Chemodynamic therapy (CDT) based on multifunctional nanoparticles (NPs) has occurred as an attractivecancer treatment that covers the shortage of nonnegligible limitations from single therapy. Herein, wesynthesize a safe and universal CDT nanoparticle—iron single-atom nanoparticle (Fe SANP), in whichFe single-atom as the active catalytic site is anchored in a carbon framework with encapsulated doxorubicin(DOX). Fe SANPs work as catalase-like nanozyme for hydroxyl radicals (OH) production. The preparedNPs (denoted as DOX@Fe SANPs) can efficiently mediate peroxidase-like activity with the existenceof H2O2 that enhances cancer cell elimination by generating abundant OH. DOX@Fe SANPs exhibit a pHinduceddegradable character that contributes to specific drug release in the tumor microenvironment(TME). DOX@Fe SANPs produce ignorable systematic toxicity after biodegradation and drug delivery processes. Collectively, this study highlights the efficient anti-tumor performances of the iron single-atomnanocatalysts containing an anti-cancer drug DOX.

Isobaric vapor-liquid equilibrium (VLE) data for {methanol (1)+benzene (2)+1-octyl-3-methylimidazolium tetrafluoroborate (3)} where 3 is an ionic liquid ([OMIM]+[BF4]−) at atmospheric pressure (101.32 kPa) were measured with a modified Othmer still. The results showed that the ionic liquid studied can transfer the azeotropic point and eliminate the azeotropic phenomena when its concentration is up to x3=0.30. This means that [OMIM]+[BF4]− can be used as a promising entrainer in the application of extractive distillation. The measured ternary data were correlated using the NRTL model.
