Abstract Different approaches have been developed for the synthesis of various nanostructured materials with unique morphologies. This study demonstrated photocatalytic and antimicrobial abilities silver-loaded zinc oxide nanocomposites (Ag@ZnO NCs). Initially, ZnO a mesoporous ellipsoidal morphology in size range 0.59 ± 0.11 × 0.33 0.09 µm (length width) was synthesized using aqueous precipitation mild hydrothermal condition (80 °C) fruit extract goji berry (GB) (as an additive) calcined air at 200 °C/2 h 250 °C/3 h. Powder X-ray diffraction (XRD) revealed formation hexagonal phase wurtzite (WZ) structure. The average crystallite 23.74 4.9 nm as calculated Debye–Scherrer’s equation.

Nanomaterials in Antibacterial Photodynamic Therapy and Antibacterial Sonodynamic Therapy

Advanced Functional Materials, Год журнала: 2024, Номер 34(38)

Опубликована: Апрель 27, 2024

Abstract Antibacterial photodynamic therapy (aPDT) and antibacterial sonodynamic (aSDT) utilize sensitizers (photosensitizers/sonosensitizers) to produce reactive oxygen species (ROS) for treatment under the stimulation of light/ultrasound, which have characteristics broad‐spectrum properties, low drug‐resistance, effective targeting infected tissues. Nanomaterials in aPDT/aSDT are primarily used as nano‐sensitizers or nano‐carriers sensitizers. They enhance stability permeability sensitizers, improve strengthen photodynamic/sonodynamic properties (modification absorption efficiency light/ultrasonic response stress by modulation nanoparticle shape, size, structure). Also, they modifiability (controlling release rate time sensitizer needed optimize therapeutic effect), programmability multifunctionality (flexible application nanotechnology designing with multiple functions, such drug delivery, targeted therapy, monitoring), expand possibilities combination therapies (the can be loaded other agents, enabling therapies). expected further promote development achieve improved effects. This review summarizes progress nanomaterials recent years based on current strategies provide a theoretical reference aPDT/aSDT.
