The objective of this study was to enhance the solubility and bioavailability of quercetin by loading quercetin into long-circulating liposomes (Q-LL) to ultimately achieve the goal of enhancing the therapeutic impact of quercetin on DPN. The Q-LL was synthesized using the film dispersion method, followed by a comprehensive series of characterizations as well as in vitro release and in vivo pharmacokinetic studies. Subsequently, the DPN rat model was established before the administration of free quercetin and Q-LL to the rats. The potential mechanism of Q-LL in the treatment of DPN was postulated by detecting levels of blood lipid, oxidative stress, and inflammation in rats after 4 weeks of oral administration. Q-LLs were successfully developed, which had a particle size of 110.93 ± 1.49 nm, a PDI of 0.179 ± 0.012, a zeta potential of − 25.37 ± 0.31 mV, an encapsulation efficiency (EE)% of 93.57 ± 0.19%, and a drug loading (DL)% of 9.66 ± 0.12%, as well as displayed a sustained release effect. This Q-LL significantly increased the solubility and in vivo circulation time of quercetin, thus significantly improving the bioavailability of quercetin. Q-LL may alleviate DPN by reducing levels of blood lipid, oxidative stress, and inflammatory response. Overall, Q-LL may offer a new strategy for the potential extension of the in vivo circulation of quercetin and enhancement of its bioavailability for DPN treatment.</p><h3>Graphical abstract</h3>\u0000<div><figure><div><div><picture><source><img></source></picture></div></div></figure></div></div>","PeriodicalId":653,"journal":{"name":"Journal of Nanoparticle Research","volume":"27 5","pages":""},"PeriodicalIF":2.1,"publicationDate":"2025-04-28","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143879741","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"材料科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

One material that deserves to be highlighted is reduced graphite oxide (rGO) due to its excellent adsorption capacity. Among the emerging contaminants, bisphenol A (BPA) generates numerous problems for human health, such as hormonal changes, immune dysfunction, and type 2 diabetes mellitus. In this context, the adsorption of BPA and its form with an anionic oxygen and a protonated oxygen were studied to simulate the effect of pH on the adsorption process, elucidated through computational simulations using density functional theory. The binding energies (Δ<i>E</i><sub>Bind</sub>) and enthalpy variation (Δ<i>H</i>) for all complexes were less than zero, Δ<i>E</i><sub>Bind</sub> and Δ<i>H</i> < 0.00 kcal mol<sup>−1</sup>, showing that interactions can occur and that they are exothermic. The Gibbs energy values showed that only the interactions of anionic and protonated oxygen with the matrix were spontaneous. The structural parameters were identified, and the protonation or deprotonation of the BPA hydroxyl forms stronger bonds/interactions with the rGO matrix, showing a positive effect of pH on adsorption. From the analysis of the topological parameters of the quantum theory of atoms in molecules and the non-covalent interaction, it was possible to demonstrate that the interactions are electrostatic, with the exception of those that occur between the protonation or deprotonation of the BPA hydroxyl with the matrix that forms bonds. Finally, based on the theoretical results, it can be concluded that the rGO matrix can interact with BPA and that the effect of pH improves the adsorption process. Therefore, this study could support new experimental tests for removing this emerging contaminant from effluents.</p></div>","PeriodicalId":653,"journal":{"name":"Journal of Nanoparticle Research","volume":"27 5","pages":""},"PeriodicalIF":2.1,"publicationDate":"2025-04-23","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143865400","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"材料科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
