A nanosized extract of the plant thylakoid grana — the molecular engine behind photosynthesis — is transplanted into the eye's corneal cells, producing a key protective molecule when exposed to ambient light, opening a new front against dry eye disease
SINGAPORE, May 15, 2026 /PRNewswire/ -- What if your eyes could use light to heal themselves? Drawing inspiration from how plants harness sunlight, researchers at the National University of Singapore (NUS) are pioneering a revolutionary treatment for dry eye disease. Their approach uses a light-activated technology derived from the photosynthetic membranes of the spinach plant, enabling the eye to stay continuously hydrated. This offers a solution that is simple, effective and non-invasive.
