Lipid composition plays an important part in the structural and metabolic functions of cell membranes. In particular the production of inflammatory mediators such as prostaglandins and leukotrienes is dependent on polyunsaturated fatty acid precursors. Neutrophil leucocytes participate in inflammatory processes by their phagocytic and killing activities(More)
Here we demonstrate the design, fabrication, and characterization of ultrafast, surface-plasmon enhanced Au nanorod optical field emitter arrays. We present a quantitative study of electron emission from Au nanorod arrays fabricated by high-resolution electron-beam lithography and excited by 35 fs pulses of 800 nm light. We present accurate models for both(More)
OBJECTIVE To evaluate the clinical feasibility and safety of a new technique for liver resection using a new saline-coupled bipolar sealing device (Aquamantys®) that has shown high performance in the animal setting. PATIENTS AND METHODS Twelve Child-Pugh A cirrhotic patients with hepatocellular carcinoma underwent partial hepatectomies using Aquamantys®.(More)
Combining the ability to localize electromagnetic fields at the nanoscale with a directional response, plasmonic antennas offer an effective strategy to shape the far-field pattern of coupled emitters. Here, we introduce a family of directional multiresonant antennas that allows for polarization-resolved spectral identification of fluorescent emission. The(More)
We report on a template-stripping method for the direct surface patterning of colloidal quantum-dot thin films to produce highly luminescent structures with feature sizes less than 100 nm. Through the careful design of high quality bull's-eye gratings we can produce strong directional beaming (10° divergence) with up to 6-fold out-coupling enhancement of(More)
