In contrast, synthetic food colorants are often suggested to be associated with adverse health effects yet are known to have relatively high color stability during processing and storage. Unlike artificial colorants, natural pigments are somewhat unstable and susceptible to chemical and enzymatic degradation, leading to enhanced color loss. Therefore, their use as pigments is constrained, and stabilization by hydrocolloids is being explored. In addition to the texturizing properties of hydrocolloids, they can interact with natural pigments, affecting their stability. Therefore, hydrocolloids can improve the chemical and physical stability of pigments, resulting in enhanced color stability. This review summarizes up-to-date information regarding the stabilization of natural pigments such as anthocyanins, betalains, carotenes, C-phycocyanins, and chlorophylls, using hydrocolloids, in relation to the hydrocolloid properties, pigment structure, and stabilization methods and mechanisms.</div>","PeriodicalId":293,"journal":{"name":"Current Opinion in Colloid & Interface Science","volume":"68 ","pages":"Article 101756"},"PeriodicalIF":8.9,"publicationDate":"2023-09-14","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"91984975","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}

However, recent data recorded on single congeners question the actual pertinence of using the word ‘biosurfactant’ associated to these molecules. By evaluating the accepted characteristics of surfactants and comparing them to the actual self-assembly and bulk properties in water of molecules traditionally called ‘biosurfactants’, this opinion article aims at showing that the term ‘biosurfactant’ can be somewhat reductive when applied to specific individual compounds produced by fermentation.

Because of changes in charge distribution and protection of cleavage sites, self-assembled peptides can have high resistance to enzymatic degradation. As potential candidates for biomedical applications, it is important to understand how peptides self-assemble and how the processes can be manipulated. Following the diverse approaches recently reported to control their assembling processes, many de novo-designed short peptides can be applied to infection control in various conditions, such as nanocarriers in drug delivery, wound dressings, and postsurgery antimicrobial/antiviral spreads and coatings. Here we present an overview of recent advances in peptide self-assembly mechanisms and the relationship between self-assembly behaviors and their infection-combatting effects.

Traditional diagnostic approaches rely on centralized laboratory tests that result in long wait times to results and reduce the number of tests that can be given. Point-of-care tests (POCTs) are a group of technologies that miniaturize clinical assays into portable form factors that can be run both in clinical areas —in place of traditional tests— and outside of traditional clinical settings —to enable new testing paradigms. Hallmark examples of POCTs are the pregnancy test lateral flow assay and the blood glucose meter. Other uses for POCTs include diagnostic assays for diseases like COVID-19, HIV, and malaria but despite some successes, there are still unsolved challenges for fully translating these lower cost and more versatile solutions. To overcome these challenges, researchers have exploited innovations in colloid and interface science to develop various designs of POCTs for clinical applications. Herein, we provide a review of recent advancements in lateral flow assays, other paper based POCTs, protein microarray assays, microbead flow assays, and nucleic acid amplification assays. Features that are desirable to integrate into future POCTs, including simplified sample collection, end-to-end connectivity, and machine learning, are also discussed in this review.</div>","PeriodicalId":293,"journal":{"name":"Current Opinion in Colloid & Interface Science","volume":"66 ","pages":"Article 101718"},"PeriodicalIF":8.9,"publicationDate":"2023-08-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.ncbi.nlm.nih.gov/pmc/articles/PMC10247612/pdf/","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"3208431","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}
