An MRI‐Sensitive, Non‐Photobleachable Porphysome Photothermal Agent

Angewandte Chemie International Edition, 2014
AbstractPhotothermal therapy makes use of photothermal sensitizers and laser light to thermally ablate diseased tissues. Porphysome nanoparticles offer a nontoxic alternative to inorganic nanocrystals for the efficient conversion of light into heat.

Carbon Nanohorns as Photochemical and Photothermal Agents

ASME 2009 Summer Bioengineering Conference, Parts A and B, 2009
Laser therapies based on photochemical or photothermal mechanisms can provide a minimally invasive and potentially more effective treatment alternative to conventional surgical resection procedures by delivering prescribed optical/thermal doses to a targeted tissue volume with minimal damage to intervening and surrounding tissues. However laser therapy

Advances of Photothermal Agents with Fluorescence Imaging/Enhancement Ability in the Field of Photothermal Therapy and Diagnosis

Molecular Pharmaceutics
Photothermal therapy (PTT) is an effective cancer treatment method. Due to its easy focusing and tunability of the irradiation light, direct and accurate local treatment can be performed in a noninvasive manner by PTT. This treatment strategy requires the use of photothermal agents to convert light energy into heat energy, thereby achieving local ...

Perylenediimide chromophore as an efficient photothermal agent for cancer therapy

Science Bulletin, 2018
Photothermal agents with improved bioavailabilities can generate heat from near-infrared light, which has been efficiently used for in vivo photothermal therapy (PTT) for cancer, with minimum tissue invasion. Strategies for developing organic near-infrared-absorbing molecules for photothermal cancer therapy have drawn intensive attention among academic

Single walled carbon nanohorns as photothermal cancer agents

Lasers in Surgery and Medicine, 2011
AbstractBackgroundNanoparticles have significant potential as selective photo‐absorbing agents for laser based cancer treatment. This study investigates the use of single walled carbon nanohorns (SWNHs) as thermal enhancers when excited by near infrared (NIR) light for tumor cell destruction.MethodsAbsorption spectra of SWNHs in deionized water at ...

PEGylated Copper Nanowires as a Novel Photothermal Therapy Agent

ACS Applied Materials & Interfaces, 2016
Metal nanowires are promising for their applications including electrical connectors, transparent conductive electrodes and conductive additives, but the use of metal nanowires as photothermal agents to convert light to heat has yet to be reported.

A Golgi Apparatus‐Targeted Photothermal Agent with Protein Anchoring for Enhanced Cancer Photothermal Therapy

Advanced Healthcare Materials
AbstractThe Golgi apparatus (GA) is central in shuttling proteins from the endoplasmic reticulum to different cellular areas. Therefore, targeting the GA to precisely destroy its proteins through local heat could induce apoptosis, offering a potential avenue for effective cancer therapy.

Dissolving Microneedle Patches Integrating Optical Clearing and Photothermal Agents for Improved Photothermal Disinfection

Macromolecular Bioscience
AbstractPhotothermal disinfection is an emerging and efficient therapeutic method for treating various infections. However, the therapeutic efficacy is hindered by the poor tissue penetration of light. While tissue optical clearance technology can enhance light transmission, the stratum corneum impedes the delivery of clearing agents to deeper tissues.

A Ferrocene-Based Supramolecular Photothermal Agent for Enhanced Photothermal/Ferroptosis Therapy and Immune Activation

Biomacromolecules
Photothermal therapy (PTT) is impeded by limited light penetration depth and cellular heat resistance induced by overexpressed heat shock proteins. Herein, we propose a ferrocene (Fc)-based supramolecular photothermal agent (PTA) to improve the therapeutic efficacy.
