Radiation therapy is used in the treatment of almost 50% of all cancers in industrialized countries. Over the years, advances in engineering, computer technology, material sciences and biology has enabled medical physicists to devise more accurate radiation delivery systems. One of the oldest forms of radiation therapy is brachytherapy, or originally called Curiethérapie in honor of Marie...

Monte Carlo simulations are increasingly applied in medical physics to understand radiation interactions and energy deposition on sub-micron length scales within biological targets, e.g. DNA. These classical trajectory Monte Carlo simulations neglect the quantum wave nature of electrons, however, quantum effects may become non-negligible at sub-1 keV energies. In this work, quantum...

The development of a radiosensitivity predictive assay is an attractive goal in radiation oncology. Since there is a high degree of inter-patient variability in the inherent sensitivity or resistance to therapy, it is crucial to have the ability to identify molecular markers that correlate with sensitivity or resistance to radiation treatment. We have applied Raman micro-spectroscopy (RMS) in...

Photodynamic therapy (PDT) is emerging as a novel clinical approach that uses light (including laser sources) and photoactivatable compounds (photosensitizers) for the treatment of various tumors and other non-malignant conditions. PDT has potential advantages over surgery and other therapies, being minimally invasive, with accurate targeting and few side effects. However, most clinical PDT...

Photonic biosensors based on photocorrosion of GaAs/AlGaAs nano-heterostructures have been investigated as an attractive platform for low-cost and rapid detection of bacteria in aqueous environments.1, 2 Both GaAs and Al0.35Ga0.65As layers are unstable in an aqueous surrounding when illuminated with photons of energy exceeding bandgap of either of these materials. Among elements released to a...

Cisplatin is a very widely used platinum-based chemotherapy drug and is the cornerstone agent in treating a variety of cancers, including ovarian cancer, testicular cancer, cervical cancer, bladder cancer, lung cancer, head and neck cancer, lymphoma, and brain tumors. It is one of the few curative anticancer agents. However, its clinical application is often limited by severe toxic side...

The preparation of Red Blood Cell (RBC) Ghosts is a well-known protocol in biological and medical research. It describes the extraction of the membranes from RBCs. Another well-known protocol is the preparation of highly ordered stacks of artificial lipid bilayers on silicon wafers. This technique is useful for analyzing the molecular structure and dynamical properties of these bilayers via...
