Liposomes synthesized via microfluidic techniques were coated with CSMA to enhance mucoadhesion and prolong residence time through electrostatic and covalent interactions with mucin. Liposomal optimization produced uncoated liposomes measuring 154 nm with a PDI of 0.12, which rose to 208 nm following CSMA coating. The zeta potential shifted from -8.3 to +36 mV, indicating effective functionalization. In vitro, CSMA-liposomes exhibited significant mucoadhesion, resulting in a particle size increase to 369 nm and a zeta potential of +2.4 mV after 4 h of incubation with mucin. Ex vivo retention on bovine conjunctival tissues exhibited enhanced fluorescence retention of CSMA-liposomes relative to untreated and chitosan-coated liposomes. The release of dexamethasone sodium phosphate from CSMA-liposomes demonstrated a sustained, biphasic profile, indicating potential for improved ocular bioavailability and therapeutic effectiveness.</p>","PeriodicalId":30,"journal":{"name":"Biomacromolecules","volume":" ","pages":""},"PeriodicalIF":5.5,"publicationDate":"2025-07-15","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144641234","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}

Control over resorption rates is defined by material properties, which inform the selection of a formulation for specific applications. This review examines the synthesis and degradation behavior of DAPs for biomedical applications. We focus on copolymer DAPs, which offer promising opportunities to tailor resorption by strategically incorporating diverse α,ω-dicarboxylic acid and α,ω-diol monomers. We analyze the molecular and macroscopic factors influencing hydrolytic degradation, correlating these to the copolymer composition. We highlight emerging approaches for assessing degradation behavior through efficient techniques and real-time monitoring capabilities.

As an alternative, biological control agents offer a sustainable approach; however, their efficacy is often limited due to poor stability under varying environmental conditions, underscoring the need for improved formulation strategies. In this study, a pH-responsive hydrogel system was designed by combining tunicate-derived carboxymethylcellulose (TCMC) with alginate to encapsulate spores of the biocontrol bacterium <i>Bacillus velezensis</i> FZB42. The resulting TCMC hydrogel demonstrated controlled spore release under alkaline conditions and enhanced mechanical strength and thermal stability. These properties effectively suppressed alkaline-favoring fungal pathogens, such as <i>Fusarium graminearum</i>, in vitro assays. Beyond its functional performance, the system provides an environmentally conscious solution by repurposing discarded tunicate shells, a major marine waste byproduct.

A steep reduction in duct diameter at the ASG's onset initiates silk protein transformation, while the extended duct length promotes molecular alignment, crystallization, and orientation. Genetic manipulation to extend ASG length significantly increased the Young's modulus and toughness of silkworm silk fibers.

Herein, we review the use of poly­(oligo­(ethylene glycol) methacrylate) (POEGMA) as a PEG alternative that can provide significantly more synthetic versatility, minimize immunogenicity, and open up additional applications (e.g., thermoresponsive devices) based on precise control over the (co)­polymer composition, the backbone molecular weight, and the side chain molecular weight. The synthetic pathways and applications of POEGMA as a surface or biomolecular grafting agent, a hydrogel, a microgel/nanogel, and a nanoparticle stabilizer are comprehensively summarized, with applications in drug delivery, tissue engineering/wound healing, and biosensing particularly highlighted to show how the unique properties of POEGMA can impart improved or unique application performance.
