Synergistic delivery of gold nanorods using multifunctional microbubbles for enhanced plasmonic photothermal therapy
Plasmonic photothermal therapy (PPTT) using plasmonic nanoparticles as efficient photoabsorbing agents has been proposed previously. One critical step in PPTT is to effectively deliver gold nanoparticles into the cells. This study demonstrates that the delivery of gold nanorods (AuNRs) can be greatly enhanced by combining the following three mechanisms: AuNRs encapsulated in protein-shell micro...
متن کاملDevelopment of functional gold nanorods for bioimaging and photothermal therapy
Gold nanorods have strong surface plasmon band at near-infrared light region, and are used as a photothermal converter. Since the near-infrared light penetrates into tissues deeply, it has been expected as a contrast agent for near infrared light bioimaging, a photosensitizer for photothermal therapy, and functional device for drug delivery system responding to near-infrared light irradiation. ...
متن کاملIntracellular pH-Induced Tip-to-Tip Assembly of Gold Nanorods for Enhanced Plasmonic Photothermal Therapy
The search for efficient plasmonic photothermal therapies using nonharmful pulse laser irradiation at the near-infrared (NIR) is fundamental for biomedical cancer research. Therefore, the development of novel assembled plasmonic gold nanostructures with the aim of reducing the applied laser power density to a minimum through hot-spot-mediated cell photothermolysis is an ongoing challenge. We de...
متن کاملMUC1-Targeted Cancer Cell Photothermal Ablation Using Bioinspired Gold Nanorods
Recent studies have highlighted the overexpression of mucin 1 (MUC1) in various epithelial carcinomas and its role in tumorigenesis. These mucins present a novel targeting opportunity for nanoparticle-mediated photothermal cancer treatments due to their unique antenna-like extracellular extension. In this study, MUC1 antibodies and albumin were immobilized onto the surface of gold nanorods usin...
متن کاملSynthesis and Evaluation of Gold Nanoparticles/Nanorods to Use in Plasmonic Photothermal Therapy
Introduction: Photothermal therapy is a method of cancer treatment that plasmonic nanoparticles are used to convert infrared light into local heat. Due to the plasmonic properties of gold nanoparticles, this compound was used as a contrast agent. The aim of this study was to synthesize gold nanoparticles with different conjugations for photothermal therapy. Methods: This research was an experi...
