Understanding their behavior, evaluating antimicrobial efficacy, developing control strategies, and implementing monitoring systems are crucial steps in mitigating biofilm-related risks. This review explores the integration of rheology and atomic force microscopy techniques as powerful tools for addressing these challenges. Rheological models provide insights into biofilm viscoelastic properties, aiding in monitoring and predicting their behavior under diverse environmental conditions. From bulk rheological characterizations to micro-scale measurements, studies elucidate the complex interplay between environmental factors and biofilm development, informing strategies for disinfection and product optimization. AFM enables visualization of biofilm morphology, quantification of surface roughness, and probing of mechanical interactions at the nanoscale. Integration with other analytical techniques offers comprehensive insights into biofilm structure–function relationships, guiding innovative biofilm management strategies. Current applications span antimicrobial effectiveness assessments, biofilm control strategy design, and monitoring of biofilm contamination across industries. Leveraging interdisciplinary approaches holds promising potential to deepen our understanding of biofilms and develop more effective interventions, safeguarding product quality and human health. This review underscores the pivotal role of rheology and AFM in characterizing biofilms and addressing biofilm-related challenges in these fields, where continued research and innovation are essential for advancing our understanding and enhancing control strategies.</p><h3>Graphic Abstract</h3>\u0000<div><figure><div><div><picture><source><img></source></picture></div></div></figure></div></div>","PeriodicalId":7220,"journal":{"name":"Advanced Composites and Hybrid Materials","volume":null,"pages":null},"PeriodicalIF":23.2,"publicationDate":"2024-09-14","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142248507","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"材料科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Therefore, the significance of wearable smart monitoring devices based on flexible electronic materials cannot be overstated. Numerous researchers have been working tirelessly for this purpose, exploring solutions from various angles, including material choice, circuit design, and algorithmic processing.

The sorbents include silver (Ag) nanoparticles and multilayered Ti<sub>3</sub>C<sub>2</sub>T<sub>x</sub> MXene, both incorporated into the structure of a three-dimensional polyethyleneimine porous cryogel (PEI) that acts as a scaffold holding and exposing nano active sites involved in the removal of Hg.

These M@iCOP hybrids, with NH<sub>2</sub>-UiO-66 serving as an embedded “adsorption engine,” exhibit richer pore channels, which combined with the nitrogen-rich structure and π-π stacking interactions in the shell layer of the iCOPs, which led to a significant enhancement of CO<sub>2</sub> adsorption with up to 3.33 mmol·g<sup>−1</sup> at 0 °C and 1 bar. Remarkably, M@iCOPs-400, which possesses abundant ionic and Lewis acid sites, demonstrates excellent performance in CO<sub>2</sub> conversion under milder conditions through interfacial synergistic effect, affording various cyclic carbonates in 90–99% yields. Overall, this research provides a straightforward and cost-effective approach for constructing core–shell M@iCOP materials.</p></div>","PeriodicalId":7220,"journal":{"name":"Advanced Composites and Hybrid Materials","volume":null,"pages":null},"PeriodicalIF":23.2,"publicationDate":"2024-08-24","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142191961","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"材料科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
