Building upon our previous work on maltotriose-modified magnetite nanoparticles (Fe₃O₄-maltotriose), we delve deeper into the research, incorporating the photosensitizer HMME. This integration enables targeted diagnosis of infectious lesions while simultaneously killing bacteria for therapeutic intervention. This study presents the development of a precision drug delivery system (UCNP@SiO₂-maltotrios/HMME) for the treatment of bacterial infections in bones and joints. Through a microemulsion method, we encapsulated mesoporous SiO₂ onto the surface of upconversion nanoparticles (UCNPs). We then loaded the internal space with the photosensitizer porphyrin monomethyl ether (HMME) to release singlet oxygen (¹O₂) upon acoustic activation, and externally loaded maltotriose (maltotrios) as a targeting molecule. Our research investigates the HMME drug loading capacity, and singlet oxygen bactericidal capabilities of this material using a rat infection model. We further evaluated its bactericidal efficacy and biosafety through in vitro cell experiments and in vivo animal studies. Our results demonstrate the excellent luminescence properties and normal imaging capabilities of UCNP@SiO₂-maltotrios/HMME both in vitro and in vivo. Notably, this material exhibits strong precision targeting and antibacterial activity against <i>Escherichia coli</i> and <i>Staphylococcus aureus</i>. Moreover, UCNP@SiO₂-maltotrios/HMME demonstrates no cytotoxicity in cells or organs of mice, indicating its favorable biosafety.</p><h3>Graphical 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":"8 1","pages":""},"PeriodicalIF":23.2,"publicationDate":"2024-12-04","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142762025","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}

PVDF-TrFE is one of the commonly used materials for triboelectric nanogenerators (TENG) because of its high β-phase ratio and strong electron attraction ability. Electrospinning technology can further increase the proportion of β-phase in PVDF-TrFE by electric field polarization. However, the electrospun PVDF-TrFE fiber film has poor mechanical properties and is difficult to be used in electronic devices for a long time. The addition of PMMA can form hydrogen bonds in the fiber, which greatly optimizes the mechanical strength of the blended film. Therefore, in this work, PVDF-TrFE/PMMA electrospun film with mechanical and electrical stability was prepared by electrospinning method. After optimization of materials and working conditions, the optimal output performance of the hybrid membrane TA-TENG can reach 0.215 μA and 210 V. Over 2000 working cycles, the device offers excellent output stability and long-term durability.

In this work, by designing nitrogen-doped porous carbon (NPC) and preparing film with polyvinyl alcohol (PVA), weakly negative permittivity in the radio frequency band is obtained when NPC content reaches 20 wt%. In NPC, the electrons around the doped nitrogen atoms are highly localized, reducing the carrier concentration. In addition, the doped nitrogen makes the band structure flatter, resulting in an increase in the effective electron mass. These two strategies reduce the plasma frequency, thereby achieving weakly negative permittivity (about − 40) from 10 kHz to 1 MHz. Moreover, the porous structure is conducive to electron transfer, achieving high carrier mobility and thus obtaining low dielectric dispersion, so that the negative permittivity is maintained at around − 40 in the range of 10 kHz to 1 MHz, which is almost unaffected by frequency.

The conventional delivery systems, including emulsion-, nanoparticle,- liposome-, and hydrogel-based delivery systems, offer effective solutions for enhancing the stability and bioavailability of food-derived peptides during storage, processing, and absorption after ingestion.

For such applications, the carriers are engineered to respond dynamically to environmental triggers, including pH changes, temperature fluctuations, enzymatic activity, light exposure, ultrasound, and magnetic fields. These systems represent a significant advancement in peptide delivery, which is particularly beneficial for therapeutic applications requiring localized or targeted delivery, such as inflamed or cancerous tissues.

The introduction of PA and APP as flame retardants acted as an acid source to form phosphorus-containing carbon layers on the surface of the fiber to achieve flame retardant effect.
