PURPOSE To evaluate the in vitro response of retinal pigment epithelial (RPE) cells to a nonlethal dose of blue light. METHODS The human RPE cell line ARPE-19 was irradiated with blue light (405 nm) at an output power of 1 mW/cm(2) or 0.3 mW/cm(2). The following parameters were studied: metabolic activity; apoptosis; reactive oxygen species (ROS) production; mitochondrial membrane potential (...

A cellulose biopolymer was doped with Fe and Al forming a mesoporous composite. The composite showed excellent adsorption capacities of 117.86 mg g −1 95.62 for Reactive red 21 blue 19 respectively.

Magnetic poly(p-phenylenediamine) (PpPD) nanocomposite was synthesized via mixing p-phenylenediamine solution and Fe3O4 nanoparticles and used as a carrier for immobilized enzymes. Successful synthesis of PpPD/Fe3O4 nanofiber was confirmed by transmission electron microscopy and Fourier transform infrared spectroscopy. Laccase (Lac) was immobilized on the surface of PpPD/Fe3O4 nanofiber through...
