Metal-enhanced e-type fluorescence
In this letter, we report metal-enhanced e-type fluorescence. Eosin in close proximity to silver island films (SiFs) shows enhanced e-type fluorescence with an approximately two-fold higher intensity ...

The direct integration of light and optical control into microfluidic systems presents a significant hurdle to the development of portable optical trapping-based devices. We present a simple, inexpensive fiber-based approach that allows for easy implementation of diode bars for optical particle separations within flowing microfluidic systems. We also develop models that demonstrate the advantages of manipulating particles within flow using linear geometries as opposed to individually focused point traps as traditionally employed in optical trapping micromanipulation. ©2008 American Institute of Physics
