Bioproduction of Gold Nanoparticles for Photothermal Therapy

Therapeutic Delivery, 2016
Photothermal response of plasmonic nanomaterials can be utilized for a number of therapeutic applications such as the ablation of solid tumors.Gold nanoparticles were prepared using different methods. After optimization, we applied an aqueous plant extract as the reducing and capping agent of gold and maximized the near-infrared absorption (650-900 nm).

Plasmonic Nanopowders for Photothermal Therapy of Tumors

Langmuir, 2012
We describe a novel strategy for the fabrication of plasmonic nanopowders (dried gold nanoparticles) by using wet chemical nanoparticle synthesis, PEG-SH functionalization, and a standard freeze-drying technique. Our strategy is illustrated by successful fabrication of different plasmonic nanopowders, including gold nanorods, gold-silver nanocages, and

Self‐Regenerating Photothermal Agents for Tandem Photothermal and Thermodynamic Tumor Therapy

Small Methods
AbstractSmall molecule‐based photothermal agents (PTAs) hold promising future for photothermal therapy; however, unexpected inactivation exerts negative impacts on their application clinically. Herein, a self‐regenerating PTA strategy is proposed by integrating 2,2′‐azino‐bis(3‐ethylbenzothiazoline‐6‐sulfonic acid) radical cation (ABTS•+) with a ...

Photothermal amplified multizyme activity for synergistic photothermal-catalytic tumor therapy

Journal of Colloid and Interface Science
Nano-enzymatic catalytic therapy has been widely explored as a promising tumor therapeutic method with specific responsiveness to the tumor microenvironment (TME). However, the inherent lower and simplex catalytic efficiency impairs their anti-tumor efficacy.
