“…As shown in Figure F, the XPS spectrum of IONs@LDH showed obvious peaks of Mg 1s, O 1s, and Al 2p corresponding to LDH nanoparticles, and the peak of Fe 2p located at ∼720.0 eV can be attributed to ION nanodots. Further analysis of the Fe 2p peak determined the existence of Fe 2+ (located at 710.0 and 723.0 eV) and Fe 3+ (located at 712.6 and 725.2 eV) in the IONs@LDH, , which is similar to free IONs (Figure S5).…”

The upregulation of dihydroorotate dehydrogenase (DHODH) redox systems inside tumor cells provides a powerful shelter against lipid peroxidation (LPO), impeding ferroptosis-induced antitumor responses. To solve this issue, we report a strategy to block redox systems and enhance ferroptotic cancer cell death based on a layered double hydroxide (LDH) nanoplatform (siR/IONs@LDH) co-loaded with ferroptosis agent iron oxide nanoparticles (IONs) and the DHODH inhibitor (siR). siR/IONs@LDH is able to simultaneously release IONs and siR in a pH-responsive manner, efficiently generate toxic reactive oxygen species (ROS) via an Fe 2+ -mediated Fenton reaction, and synergistically induce cancer cell death upon the acceleration of LPO accumulation. In vivo therapeutic evaluations demonstrate that this nanomedicine has excellent performance for tumor growth inhibition without any detectable side effects. This work thus provides a new insight into nanomaterial-mediated tumor ferroptosis therapy.

The latest developments in the adsorption of organic dyes by adsorbents (metal oxides, modified metal oxides) were addressed in this review study. The main goal of this paper is to sort out the dispersion information of adsorbent materials, which are often employed in organic dye adsorption. The review dedicated to the specific dyes adsorption using various adsorbent (metal oxides, modified metal oxides). The review covers the adsorption process including parameters, kinetics, and isotherms. The review gives the brief information of Congo red (CR) adsorption using metal oxide nano‐adsorbents which provide readers with massive dye specific collection. For the first time, several metal‐doped materials that absorb organic dyes are summarized and addressed. The review includes adsorption of organic dyes using single metal oxide, bimetallic oxide, trimetallic oxide, and modified metal oxide. This study also summarized the effects of critical factors such as pH, initial dye concentration, adsorbent dosage, contact time, and temperature on dye adsorption utilizing metal oxide nano‐adsorbents. In addition, the kinetic and applied isotherm models have been discussed. Finally, a few recommendations are made for further research on adsorbent materials.

“…In a previous study, we made magnetic microrobots with iron (II, III) oxide nanoparticles (Fe 3 O 4 NPs) based on hydrocarbondegrading bacteria (Pi et al, 2022). The magnetic microrobot performed excellently for Congo red adsorption from the aquatic phase (Pi et al, 2022).…”

Removing fluoroquinolones (FQs) in marine culture tailwater is crucial for the coastal marine environment. The application of a bacteria-based microrobot for FQ removal was discussed. Norfloxacin (NOR) and levofloxacin (LEV) had static maximum adsorption capacities of 114.8 and 49.4 mg/g, respectively, by a magnetic microrobot. The experimental results of NOR adsorption by a magnetic microrobot were well supported by the Langmuir isotherm and Elovich kinetic models. Both the Langmuir isotherm model and the pseudo-second-order kinetic model may be able to accurately represent the LEV adsorption process. The mass transfer mechanism of the NOR and LEV adsorptions was divided into two steps and described better using the intraparticle diffusion (IPD) model. The exothermic and spontaneity of the sorption process were demonstrated through the study of thermodynamics. The magnetic microrobot’s heterogeneous surface was validated by the examination of site energy distribution. Additionally, this study demonstrated that the majority of the NOR and LEV sorption took place at sites with energies over 4.25 and 17.36 kJ/mol, respectively, supporting the notion that NOR and LEV adsorption constitute physical–chemical processes. Based on the above results, a magnetic microrobot, as a new-style green bio-adsorbent, can potentially be used to remove NOR and LEV from the mariculture in an inexpensive and effective manner.
