Photonic Crystal Fiber Based Refractive Index Sensor

Nazeri K., Ahsani V., Ahmed F., Lee P-C, Jun M.B.G., Purdue University, US

Photonic Crystal Fiber (PCF) is an optical fiber which owes its waveguide properties to an arbitrary arrangement of closely-spaced and tiny air holes that go through the whole length of fiber. Much attention has been [...]

An amperometric on-chip glucose biosensor based on enzyme entrapment with pre-reaction to lower interference in a flow injection system

Nien P.-C., Huang M.-C., Chang F.-Y., Ho K.C., National Taiwan University, TW

In this study, the flow injection analysis was applied to the enzyme-entrapped sensor on a chip for sensing glucose. The microelectrode arrays on a chip of 7×3.5 cm2 were fabricated by standard photolithographic and the [...]

Optical Surface Diffraction and Improved Lateral Resolution

Bacsa W.S., Caumont M., CNRS, UPS, BU, US

Optical coherence plays an important role in the local field in the vicinity of surfaces where the incident and scatter field overlap (1). While phase differences are small in the optical nearfield, the longitudinal component [...]
