A new type of optical fiber – a channel capable of transporting light – developed by MIT and Harvard Medical School researchers could make it far easier to detect the onset of disease early, or track the progress of healing and treatment. The new “stretchy,” rubber-like optical fiber created by the team can be stretched and bent, and is made almost entirely of water in the form of hydrogel, meaning it can better withstand conditions in the human body without damaging its surroundings. Researchers already use fiber optics to activate cells in the body, and often to trigger neurons located in the brain, but the existing materials’ uses are inflexible and potentially dangerous to patients. The new material is both tough and flexible, allowing it to work in biomatter like the brain without also posing a risk to surrounding biological material.
