Laser-induced instabilities in liquid crystal cells with a photosensitive substrate [PDF]
, 2014 Liquid crystal layers sandwiched between a reference plate and a photosensitive substrate were investigated. We focused on the reverse geometry, where the cell was illuminated by a laser beam from the reference side. In planar cells instabilities occurred, static and dynamic ones, depending on the angle between the laser polarization and the director ...

Analysis of Biomedical Signals by Flicker-Noise Spectroscopy: Identification of Photosensitive Epilepsy using Magnetoencephalograms [PDF]
Laser Physics (2009) 19(4): 836-854, 2008 The flicker-noise spectroscopy (FNS) approach is used to determine the dynamic characteristics of neuromagnetic responses by analyzing the magnetoencephalographic (MEG) signals recorded as the response of a group of control human subjects and a patient with photosensitive epilepsy (PSE) to equiluminant flickering stimuli of different color combinations.

H2O2‐Generating Advanced Nanomaterials for Cancer Treatment
Advanced Functional Materials, EarlyView.H2O2‐generating nanoplatforms can exploit tumor redox imbalance for O2 and toxic reactive oxygen species generation, leading to hypoxia reversal, and apoptosis of cancer cells, respectively. This review highlights the mechanisms of these nanoplatforms, including exogenous H₂O₂ delivery, endogenous amplification, and metal peroxides, which leads to ...

In vitro reduction of pathogenic sporothrix schenckii fungus by photodynamic therapy
O Mundo da Saúde, 2017 Sporotrichosis is a disease that affects the lymph vessels, skin and some internal organs. Most cases are presented as a subacute chronic mycosis caused by the Sporothrix schenckii fungus; fairly common in tropical regions. The aim of this study was to

Advanced Healthcare Materials, EarlyView.A magnetic microrobot fabricated by Spirulina platensis is proposed to accumulate in tumor regions and generate in situ high calcium concentration and sufficient oxygen. These characteristics of the microrobot present a strategy for triggering calcium overload therapy and chlorophyll‐mediated photodynamic therapy, and such combination resulted in a ...
