Sea urchin-like Bi₂S₃/curcumin heterojunction rapidly kills bacteria and promotes wound healing under near-infrared light

Abstract

Bacterial infection is an urgent public health problem. We design a novel photo-responsive hybrid material by growing small molecules of curcumin (Cur) in situ on a sea urchin-like Bi2S3 surface...

TCPP/MgO-loaded PLGA microspheres combining photodynamic antibacterial therapy with PBM-assisted fibroblast activation to treat periodontitis

“…Electron spin resonance spectrometer (ESR, EMXplus, Bruker, Germany) was used to detect the singlet oxygen produced by PMT using 2,2,6,6-tetramethylpiperidine (TEMP) as the spin-trapping agent. 25,26…”

“…Electron spin resonance spectrometer (ESR, EMXplus, Bruker, Germany) was used to detect the singlet oxygen produced by PMT using 2,2,6,6-tetramethylpiperidine (TEMP) as the spin-trapping agent. 25,26 2.4 In vitro release profile of Mg 2+ 2 mg PM and 2 mg PMT was separately dispersed in 2 mL PBS to prepare the PM and PMT solutions, respectively, and homogeneously mixed. Then, 1 mL supernatant was collected at 1, 2, 3, 5, 7, 14, and 20 days, respectively, in the dark condition, with 1 mL fresh PBS supplemented to replace the extracted solution.…”

The Enhanced Photocatalytic Sterilization of a Metal–Organic‐Framework‐Based S‐Scheme Heterostructure of Ag2S@PB for Rapid Healing of Bacteria‐Infected Open Wounds

“…The temperature variation of Ag 2 S@PB was also examined within three-cycle curves. The photothermal conversion rate (η) of Ag 2 S@PB is counted according to the following equation: [47] η…”

Temperature-Responsive Nanoassemblies for Self-Regulated Photothermal Therapy and Controlled Copper Release to Accelerate Chronic Wound Healing

“…7 Several outstanding smart photoresponsive antibacterial materials have been developed to control and combat bacterial infections. For example, sea urchin-like Bi 2 S 3 /curcumin heterojunction 8 and nanofiber membranes, 9 both of which use near-infrared (NIR) excitation, lead to the separation of electron−hole pairs, resulting in the synergistic effect of photothermal antibacterial and reactive oxygen species. However, a temperature self-regulating photothermal system with thermos-responsive absorption properties is more promising for precise temperature-controlled PTT with less requirement of operators.…”
