Another significant contribution is the label-free plasmonic immunosensor designed for cortisol detection using a D-shaped optical fiber. This sensor achieved a detection range of 0.01 to 100 ng ...

"Unlike standard optical fibers, which are cylindrical, the tapered fibers we developed have a conical shape, which allows ... which means that light can enter the fiber and be delivered to ...

The light-coupled platform of optical fiber tips enables interaction ... solution in toluene is drop-casted onto the fiber tip, forming a dome-shaped layer about 100 μm thick.
