Lanthanide oxide nanoparticles are promising luminescent probes in bioanalysis, because of their unique spectral properties, photostability, and low-cost synthesis. We report for the first time the application of europium-doped gadolinium oxide (Eu:Gd2O3) nanoparticles to the optical imaging of antibody micropatterns. The nanoparticles were synthesized by(More)
Lasing from spherical microdroplets ejected into a liquid medium with a lower refractive index is observed in a microchannel. A microfabricated device that combines droplet production and excitation/detection has been utilized. Droplets of 50 microm diameter containing a fluorescent dye were first detected and then excited through multimode fibers after(More)
Delta9-tetrahydrocannabinol (THC) has been shown to protect against focal and global ischemia. Hypothermia is thought to be one mechanism for this protection. These observations are important since brain hyperthermia is known to increase ischemic damage while hypothermia is protective. To establish the effect of THC on brain and body core temperature, brain(More)
