Here, a covalent organic polymer (COP)-based antibacterial agent, denoted as PF-COP, was developed. PF-COP has intrinsic photothermal capacity, which allows it to take advantage of the infected microenvironment for enhanced synergistic wound infection therapy. PF-COP was prepared via the copolymerization of piperazine with ferrocene diformaldehyde using catalyst-free aminal chemistry, in which the piperazine units could easily bind with acid to generate the cationic skeleton, while the ferrocene components could convert the endogenous H₂O₂ into a toxic hydroxyl radical. This effectively regulates the infection of the microenvironment. The acidified positively charged structures could enhance material adhesion with bacterial cell membranes and improve photothermal responsiveness, significantly improving the therapeutic effect. As a result, PF-COP amalgamating photothermal and enzyme catalytic capacities could serve as an infection microenvironment-enhanced therapeutic agent. It could disrupt the balance of the infection microenvironment, destroying the optimal growth environment for bacteria and inducing “bacterial suicide”, and regulate the microenvironment to promote the growth of normal cells, thus accelerating the wound healing. Therefore, this work presents a promising construction strategy for the precise development of COP-based therapeutics facilitating wound healing through direct infectious microenvironment utilization and regulation.</p>","PeriodicalId":7,"journal":{"name":"ACS Applied Polymer Materials","volume":"6 22","pages":"13764–13774 13764–13774"},"PeriodicalIF":4.4,"publicationDate":"2024-11-08","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142691551","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"化学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The challenge is to go beyond conventional epoxy networks based on visphenol A diglycidyl ether (DGEBA), which firstly contain bisphenol A (BPA) and secondly cannot be recycled. Here, a generation of recyclable epoxy thermosets was designed and developed for the first time from the copolymerization between tri- and tetra-IL based monomers containing cleavable bonds with conventional anhydride (MTHPA) with our without the presence of a metallic ionic liquid (MIL). Thus, the influence of these monomers and the MIL on the curing kinetics, the epoxy conversion, and the physical properties of the resulting networks was assessed. In particular, the combination of the two has proved to be a powerful tool to tailor the architecture–physical property relationships of the resulting IL-modified epoxy networks and to produce recyclable networks.

Notably, PTF1, featuring a single fluorine atom, effectively tunes the energy levels and promotes beneficial intermolecular interactions with the corresponding nonfullerene acceptor. Moreover, PTF1 demonstrates enhanced aggregation and crystallinity, leading to efficient charge generation and transport, resulting in binary and ternary OSCs with PCEs of 13.0% and 18.6%, respectively.

Here, we propose piezoelectric stimulation as a potential osteogenic cue mimicking the electroactive properties of bone's extracellular matrix. When combined with a magnetostrictive component, piezoelectric polymers can be used for MSC stimulation by applying an external magnetic field. The deformation of the magnetostrictive component produces a deformation in the polymer matrix, generating a change in the surface charge that induces an electric field that can be transmitted to the cells. Cell adhesion, cytoskeleton changes, and metabolomics are the first evidence of MSC osteoblastogenesis and can be used to study initial MSC response to this kind of stimulation. In the current study, poly(vinylidene) fluoride (PVDF) piezoelectric films with and without cobalt ferrite oxide (CFO) crystallized from the melt in the presence of the ionic liquid 1-butyl-3-methyl-imidazolium chloride ([Bmim][Cl]) were produced. [Bmim][Cl] allowed the production of the β-phase, the most electroactive phase, even without CFO. After ionic liquid removal, PVDF and PVDF-CFO films presented high percentages of the β-phase and similar crystalline content. Incorporating CFO nanoparticles was effective, allowing the electromechanical stimulation of MSCs by applying a magnetic field with a bioreactor. Before stimulation, the initial response of MSCs was characterized in static conditions, showing that the produced films were biocompatible and noncytotoxic, allowing MSC adhesion and proliferation in the short term. Stimulation experiments revealed that MSCs electromechanically stimulated for 3 days in PVDF-CFO supports showed longer focal adhesions and decreased vimentin cytoskeletal density, both signals of early osteogenic differentiation. Furthermore, they rearranged their energy metabolism toward an osteogenic phenotype after 7 days of culture under the same stimulation.
