Future Radiation Therapy: Photons, Protons and Particles
Future Oncology, 2013Radiation therapy plays a critical role in the current management of cancer patients. The most common linear accelerator-based treatment device delivers photons of radiation. In an ever more precise fashion, state-of-the-art technology has recently allowed for both modulation of the radiation beam and imaging for this treatment delivery.

Recent Advances in Two-Photon Photodynamic Therapy
Anti-Cancer Agents in Medicinal Chemistry, 2008Photodynamic therapy (PDT) is a treatment for tumors and accepted in several countries in the world. Introduction of two-photon absortion (2PA) into PDT allows spatially selective treatment of cancers. Possibilities and limitations of the use of two-photon excitation in PDT are discussed, and many literatures in this area are reviewed.

Molecular photosensitisers for two-photon photodynamic therapy
Chemical Communications, 2017With the recent development of clinical two-photon microscopes or endoscopes, new photosensitisers for two-photon photodynamic therapy are the subject of increasing interest. Herein, we review the advances within the ten last years of molecular two-photon photosensitisers.

It is suggested here that significant advantages should accrue from the use of 40 keV photons from implanted sources of 145Sm. These energies should stimulate Auger electron cascades from IdUrd, as well as produce non-repairable damage from radiosensitization.

Photon-beam radiation therapy and Monte Carlo
Computing in Science & Engineering, 2000Because small variations in radiation doses can cause significant changes in clinical outcome, the calculation accuracy is a major factor in the success or failure of a cancer treatment course. This article describes how stochastic, Monte Carlo radiation transport methods can predict radiation doses for cancer patients.

Journal of Colloid and Interface Science
Photodynamic therapy (PDT) offers potential for combating bacterial infections through the generation of reactive oxygen species (ROS). However, the antibacterial efficiency of PDT is largely impeded by the limited photon absorption of photosensitizers and the short diffusion length and lifespan of ROS.

Photonic metallic nanostructures in photodynamic therapy
SPIE Proceedings, 2009ABSTRACT Plasmons are resonant modes that involve the interaction between free charges and light. Nanoparticle-based photonic explorers have been developed for photodynamic therapy (PDT). PDT has been widely used in both oncological (e.g., tumors) and nononcological (e.g., age-related macular degeneration, localized infection, and nonmalignant skin ...

Applied photonic therapy in veterinary medicine
SPIE Proceedings, 2005There can be no question that specific systemic physiological results occur, when red light (660nm) is applied to the skin, it is now more a question of detailed mechanisms. Before gathering statistically signifcant clinical trial data, it is important to first enumerate the type of results observed in practice.

Two-photon photodynamic therapy with curcumin nanocomposite
Colloids and Surfaces B: BiointerfacesTwo-photon photodynamic therapy (TP-PDT) offers an innovative approach to cancer treatment that utilizes near-infrared light to activate photosensitizers and generate reactive oxygen species (ROS) for targeted cancer cell elimination. TiO2-CUR-Sofast (TCS), which uses TiO2 nanoparticles and Sofast cationic polymer to modify curcumin (CUR), has ...
