Even if the therapy is effective, serious adverse effects might develop due to the low specificity and selectivity of antineoplastic agents. Mesoporous silica nanoparticles (MSNs) are promising materials for tumor-targeting and drug-delivery due to their small size, relatively inert nature, and extremely large specific surfaces that can be functionalized by therapeutic and targeting entities. We aimed to create a fluorescently labeled MSN-based drug-delivery system and investigate their internalization and drug-releasing capability in drug-sensitive MCF-7 and P-glycoprotein-overexpressing multidrug-resistant MCF-7 KCR cancer cells.Methods and Results: To track the uptake and subcellular distribution of MSNs, particles with covalently coupled red fluorescent Rhodamine B (RhoB) were produced (RhoB@MSNs). Both MCF-7 and MCF-7 KCR cells accumulated a significant amount of RhoB@MSNs. The intracellular RhoB@MSN concentrations did not differ between sensitive and multidrug-resistant cells and were kept at the same level even after cessation of RhoB@MSN exposure. Although most RhoB@MSNs resided in the cytoplasm, significantly more RhoB@MSNs co-localized with lysosomes in multidrug-resistant cells compared to sensitive counterparts. To examine the drug-delivery capability of these particles, RhoB@Rho123@MSNs were established, where RhoB-functionalized nanoparticles carried green fluorescent Rhodamine 123 (Rho123) -a P-glycoprotein substrate - as cargo within mesopores. Significantly higher Rho123 fluorescence intensity was detected in RhoB@Rho123@MSN-treated multidrug-resistant cells than in free Rho123-exposed counterparts. The exceptional drug-delivery potential of MSNs was further verified using Mitomycin C (MMC)-loaded RhoB@MSNs (RhoB@MMC@MSNs). Exposures to RhoB@MMC@MSNs significantly decreased the viability not only of drug-sensitive but of multidrug-resistant cells and the elimination of MDR cells was significantly more robust than upon free MMC treatments.Conclusion: The efficient delivery of Rho123 and MMC to multidrug-resistant cells via MSNs, the amplified and presumably prolonged intracellular drug concentration, and the consequently enhanced cytotoxic effects envision the enormous potential of MSNs to defeat multidrug-resistant cancer.}, year = {2022}, eissn = {1178-2013}, pages = {3079-3096}, orcid-numbers = {Igaz, Nóra/0000-0003-1580-4397; Papp, Csaba Gergő/0000-0003-4450-0667; Rónavári, Andrea/0000-0001-7054-0975; Kónya, Zoltán/0000-0002-9406-8596; Csontné Kiricsi, Mónika/0000-0002-8416-2052} } @article{MTMT:32922861, title = {Visible LED-light driven photocatalytic degradation of organochlorine pesticides (2,4-D & 2,4-DP) by Curcuma longa mediated bismuth vanadate}, url = {https://m2.mtmt.hu/api/publication/32922861}, author = {Chawla, Harshita and Garg, Seema and Rohilla, Jyoti and Szamosvölgyi, Ákos and Efremova, Anastasiia and Szenti, Imre and Ingole, Pravin Popinand and Sápi, András and Kónya, Zoltán and Chandra, Amrish}, doi = {10.1016/j.jclepro.2022.132923}, journal-iso = {J CLEAN PROD}, journal = {JOURNAL OF CLEANER PRODUCTION}, volume = {367}, unique-id = {32922861}, issn = {0959-6526}, year = {2022}, eissn = {1879-1786}, orcid-numbers = {Chawla, Harshita/0000-0003-1114-9372; Garg, Seema/0000-0002-0045-557X; Sápi, András/0000-0001-6557-0731; Kónya, Zoltán/0000-0002-9406-8596} } @article{MTMT:32907147, title = {Turning CO2 to CH4 and CO over CeO2 and MCF-17 supported Pt, Ru and Rh nanoclusters – Influence of nanostructure morphology, supporting materials and operating conditions}, url = {https://m2.mtmt.hu/api/publication/32907147}, author = {Malik, Ali Shan and Bali, Henrik and Czirok, Fanni and Szamosvölgyi, Ákos and Halasi, Gyula and Efremova, Anastasiia and Šmíd, Břetislav and Sápi, András and Kukovecz, Ákos and Kónya, Zoltán}, doi = {10.1016/j.fuel.2022.124994}, journal-iso = {FUEL}, journal = {FUEL}, volume = {326}, unique-id = {32907147}, issn = {0016-2361}, year = {2022}, eissn = {1873-7153}, orcid-numbers = {Halasi, Gyula/0000-0003-0195-9400; Sápi, András/0000-0001-6557-0731; Kukovecz, Ákos/0000-0003-0716-9557; Kónya, Zoltán/0000-0002-9406-8596} } @article{MTMT:32893026, title = {Conversion Study on the Formation of Mechanochemically Synthesized BaTiO3}, url = {https://m2.mtmt.hu/api/publication/32893026}, author = {Kozma, Gábor and Lipták, Kata and Deák, Cora and Rónavári, Andrea and Kukovecz, Ákos and Kónya, Zoltán}, doi = {10.3390/chemistry4020042}, journal-iso = {CHEMISTRY}, journal = {CHEMISTRY}, volume = {4}, unique-id = {32893026}, abstract = {Mechanochemistry is a method that can cover the energy demand of reaction pathways between solid materials. This requires enough energy to maintain the reactions between the starting materials. This is called “high-energy milling”. In our case, a planetary ball mill provided the required energy. Using the Burgio-equation, the required energy is determinable; the energy released during a single impact of a milling ball (Eb), as well as during the whole milling process (Ecum). The aim of this work was the one-step production of BaTiO3 from BaO and TiO2 starting materials. Whereas during mechanochemical reactions it is possible to produce nanoparticles of up to 10 nm, the essence of this study is to develop the preparation of BaTiO3 with a perovskite structure even without subsequent heat treatment, since sintering at high temperatures is associated with a rapid increase in the size of the particles. By describing the synthesis parameters and their energy values (Eb and Ecum), it is possible to transpose experimental conditions, so that in the case of other types of planetary ball mills or grinding vessel made of other materials, the results can be used. In this study, the mechanical treatment was carried out with a Fritsch Pulverisette-6 planetary ball mill and the transformation of the starting materials was investigated by X-ray diffractometric, Raman and Energy-dispersive X-ray spectroscopic, and transmission electron microscopic measurements.}, year = {2022}, eissn = {2624-8549}, pages = {592-602}, orcid-numbers = {Kozma, Gábor/0000-0003-2033-0720; Lipták, Kata/0000-0002-6611-2529; Rónavári, Andrea/0000-0001-7054-0975; Kukovecz, Ákos/0000-0003-0716-9557; Kónya, Zoltán/0000-0002-9406-8596} } @article{MTMT:32891371, title = {Interfacial Ni active sites strike solid solutional counterpart in CO2 hydrogenation}, url = {https://m2.mtmt.hu/api/publication/32891371}, author = {Szamosvölgyi, Ákos and Rajkumar, T. and Sápi, András and Szenti, Imre and Ábel, Marietta and Gomez Perez, Juan Fernando and Baán, Kornélia and Fogarassy, Zsolt and Dodony, Erzsébet and Pécz, Béla and Garg, Seema and Kiss, János and Kukovecz, Ákos and Kónya, Zoltán}, doi = {10.1016/j.eti.2022.102747}, journal-iso = {ENVIRON TECH INNOV}, journal = {ENVIRONMENTAL TECHNOLOGY & INNOVATION}, volume = {27}, unique-id = {32891371}, issn = {2352-1864}, year = {2022}, eissn = {2352-1864}, orcid-numbers = {Sápi, András/0000-0001-6557-0731; Gomez Perez, Juan Fernando/0000-0002-2736-2015; Fogarassy, Zsolt/0000-0003-4981-1237; Pécz, Béla/0000-0002-4651-6972; Garg, Seema/0000-0002-0045-557X; Kukovecz, Ákos/0000-0003-0716-9557; Kónya, Zoltán/0000-0002-9406-8596} }
