In situ Growth of ZIF-8 Nanoparticles on Graphene Oxide Nanosheets: A Multifunctional Nanoplatform for Combined Ion‐interference and Photothermal Therapy

In summary, highly stability and dispersed BSArGO@ZIF8 NSs were prepared by a simple electrostatic interaction method. According to the delivery effect of BSArGO@ZIF8 NSs, we found that BSArGO@ZIF8 NSs possess higher lethality to cancer cells. Furthermore, under NIR irradiation, BSArGO@ZIF8 NSs-mediated PTT could further kill cancer cells, and the increased temperature caused by photothermal conversion accelerated the Fenton reaction rate, enhancing the efficiency of BSArGO@ZIF8 NSs cell lethality. RNA-seq analysis confirmed that. BSArGO@ZIF8 NSs could promote cancer death through activate bim-mediated mitochondrial apoptotic events, induce disruption of microtubule function, loss of integrity of the nuclear membrane, DNA flagmentation, and change pro-apoptptic genes expression. Total RNA of Cal27 from 3 different experiments treated with or without BSArGO@ZIF-8 NSs at 6 h were collected and RNA-seq was used to analyze the whole genome expression at LC Sciences through the Illumina X10 platform
