“…As peptide molecules infiltrated the inner pores of the MOF, they coalesced on the pore surface, forming larger clusters or aggregates, thus augmenting the dimensions of the MOFs. In Figure E,F, the distribution of elements in LZIF-8, or WMg-MOF was examined using EDS (energy-dispersive X-ray spectroscopy). , The results demonstrated a homogeneous dispersion of elements within the crystal with LZIF-8 containing Zn elements from ZIF-8 and O elements derived from the peptides. WMg-MOF contained Mg elements, although distinguishing the origin of other elements between Mg-MOF and the peptides was inconclusive.…”

The tendon−bone interface has a complex gradient structure vital for stress transmission and pressure buffering during movement. However, injury to the gradient tissue, especially the tendon and cartilage components, often hinders the complete restoration of the original structure. Here, a metal ion network hydrogel scaffold, with the capability of targeting multitissue, was constructed through the photopolymerization of the LHERHLNNN peptide-modified zeolitic imidazolate framework-8 (LZIF-8) and the WYRGRL peptide-modified magnesium metal− organic framework (WMg-MOF) within the hydrogel scaffold, which could facilitate the directional migration of metal ions to form a dynamic gradient, thereby achieving integrated regeneration of gradient tissues. LZIF-8 selectively migrated to the tendon, releasing zinc ions to enhance collagen secretion and promoting tendon repair. Simultaneously, WMg-MOF migrated to cartilage, releasing magnesium ions to induce cell differentiation and facilitating cartilage regeneration. Infrared spectroscopy confirmed successful peptide modification of nano ZIF-8 and Mg-MOF. Fluorescence imaging validated that LZIF-8/WMg-MOF had a longer retention, indirectly confirming their successful targeting of the tendon−bone interface. In summary, this dual-targeted metal ion network hydrogel scaffold has the potential to facilitate synchronized multitissue regeneration at the compromised tendon−bone interface, offering favorable prospects for its application in the integrated reconstruction characterized by the gradient structure.

“…The AFM image in Figure e illustrates the large surface roughness of PhCs, with an RMS of 34.1 nm. The high roughness contributed to enhancing the surface hydrophobicity . When compared to PDMS, the contact angle of PQDs dispersed on the PhCs increased from 51° to 89°, indicating an increase in hydrophobicity (Figure f).…”

In response to growing concerns about public safety and environmental conservation, it is essential to develop a precise identification method for trace explosives. To improve the stability and detection sensitivity of perovskite quantum dots (PQDs) and address the issue of low porosity in traditional polymer-based photonic crystals (PhCs), this study proposed a PQD photoluminescence (PL) enhancement strategy based on the slow light effect of ZIF-8 PhCs for highly sensitive, selective, and convenient detection of 2,4,6-trinitrophenol (TNP). The slow light effect at the photonic band gap edge is the basis of amplifying the PL signal. PhCs were fabricated by the evaporation-induced self-assembly method. The diffraction wavelength overlapping the whole visible region was designed to match the emission wavelength of PQDs. Results showed that PhCs matching the PBG edge with PQDs' emission peak amplified the PL signal 11.3 times, significantly improving sensitivity for trace TNP detection with a limit as low as 2.52 nM. Moreover, there was a 13.3-fold enhancement of PQDs' fluorescence lifetime when the emission wavelength fell in the PBG range. The hydrophobic surface of ZIF-8 PhCs enhanced the PQDs' stability and moisture resistance. Furthermore, the selective quenching mechanism of TNP by the sensor was photoinduced electron transfer (PET) verified by DFT calculations and time-resolved PL decay dynamics measurements. This study demonstrated great potential for manipulating light emission enhancement by PhCs in developing efficient fluorescent sensors for trace environmental pollutant detection.

“…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.…”
