Specialized optical fibers are pivotal in advancing medical technologies, particularly enhancing minimally invasive procedures, laser treatments, biosensing, and diagnostics. These fibers enable visualization of internal organs with minimal incisions by delivering and transmitting light, thus facilitating quicker patient recovery. Their capability to convey high-powered laser light precisely targets areas for tumor removal, internal bleeding cessation, or delicate eye surgeries, minimizing surrounding tissue damage. Furthermore, these fibers can be engineered as sensors to detect physiological parameters such as temperature, pressure, and blood oxygen levels, offering advantages like minimal invasiveness and immunity to electromagnetic interference. In diagnostics, they enable techniques like remote fluorescence spectroscopy for early disease detection.
