The need for sensors in medical diagnostics has led to growing interest in the field of optical biosensors. These devices utilize optical techniques to detect and identify chemical or biological species. The interest in optical biosensors is motivated by several advantages, such as low cost, high sensitivity, high specificity, and the possibility of remote sensing and in vivo measurements. Optical biosensors can utilize a modification in the amplitude, phase, or frequency of an input beam in the detection mechanism. Nanosensors were fabricated with optical fibers pulled down to tips with distal ends in nanoscale dimensions.
Stretchable nano-devices towards smart contact lenses
Nanosensors with immobilized bioreceptor probes e. Laser light is launched into the fiber, and the resulting evanescent field at the tip of the fiber is used to excite target molecules bound to the antibody molecules.
A photometric detection system is used to detect the optical signal e. Antibody Data Search Beta.
