Defect engineering is an important way to tune the catalytic properties of metal‐organic framework (MOF), yet precise control of defects is difficult to achieve. Herein, a cerium‐based MOF (CeTCPP) is decorated with Au nanoparticles. Under ultrasound irradiation, Au nanoparticles can precisely turn 1/3 of the pristine Ce3+ nodes into Ce4+. With the stable existence of Ce4+, the coordination of Ce...
Conferring catalytic defects in sonosensitizers is of paramount importance in reinforcing sonodynamic therapy. However, the formation of such 0D defects is governed by the Schottky defect principle. Herein, 2D catalytic planar defects are designed within Ti3C2 sheets to address this challenge. These specific planar slip dislocations with abundant Ti3+ species (Ti3C2‐SD(Ti3+)) can yield surface‐bound...
Wound biofilm infection has an inherent resistance to antibiotics, requiring physical debridement combined with chemical reagents or antibiotics in clinical treatment, but it is invasive and may exist as incomplete debridement. So, a new type of noninvasive and efficient treatment is needed to address this problem. Here, the crystal phase engineering of TiO2 is presented to explore the sonocatalytic...
Osteomyelitis is considered as the most serious bone infection, which can lead to the bone destruction or fatal sepsis. Clinical treatments through frequent antibiotics administration and surgical debridement bring inevitable side effects including drug‐resistance and disfigurements. It is urgent to develop an antibiotics‐free and rapid strategy to treat osteomyelitis. Herein, a bifunctional sonosensitizer...
