TAIPEI, Taiwan.—Apollo Medical Optics Inc. (Taipei, Taiwan) aims to revolutionize skin cancer detection without the need for invasive biopsies by using a single-crystal sapphire and yttrium aluminum garnet crystalline fibers—surrounded by glass and a flexible polymer cladding—to look through the skin and image suspicious skin anomalies non-invasively, instead of taking a skin sample and risk releasing malignant cancer cells into the bloodstream.
