A new direct method has been developed to determine protein-drug binding based on hollow fiber membrane solvent microextraction. Hollow-fiber membrane solvent microextraction coupled with high-performance chromatography with UV detection was employed to evaluate the binding characteristics of drugs to bovine serum albumin (BSA) and blood serum. It was found that the BSA and matrix in the blood ...

We demonstrate a high sensitivity all­fiber Mach–Zehnder interferometer (MZI) based on radial­aligned liquid crystal (LC) in a hollow optical fiber (HOF). The transmission spectrum of the liquid crystal­filled fiber MZI (LCF­MZI) was measured at different temperatures, and the thermal­induced wavelength shift of the interference spectrum probed. The experimental results indicate that the LC ali...

A multichannel mixed-conducting hollow fiber (MMCHF) membrane, 0.5 wt % Nb2O5-doped SrCo0.8 Fe0.2O3-d (SCFNb), has been successfully prepared by phase inversion and sintering technique. The crystalline structure, morphology, sintering behavior, breaking load, and oxygen permeability of the MMCHF membrane were studied systematically. The MMCHF membrane with porous-dense asymmetrical microstructu...

To understand the effect of fundamental thermal noise in hollow-core optical fibers, authors propose an adapted model and compare it to careful measurements. They find that use evacuated hollow cores could allow for order-of-magnitude improvement phase sensitivity with respect standard fiber, enabling better precision interferometric applications such as fiber gyroscopes laser frequency stabili...

There has been very little work done in the past to extend the wavelength range of fiber image bundles to the IR range. This is due, in part, to the lack of IR transmissive fibers with optical and mechanical properties analogous to the oxide glass fibers currently employed in the visible fiber bundles. Our research is aimed at developing high-resolution hollow-core coherent IR fiber bundles for...

In this review paper some recent advances on optical fiber sensors are reported. In particular, fiber Bragg grating (FBG), long period gratings (LPGs), evanescent field and hollow core optical fiber sensors are mentioned. Examples of recent optical fiber sensors for the measurement of strain, temperature, displacement, air flow, pressure, liquid-level, magnetic field, and the determination of m...
