The overlapping symptoms of cirrhosis and sepsis make early diagnosis particularly challenging, emphasizing the need for reliable biomarker diagnostic tools. Conventional methods are slow and result in delayed treatment, deteriorating liver function in cirrhotic patients over time. Electrochemical biosensors have emerged as promising solutions, offering rapid and precise detection of both host- and pathogen-related proteins. These platforms overcome many limitations of traditional diagnostic methods, providing enhanced sensitivity and specificity. Furthermore, the ability of the electrochemical platform to simultaneously detect multiple biomarkers has improved the sensor's reliability for comprehensive point-of-care diagnostics in clinical settings.

In this study, we attempt to develop liposomal-spherical nucleic acid (LSNA), which is modified with nucleic acids on the liposomes, that would cause a pH-responsive change in the platform membrane that is effective for drug delivery. pH-responsive function was induced by modifying DNA that forms i-motifs to the lipid membrane surface of liposomes. In particular, the formation of i-motifs is expected to cause perturbation on the lipid membrane and release drugs encapsulated into liposomes. The performance of drug release can be controlled by the adjustment of the i-motif formation and membrane properties. Two types of i-motifs were selected for LSNAs to investigate whether i-motif formation of intra- and intermolecular interactions causes differences in lipid membrane perturbation and its drug release performance. Based on a series of fluorescence spectroscopy, the appropriate amount of DNA modification was determined from membrane characterization. DNA-modified liposomes showed a change in membrane fluidity depending on pH, and particularly, the fluidity of the membrane decreased under the condition of intermolecular i-motif formation. From the release pattern of liposomal-encapsulated doxorubicin, a significant increase of drug release was observed under conditions where intermolecular i-motifs were formed.

Moreover, combination therapy employing multiple therapeutic approaches has become a cornerstone of modern oncology, aiming to enhance treatment efficacy and overcome resistance mechanisms. This study presents an approach to enhance the effectiveness of PDT and PTT in cancer treatment by synthesizing carbon dots from the organic dye IR-820 and citric acid. The IR820-based carbon dots (IRCDs) were synthesized through a one-step hydrothermal process, inheriting the near-infrared fluorescence properties of IR-820. To facilitate targeted delivery to cancer cells, AS1411 aptamers were conjugated to the surface of IRCDs via EDC/NHS chemistry, forming IRCDs@AS1411. This transformation of IR-820 into carbon dots not only preserved its NIR fluorescence and therapeutic functionalities but also significantly enhanced the chemical stability, photostability, and resistance to photobleaching of the resulting nanomaterials. Notably, IRCDs@AS1411 exhibited a photothermal conversion efficiency approximately 35% higher than that of free IR-820. In vitro experiments demonstrated that IRCDs@AS1411 served as effective agents for bioimaging, PDT, and PTT, overcoming the limitations of traditional organic dyes and efficiently eradicating tumor cells under 808 nm laser irradiation. These findings suggest that IRCDs@AS1411 hold significant promise for advanced cancer therapy and provide a versatile platform for developing other functional nanomaterials.</p>","PeriodicalId":2,"journal":{"name":"ACS Applied Bio Materials","volume":" ","pages":""},"PeriodicalIF":4.6,"publicationDate":"2025-07-06","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144574333","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The treatment is further hurdled by the acidic environment of biofilms due to anaerobic glycolysis of bacteria and the accumulation of acidic byproducts. Therefore, there is a need for the development of antimicrobial materials that can selectively and preferentially eradicate biofilms in the acidic environment. Toward this aim, this study explores the use of acid-responsive double-network peptide-polymer hydrogels encapsulated with antimicrobial peptides to effectively target and disrupt biofilms. The hydrogel consists of two essential components: a self-assembling peptide nanofiber containing a non-natural ionic amino acid, which imparts pH responsiveness in the weakly acidic range, and a 4-arm PEG polymer that forms covalent bonds with the peptide nanofiber, enhancing the hydrogel's mechanical strength. Upon acidification, peptide nanofibers disassemble, causing an increased pore size of the hydrogel and release of encapsulated antimicrobials to the biofilm site. We expect that, by leveraging the unique properties of the double network self-assembled peptide-PEG hydrogels and the pH-triggered release mechanism, this innovative hydrogel approach may offer a more targeted, effective, and safer treatment option against biofilm-associated infections.</p>","PeriodicalId":2,"journal":{"name":"ACS Applied Bio Materials","volume":" ","pages":""},"PeriodicalIF":4.6,"publicationDate":"2025-07-06","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144574334","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
