The adsorption of NOM onto mineral NPs is a key natural process, which has significant effects on the fate and biogeochemical cycles of many chemicals including toxic ones. For the first time, complex of complimentary analytical methods including capillary zone electrophoresis (CZE), dynamic light scattering, and laser Doppler velocimetry (LDV) has been used for study of effect of NOM on the fate of natural NPs in simulated surface waters. Muscovite NPs and fulvic acid (FA) have been taken as examples. It has been demonstrated that CZE can be an efficient tool for the study on interactions of mineral NPs and FA. CZE allowed one to discriminate muscovite NPs, FA, and products of their interaction—organometallic complex. It is most likely that FA forms a complex with Al. It is found that Al<sup>3+</sup>-FA complex has an intermediate electrophoretic mobility (46.6 cm<sup>2</sup>V<sup>−1</sup> s<sup>−1</sup>) between muscovite NPs (31.6 cm<sup>2</sup>V<sup>−1</sup> s<sup>−1</sup>) and FA (49.3 cm<sup>2</sup>V<sup>−1</sup> s<sup>−1</sup>) as measured for suspension with pH value of 6. It is also demonstrated that electrophoretic mobility of Al<sup>3+</sup>-FA complex is less susceptible to pH of medium as compared to muscovite NPs. The absolute value of electrophoretic mobility increases with increasing pH of buffer solution from 31.0 to 37.9·10<sup>−5</sup> cm<sup>2</sup>V<sup>−1</sup> s<sup>−1</sup> for muscovite NPs and from 46.3 to 50.0·10<sup>−5</sup> cm<sup>2</sup>V<sup>−1</sup> s<sup>−1</sup> for Al<sup>3+</sup>-FA complex.

Globally, agriculture is a major field for nanoparticle applications, with the United States, Russia, China, India, and Iran leading in agricultural nanoparticle production. Nanoparticles are recognized as transformative technologies capable of modernizing traditional agricultural systems. The main applications of nanotechnology in agriculture include advanced agrochemical formulations, improved crop protection, and precise sensor technologies for detecting pollutants at the molecular level. Despite these promising benefits, the adoption of nanotechnology remains limited in Africa, with only a few countries, such as Egypt, South Africa, Ghana, Tunisia, and Algeria, attempting to integrate it into sectors like agriculture and healthcare. Furthermore, only a small number of African nations have established formal strategies and policies for nanotechnology. Therefore, to support Africa’s commitment to international obligations, including the Paris Climate Agreement and the African Union’s Agenda in 2063, to achieve Sustainable Development, governments must prioritize transformative policy development, encourage regional and international collaboration, and invest in education and research in nanotechnology.</p></div>","PeriodicalId":653,"journal":{"name":"Journal of Nanoparticle Research","volume":"27 5","pages":""},"PeriodicalIF":2.1,"publicationDate":"2025-05-05","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143904843","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}

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}
