Dual‐Physical‐Field Nanocatalysis: Injectable Hydrogel Enables Piezo‐Photothermal Synergy for Breast Cancer Therapy

Advanced Science, EarlyView.
ABSTRACT Piezocatalytic therapy (PCT) harnesses mechanical energy to generate tumor‐lethal reactive oxygen species (ROS), but its efficacy is limited by rapid electron‐hole recombination and poor intratumoral retention. To overcome these limitations, we engineered heterostructured BiOCl@CuO nanosheets embedded in an injectable, conductive ...

Dependence of Ultrasonic and Magnetic Hyperthermia on the Concentration of Magnetic Nanoparticles [PDF]

Acta Physica Polonica A, 2018
Hyperthermia treatment is the heating of tumor tissue up to temperatures between 41 ºC and 45 ºC, which trigger several physiological reactions in the body. Hyperthermia within tissue can be applied through various mechanisms. One of them is magnetic hyperthermia which uses superparamagnetic iron oxide nanoparticles (SPIONs) heated by an externally ...

Spatial focusing of magnetic particle hyperthermia

Nanoscale Advances, 2020
Magnetic particle hyperthermia is a promising cancer therapy, but a typical constraint of its applicability is localizing heat solely to malignant regions sparing healthy surrounding tissues.

A Novel Approach Based on Acceptor–Donor–Acceptor Type Molecules Enhances the Therapeutic Efficacy and Safety of Photothermal Therapy for Osteosarcoma

Advanced Science, EarlyView.
Jin et al. developed IEICO‐F nanoparticles with enhanced photothermal conversion efficiency via optimized push‐pull effect. Under 808 nm laser, these nanoparticles effectively generated heat to kill osteosarcoma cells and exhibited significant tumor suppression in vivo. Therefore, this novel A‐D‐A type molecule‐based photothermal therapy strategy holds

Biologically Targeted Magnetic Hyperthermia: Potential and Limitations [PDF]

Frontiers in Pharmacology, 2018
Hyperthermia, the mild elevation of temperature to 40-43°C, can induce cancer cell death and enhance the effects of radiotherapy and chemotherapy. However, achievement of its full potential as a clinically relevant treatment modality has been restricted by its inability to effectively and preferentially heat malignant cells.

Scaffolds functionalized with matrix metalloproteinase-responsive release of miRNA for synergistic magnetic hyperthermia and sensitizing chemotherapy of drug-tolerant breast cancer

Bioactive Materials
Combining hyperthermia and chemotherapy for maximum anticancer efficacy remains a challenge because drug-tolerant cancer cells often evade this synergistic treatment due to drug resistance and asynchronous drug release.

Quantum Photothermal Self‐Monitoring Fiber Probes for In Vivo Photothermal Therapy

Advanced Science, EarlyView.
A miniaturized quantum photothermal fiber probe based on a metal/polymer/glass composite optoelectronic fiber that simultaneously guides lightwave and microwave was developed for the first time. The probe achieves enhanced photothermal conversion (13°C/mW, 25°C–120°C range) while providing real‐time self‐monitoring with 0.2°C thermal resolution at the ...
