An innovative colorimetric sensing strategy was developed for the detection of glucose by the integration of glucose aptamer, glucose oxidase (GOx), and horseradish peroxidase (HRP), termed aptamer proximal enzyme cascade reactions (APECR). In the presence of glucose, aptamer binding enables GOx to catalyze glucose oxidation into HO efficiently. Subsequently, the adjacent HRP catalyzes the oxidation of the peroxidase substrate, 2,2'-biazobis(3-ethylbenzothiazoline-6-sulfonic acid) (ABTS), utilizing the generated HO, resulting in a distinct color change.

Autophagy-targeted Pt(IV) agents: a new horizon in antitumor drug development.

Dalton Trans

January 2025

Institute of Biopharmaceutical Research, Liaocheng University, Liaocheng 252059, P. R. China.

Pt(IV) complexes as prodrugs of Pt(II) drugs exhibit numerous advantages such as enhanced stability, reduced toxicity, increased oral bioavailability, and efficacy in overcoming the drug resistance of Pt(II) compounds, which underscore their significant potential in the advancement of novel Pt anticancer agents. Furthermore, protective autophagy is pivotal in sustaining tumor cell homeostasis and modulating the tumor microenvironment (TME), thereby representing a critical target for the development of antitumor drugs. Specific inhibition or activation of autophagy during chemotherapy would break the internal homeostasis in the TME and increase antitumor activities.

Stabilizing Lattice Oxygen of Bi2O3 by Interstitial Insertion of Indium for Efficient Formic Acid Electrosynthesis.

Angew Chem Int Ed Engl

January 2025

University of Electronic Science and Technology of China, State Key Laboratory of Electronic Thin Films and Integrated Devices, No. 2006, Xiyuan Avenue, High-tech Zone (West Area), 610054, Chengdu, CHINA.

Bismuth oxide (Bi2O3) emerges as a potent catalyst for converting CO2 to formic acid (HCOOH), leveraging its abundant lattice oxygen and the high activity of its Bi-O bonds. Yet, its durability is usually impeded by the loss of lattice oxygen causing structure alteration and destabilized active bonds. Herein, we report an innovative approach via the interstitial incorporation of indium (In) into the Bi2O3, significantly enhancing bond stability and preserving lattice oxygen.

June 2025

State Key Laboratory of Resource Insects, Key Laboratory for Sericulture Biology and Genetic Breeding, Ministry of Agriculture and Rural Affairs, College of Sericulture, Textile and Biomass Sciences, Yibin Academy, Southwest University, Chongqing 400715, China.

Systemic administration of methotrexate (MTX), widely regarded as one of the most effective treatments for psoriasis, poses significant challenges due to its high toxicity, limited solubility, and potential for adverse effects. Consequently, developing a topical form of MTX may offer a safer and more effective strategy for psoriasis management. Silk fibroin (SF), a protein-based biomacromolecule, has shown considerable promise as a nanocarrier for sustained and targeted drug delivery, owing to its exceptional physicochemical and biological properties.

Solar-driven CO photoreduction holds promise for sustainable fuel and chemical productions, but the complex proton-coupled multi-electron transfer processes and sluggish oxidation half-reaction kinetics substantially hinder its efficiency. Here, we devised a rational catalyst design to address these challenges by fabricating ferrocene carboxylic acid-functionalized CsSbBr nanocrystals (CSB-Fc NCs), which facilitate simultaneous benzyl alcohol oxidation and CO reduction reactions under visible-light irradiation. The synchronized proton-coupled electron transfer processes between the reduction and oxidation half-reactions on CSB-Fc NCs resulted in a 5-fold increase in the CO reduction rate (45.

Multiscale Mechanical Study of Proanthocyanidins for Recovering Residual Stress in Decellularized Blood Vessels.

Adv Healthc Mater

January 2025

Key Laboratory of Biorheological Science and Technology (Chongqing University), Ministry of Education, State and Local Joint Engineering Laboratory for Vascular Implants, College of Bioengineering, Chongqing, 400044, P. R. China.

Decellularized artificial blood vessels prepared using physical and chemical methods often exhibit limitations, including poor mechanical performance, susceptibility to inflammation and calcification, and reduced patency. Cross-linking techniques can enhance the stiffness, as well as anti-inflammatory and anti-calcification properties of decellularized vessels. However, conventional cross-linking methods fail to effectively alleviate residual stress post-decellularization, which significantly impacts the patency and vascular remodeling following the implantation of artificial vessels.

Senescent bone tissue displays a pathological imbalance characterized by decreased angiogenesis, disrupted bioelectric signaling, ion dysregulation, and reduced stem cell differentiation. Once bone defects occur, this pathological imbalance makes them difficult to repair. An innovative synergistic therapeutic strategy is utilized to reverse these pathological imbalances via a conductive hydrogel doped with magnesium ion (Mg)-modified black phosphorus (BP).

Neurotransmitters are increasingly recognized to play important roles in limiting anti-tumor immunity. N-acetyl-aspartyl-glutamate (NAAG) has been extensively studied in neurological disorders; however, its potential role in restricting anti-tumor immunity has not been investigated. Here, we demonstrated that NAAG or its synthetase RimK-like family member B (RIMKLB) significantly disrupted anti-tumor immunity by rewiring the myeloid progenitor differentiation of polymorphonuclear myeloid-derived suppressor cells (PMN-MDSCs), which in turn promoted breast cancer growth and metastasis.
