These BSs possess a diverse range of physical, chemical, and biological properties. In recent years, researchers have combined these biosurfactants with both natural and synthetic polymers, resulting in the development of advanced material systems that exhibit a unique combination of properties. This review focuses on highlighting the recent advancements in these biosurfactant-polymer material systems and identifies existing gaps in the literature. The combination of biosurfactants with polymers has led to the formation of interpenetrated hydrogels, films, chemically modified surfaces, vesicles, functionalized nanofiber non-woven mats, nano-formulations, and nano-assemblies. Some studies have also investigated the interactions between biosurfactants and polymer molecules. In most cases, non-specific, non-covalent interactions, such as electrostatic interactions, hydrogen bonding, and hydrophobic interactions have been found to govern the properties of these systems. Moreover, promising results have been achieved through the covalent modification of polymer surfaces, followed by functionalization using biosurfactant molecules. The literature demonstrates that these advanced materials could find applications in various fields, including drug delivery, bioremediation, biomedical materials, and as antimicrobial agents. These findings indicate the promising potential of biosurfactant-polymer systems for future advancements in these areas.</p></div>","PeriodicalId":293,"journal":{"name":"Current Opinion in Colloid & Interface Science","volume":"72 ","pages":"Article 101806"},"PeriodicalIF":8.9,"publicationDate":"2024-04-27","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"140927152","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}

In this review, we discuss literature findings, mostly reported in the last decade, on the self-assembly of the four main classes of microbial biosurfactants, <em>i.e.</em>, rhamnolipids, mannosylerythritol lipids, sophorolipids, and surfactin. All of them present composite molecular structures, characterized by different functional groups and ionisable moieties, and a high conformational flexibility. Where possible, we discuss the formation of different aggregate morphologies in terms of biosurfactant molecular structure and variation of environmental parameters. We highlight how the biosurfactant self-assembly is regulated by a complex interplay between various intermolecular interactions, including H-bonds and steric constraints, besides electrostatic and hydrophobic interactions. For this reason, we show that common theoretical approaches to amphiphile self-assembly, such as the critical packing parameter, have limitations in rationalizing and predicting biosurfactant aggregation behaviour.</p></div>","PeriodicalId":293,"journal":{"name":"Current Opinion in Colloid & Interface Science","volume":"70 ","pages":"Article 101792"},"PeriodicalIF":8.9,"publicationDate":"2024-02-09","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.sciencedirect.com/science/article/pii/S1359029424000104/pdfft?md5=ddb5edf77569fd45576a9e974856fa99&pid=1-s2.0-S1359029424000104-main.pdf","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"139893697","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"化学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

This review discusses glycation as a biolubrication tool to provide stimulus to future designing of food colloids. Specifically, we examine how glycation drives biolubrication of soft tissues with examples of lubricin and mucin as “brush-like”, nature-engineered, high performance, aqueous lubricants. Recent advances in Maillard conjugation to modify tribology, rheology, adsorption, or surface hydrophobicity of dietary proteins are covered. Lastly, we transfer molecular rules from polymer physics to food colloid science to inspire repurposing glycation of dietary proteins to rationally design the next-generation of lubricious alternative protein-based foods that are often delubricating.</p></div>","PeriodicalId":293,"journal":{"name":"Current Opinion in Colloid & Interface Science","volume":"69 ","pages":"Article 101782"},"PeriodicalIF":8.9,"publicationDate":"2023-12-08","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.sciencedirect.com/science/article/pii/S1359029423001073/pdfft?md5=29f21841f17655ef44ae9b4bd98f5e3a&pid=1-s2.0-S1359029423001073-main.pdf","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"138556076","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"化学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
