The pathological aggregation of some proteins is claimed to be highly related to several human diseases, such as β‐amyloid 1–42 (Aβ42) to Alzheimer's disease (AD), islet amyloid polypeptide, and insulin to type 2 diabetes mellitus. Therefore, it is in desperate need to develop effective methods for detection of protein aggregates and inhibition of abnormal aggregation. Herein, to construct all‐in‐one...
Osteosarcoma (OS) is the most serious bone malignancy, and the survival rate has not significantly improved in the past 40 years. Thus, it is urgent to develop a new strategy for OS treatment. Chemodynamic therapy (CDT) as a novel therapeutic method can destroy cancer cells by converting endogenous hydrogen peroxide (H2O2) into highly toxic hydroxyl radicals (·OH). However, the therapeutic efficacy...
Tuning the electronic structures of mesocrystals at the atomic level is an effective approach to obtaining unprecedented properties. Here, a lattice‐confined strategy to obtain isolated single‐site Sn atoms in CuO mesocrystals to improve catalytic performance is reported. The Sn/CuO mesocrystal composite (Sn/CuO MC) has ordered Sn–O–Cu atomic interfaces originated from the long‐range ordering of the...
Adjusting the local coordination environment of single‐atom electrocatalysts is a viable way to improve catalytic performance. The diversity of coordination geometric structures is limited to the traditional in‐plane configuration, with only a little consideration paid to out‐of‐plane configurations due to the lack of suitable carriers and fabrication methods. This study reports out‐of‐plane coordination...
Flexible organic near‐infrared (NIR) phototransistors hold promising prospects for potential applications such as noninvasive bioimaging, health monitoring, and biometric authentication. For integrated circuits of high‐performance devices, organic single‐crystalline micro‐/nanostructures with precise positioning are prominently anticipated. However, the manufacturing of organic single‐crystalline...
It is difficult to effectively treat bacterial osteomyelitis using photothermal therapy or photodynamic therapy due to poor penetration of light. Here, a microwave (MW)‐excited magnetic composite of molybdenum disulfide (MoS2) / iron oxide (Fe3O4) is reported for the treatment of bacteria‐infected osteomyelitis. In in vitro and in vivo experiments, MoS2/Fe3O4 is shown to effectively eradicate bacteria‐infected...
Spintronics and molecular chemistry have achieved remarkable achievements separately. Their combination can apply the superiority of molecular diversity to intervene or manipulate the spin‐related properties. It inevitably brings in a new type of functional devices with a molecular interface, which has become an emerging field in information storage and processing. Normally, spin polarization has...
Nanovaccine‐based immunotherapy (NBI) has the ability to initiate dendritic cell (DC)‐mediated tumor‐specific immune responses and maintain long‐term antitumor immune memory. To date, the mechanism by which the mechanical properties of nanoparticles alter the functions of DCs in NBI remains largely unclear.
