High-entropy alloy (HEA) represents innovative frontier in catalysis, which offers many advantages originated from its multiple metals and structural attributes. Herein, a PtRhCoNiMn nanodendritic HEA (NDHEA) was synthesized by a simplified one-pot oil-phased co-reduction method, as evidenced by a set of characterization techniques. The resulting catalyst significantly reduced the reliance on costly Pt while achieving exceptional catalytic performance, as certificated by hydrogenation of 4-nitrophenol (4-NP) and Cr (VI) as proof-of-concept models, showing normalized rate constant (k) values of 5.

Z-DNA binding protein 1 (ZBP1) has emerged as a critical pathogen-sensing protein that upon activation, triggers necroptotic signaling cascades, leading to a potent inflammatory response and potentially causing significant tissue damage. However, available drugs specifically developed for the effective inhibition or degradation of ZBP1 is still lacking so far. In this study, we developed a potent covalent recognition-based PROTAC (C-PROTAC) molecule for the degradation of ZBP1.

In this paper, a PAA-Fe-IL ionohydrogel (poly(acrylic acid)-Fe-ionic liquid ionohydrogel) with excellent mechanical and conductive properties is prepared by simple free radical polymerization. The presence of metal-ligand crosslinking within the ionohydrogel improves the mechanical properties of the hydrogel.

However, the development of a red or near-infrared light-driven efficient CO release strategy is still challenging due to the limited physicochemical characteristics of the photoactivated carbon monoxide-releasing molecules (photoCORMs). Here, we discovered a novel photorelease CO mechanism that involved dual pathways of CO release via photosensitization.

However, traditional phenotypic screening methods typically require several days of experimental cycles and lack visual confirmation of a drug's ability to inhibit viral infection. Here, we report a robust method that utilizes quantum-dot-based single-virus tracking and machine learning to generate unique single-virus infection fingerprint data from viral trajectories and detect the dynamic changes in viral movement following drug administration.

Influenza virus (IV) infection currently poses a serious and continuing threat to the global public health. Developing effective prevention strategies is important to defend against infection and spread of IV. Here, we developed a triple-protective nanoshield against IV infection in the lungs, formed by self-assembling DSPE-PEG amphiphilic polymers encapsulating the flu-preventive antiviral drug Arbidol internally.

Understanding the mechanisms of dynein-driven transport is significant for a comprehensive understanding of IAV infection. In this work, the roles of dynactin in dynein-driven transport of IAV were quantitatively dissected using quantum dot-based single-virus tracking.

During influenza A virus (IAV) infection, MTs provide long tracks for virus trafficking toward the nucleus. However, the role of the actin cytoskeleton in IAV entry and especially the transit process is still ambiguous.

Herein, atomically dispersed ternary FeCoNb active sites were incorporated into nitrogen-doped honeycomb-like mesoporous carbon (termed FeCoNb/NHC) by a two-step pyrolysis strategy, whose morphology, structure and size were characterized by a set of techniques. Further, the catalytic activity and reusability of the as-prepared FeCoNb/NHC were rigorously examined by using 4-NP catalytic hydrogenation as a proof-of-concept model.
