Ni single‐atom catalysts (SACs) are appealing for electrochemical reduction CO2 reduction (CO2RR). However, regulating the balance between the activity and conductivity remains a challenge to Ni SACs due to the limitation of substrates structure. Herein, the intrinsic performance enhancement of Ni SACs anchored on quasi‐one‐dimensional graphene nanoribbons (GNRs) synthesized is demonstrated by longitudinal...
Although photodynamic immunotherapy has been promoted in the clinical practice of cholangiocarcinoma, the insensitivity to photodynamic immunotherapy remains to be a great problem. This can be largely attributed to an immune‐suppressive tumor microenvironment (TME) manifested as immature myeloid cells and exhausted cytotoxic T lymphocytes. Here, a three‐in‐one oncolytic adenovirus system PEG‐PEI‐Adv‐Catalase‐KillerRed...
Self‐Driven Near‐Infrared Photodetectors
In article number 2206262, Hao Jin, Longbiao Huang, Zhenhua Sun, and co‐workers report that bulk photovoltaic effect (BPVE) is found in the SnTe film by Si doping though breaking the inversion symmetry. As a result, additional current originated from the BPVE is generated beyond the p‐n junctions, leading to an improvement of photocurrent by 7.5 times.
The upsurge of new materials that can be used for near‐infrared (NIR) photodetectors operated without cooling is crucial. As a novel material with a small bandgap of ≈0.28 eV, the topological crystalline insulator SnTe has attracted considerable attention. Herein, this work demonstrates self‐driven NIR photodetectors based on SnTe/Si and SnTe:Si/Si heterostructures. The SnTe/Si heterostructure has...
Autophagy
To overcome the autophagy compromised mechanism of protective cellular processes by “eating” damaged organelles or potentially toxic materials in tumor cells, Nan Li and co‐workers show how tellurium double‐headed nanobullets (TeDNBs)‐HO is utilized to induce autophagy dysfunction. On the one hand, TeDNBs‐mediated endoplasmic reticulum stress could excessively induce autophagy; thus, resulting...
To overcome the autophagy compromised mechanism of protective cellular processes by “eating”/“digesting” damaged organelles or potentially toxic materials with autolysosomes in tumor cells, lysosomal impairment can be utilized as a traditional autophagy dysfunction route for tumor therapy; however, this conventional one‐way autophagy dysfunction approach is always limited by the therapeutic efficacy...
This work is inspired by oysters converting worthless sand into precious pearls. In article number 2000553, Chen Wang and co‐workers present the “trash into treasure” process, which efficiently promotes antibacterial therapy and wound healing. The confinement effect of 2D Al‐metal–organic frameworks (MOFs) maintains gold nanoparticles (AuNPs) as ultrasmall without gathering and makes them exhibit...
As one of the common reactive oxygen species, H2O2 has been widely used for combating pathogenic bacterial infections. However, the high dosage of H2O2 can induce undesired damages to normal tissues and delay wound healing. In this regard, peroxidase‐like nanomaterials serve as promising nanozymes, thanks to their positive promotion toward the antibacterial performance of H2O2, while avoiding the...
