various representatives of the microbiological world. Bacterial enzymes play a key role in the emergence of resistance.

Biocompatible but Antibacterial Mechanism of Graphene Oxide for Sustainable Antibiotics

Advanced Functional Materials, EarlyView.
Graphene oxide (GO) exhibits selective antibacterial activity through specific interactions between its oxygen functional groups and bacterial membrane phospholipid POPG, causing membrane destabilization while maintaining biocompatibility. Model membrane studies and infected wound models in mice and pigs demonstrate effective bacterial suppression and ...

Silicified Wood‐Inspired, High‐Strength Fire‐Resistant Chitin‐Based Aerogels for Sustainable High‐Temperature Thermal Insulation

Advanced Functional Materials, EarlyView.
Inspired by natural silicified wood, a biomimetic mineralized chitin‐derived aerogel is constructed. It can withstand 81 000 times its own weight, and its backside temperature is 130.4°C after exposure to ∼1300°C butane flame for 600 s, exhibiting high‐strength, fire‐resistance, and super thermal‐insulation properties.

Coating Artificial Spider Silk Fiber with Magnetic FeCo: An Effective Strategy for Creating a Flexible Magneto‐Responsive Material

Advanced Functional Materials, EarlyView.
An original method is presented for producing artificial spider silk fibers with magnetic and magnetomechanical responsiveness, which consists in coating them with a nanometer‐thick layer of FeCo alloy by sputtering deposition. The challenge of combining organic materials and inorganic magnetic nanostructures is addressed, thus taking a step forward ...

Co‐Electrospinning Extracellular Matrix with Polycaprolactone Enables a Modular Approach to Balance Bioactivity and Mechanics of a Multifunctional Bone Wrap

Advanced Healthcare Materials, EarlyView.
The incorporation of nondigested ECM and synthetic polymers into a co‐electrospinning system enables the decoupling of bioactivity and mechanical properties within a single wrap. This technique is used to develop a multifunctional bone wrap that achieves augmented membrane durability, sustained infection control, and enhanced vascularity for use in ...
