“…To further verify the synergistically enhanced antibacterial effect in CTS-APs@DMY, a small amount of the bacterial solution coculture with CTS-APs@DMY for 6 h was extracted and observed. 19 Different from the normal morphology of the bacteria (Figure S9), Figure 4a inward and membrane rupture on E. coli and S. aureus cells after CTS-APs@DMY treatment. This suggests that CTS-APs@DMY disrupts the integrity of the cell membrane and increases its permeability, leading to bacterial inactivation.…”

“…As shown in Figure 1c, the average diameter of the CTS-based derivative was reduced from 473.7 to 229.8 nm after constructing CTS-APs@DMY, which can be ascribed to the influence of π−π stacking after the introduction of DMY. 19,34 It is worth noting that the small size of the nanocomposite is more conducive to the contact and invasion of natural polymers with bacteria. 35 To more intuitively explore the size difference of samples, we further observed the microstructure of CTS, CTS-APs, and CTS-APs@DMY was further observed.…”

The development of biobased antibacterial nanomaterials for normal-temperature food preservation is important to prevent foodborne pathogenic infections and achieve low-carbon life. Herein, we developed a biodegradable self-assembling polymer-based nanocomposite with efficient antibacterial activity through the copolymerization of chitosan units with Astragalus polysaccharides and functional dihydromyricetin. The as-prepared irregular spherical-type nanocomposite exhibited multidimensional antibacterial action such as cell membrane devastation, cellular leakages, and respiratory disturbance (ATP pathway), thereby achieving an efficient inhibition in vitro against Gram-negative Escherichia coli (E. coli) and Gram-positive Staphylococcus aureus (S. aureus). After the natural deposition of the designed nanocomposite onto a commercial fiber paper (FP), the resulting modified FP was found to possess remarkable pathogen eradication, enhanced UV shielding, and improved water vapor barrier properties. As a proof-of-concept demonstration, the shelf life of salt-baked chicken (processed food) packaged in the modified FP was extended to 5 days in a room-temperature environment. Therefore, the simple design and validation of polymerbased nanocomposite in this work will provide a good reference for room-temperature food preservation technology.

In the context of increasingly complex living environments, it is crucial to develop smart indoor wall materials for resisting external interference such as humidity changes. Herein, we report a facile and scalable strategy to prepare advanced polyurethane (PU) foam as a multifunctional indoor wall, integrating solar-driven humidity regulation, noise absorption, and flame retardancy. Benefiting from the in situ synthesis technology to maintain the original metal−organic framework (MOF) porosity (0.149 cm 3 /g) and realize a high MOF loading (63.72%), the advanced PU-based module showed excellent water collection abilities and fast water transport kinetics. As a proof-of-concept demonstration, the designed PU-based regulation system provided a comfortable humidity environment (40−70% RH) of a simulated room in outdoor experiments, dependent on the automatic water collection of the Al-fumarate backbone at night as well as the continuous water evaporation promoted by the photothermal layer during daytime. Therefore, the developed multifunctional PU-based management module has great potential for constructing modern, comfortable, and energy-efficient indoor environments.
