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.

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 ...

A Protein‐Binding Molecular Photothermal Agent for Tumor Ablation

Angewandte Chemie International Edition, 2021
AbstractPhotothermal therapy usually requires a high power density to activate photothermal agent for effective treatment, which inevitably leads to damage to normal tissues and inflammation in tumor tissues. Herein, we rationally design a protein‐binding strategy to build a molecular photothermal agent for photothermal ablation of tumor.

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 ...

Cu7.2S4 nanocrystals: a novel photothermal agent with a 56.7% photothermal conversion efficiency for photothermal therapy of cancer cells

Nanoscale, 2014
Copper sulphides, as a novel kind of photothermal agent for photothermal therapy (PTT) of cancer cells, have attracted increasing attention in recent years due to good photostability, synthetic simplicity, low toxicity and low cost. However, the unsatisfactory photothermal conversion efficiency of copper sulphides limits their bioapplication as PTT ...

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

Multifunctional Ultrasound Contrast Agents for Imaging Guided Photothermal Therapy

Bioconjugate Chemistry, 2014
Among all the imaging techniques, ultrasound imaging has a unique advantage due to its features of real-time, low cost, high safety, and portability. Ultrasound contrast agents (UCAs) have been widely used to enhance ultrasonic signals. One of the most exciting features of UCAs for use in biomedicine is the possibility of easily putting new ...

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.
