“…Wound healing, as a complexed multi-stage process, necessitates the early inhibition of bacterial infection and the subsequent process of promoted tissue reconstruction. Given the risk of bacterial resistance caused by broad-spectrum antibiotics, various novel antibacterial strategies have been developed for the early treatment of wounds, including photothermal, [7,8] reactive oxygen species (ROS), [9] piezoelectrically active [10,11] and cationic polymer antibacterial. [12] Silver nanoparticles were proposed to improve the synergistic antibacterial properties of Gel-DA/GG@Ag hydrogels, [13] but higher doses or longer periods of application will increase the risk of cumulative toxic heavy metals in living organisms.…”

Advanced sustainable biomedical materials are urgently needed for clinical applications; however, developing biomedical materials with exceptional mechanical and bactericidal properties as well as removable functionalities to reduce unintended secondary injury remains a challenge. Here, we report a biomass‐derived composite consisting of water‐soluble fish gelatin (FG) and antibacterial ZnO@silk fibroin (ZSF) microspheres for potential application as the wound dressing. The ZSF microspheres are embedded in a FG matrix to realize the stretchable, antibacterial, and removable ZSF/FG composites. By introducing glycerin as the plasticizer, ZSF/FG composites deliver a tensile strength of 4.5 MPa and stretchability of 550%. Acting as both the germicide and hydrophile components, ZSF microspheres endow the composites with excellent antibacterial capacity and water solubility. To prevent secondary injury, the ZSF/FG composites can be easily removed from the wounds by simply exposing them to excess water. Additionally, the ZSF/FG composites exhibit favorable biocompatibility and sustain high cell viability of over 100%. The full‐thickness skin wound model on infected mice demonstrated an efficient rate of wound closure and a reduced inflammatory response. The ZSF/FG composite shows promise to hasten the healing of infected wounds and is expected a promising candidate as wound dressing for clinical therapy.

“…Fabrics are widely used in a variety of environments where the attachment of microbial pathogens can pose a potential threat to human health. − Several types of antimicrobial agents, including metallic particles, have been approved for use on fabrics, − but there are cases where the antimicrobial ability weakens and disappears over time. In comparison to the addition of easily leached antimicrobial agents, composites with excellent antimicrobial properties can be achieved by introducing antimicrobial functional groups, such as the quaternary ammonium group, into polymer molecules during the synthesis of polymeric quaternary ammonium antimicrobial polymers. − The presence of a dense and uniform distribution of E.…”

“…To reduce the risk of bacteria-infection in the high-humidity environment, the rational structure design is essential for smart fabrics . Besides, EMW radiations prevalent in intelligent era are also prone to threatening baby health, boosting the introduction of new materials. − Consequently, a water/bacteria-repellence and EMW protection strategy through micro/nanostructuring functional coating is particularly important for smart fabrics. Eventually, the synergy of coating structures and components would achieve smart fabrics, posing higher requirements for the fabrication of coating and selection of functional coating materials.…”

Continuous monitoring of physiological health status and effective protection against external hazards is an indispensable aspect of healthcare management for critically vulnerable populations, particularly for infants or babies. So, the exploration of all-in-one devices remains critical to avoiding their injury and illness. The integration of multiple properties such as sensing, electromagnetic protection, warming/cooling, and water/ bacterial repellence into a common fabric is no doubt a promising solution to coping with diverse application scenarios. However, achieving simultaneous integration in an effective and durable fashion faces huge challenges. Herein, multifunctional fabric was achieved by sequentially coating MXene, carbon nanotubes (CNTs), and self-healing polyurethane (PU) onto cotton fabric. The outstanding conductivity of MXene and CNTs as well as the self-healing ability of PU synergistically enable a flexible, breathable, protective, and sensing fabric with a good durability. It could detect the body motions like bending of the finger, elbow, wrist, and knee, with a high gauge factor of 8.78 and fast response. Moreover, this sensing fabric could protect the wearers against electromagnetic waves and bacteria, delivering a minimum reflection loss of −57.6 dB at 7.6 GHz and high bacterial inhibition efficiency due to the incorporation of MXene and polyethylenimine. Besides, the electrothermal performance of carbonaceous materials enables them to act as a heater for body warmth. The synergistic design of this multifunctional textile offers a promising strategy for producing advanced smart textiles, holding great promise in infant or baby healthcare.
