Photosensitizing Activity of Nanoparticles of Poly (2-amino phenol)/Gold for Intensified Doxorubicin Therapeutic Effect on Melanoma Cancer Cells under Synergism Effect of 808-nm Light.

Background: Photothermal therapy (PTT) is one of the effective and non-invasive strategies which hold great promise for improving the treatment of cancer cells. PTT is based on activating a photosensitizer by infrared light irradiation and producing heat and reactive species and apoptosis in the tumor area.

Objective: The aim of this study was to investigate the effect of photothermal/chemotherapy on melanoma cancer cells using poly (2-amino phenol)/gold (P2AO/AuNPs) and doxorubicin (DOX).

Antibacterial and anti-biofilm activities of gold-curcumin nanohybrids and its polydopamine form upon photo-sonotherapy of Staphylococcus aureus infected implants: In vitro and animal model studies.

Implant-related infections are among the major post-surgery problems, and treatment of these infections is challenging due to the formation of biofilms by microorganisms such as Staphylococcus aureus. Herein, a novel gold-curcumin nanohybrid (GCNH) was synthesized for the first time and characterized. GCNH had a band gap energy of 2.

A Study of Sonodynamic Therapy of Melanoma C540 Cells in Vitro by Titania/Gold Nanoparticles.

Background: Sonodynamic Therapy (SDT), a safe and non-invasive strategy in tumor therapy, is in development using novel sono-sensitizers, activated by low-intensity ultrasound radiation. SDT mainly progresses through Reactive Oxygen Species (ROS) generation followed by cell annihilation.

Objective: The current study aimed to investigate the effect of ultrasound therapy with titania/gold nanoparticles (NPs) on melanoma cancer.
