Bioinspired Artificial Melanosomes As Colorimetric Indicators of Oxygen Exposure.

摘要: Many industries require irreversibly responsive materials for use as sensors or detectors of environmental exposure. We describe the synthesis and fabrication a nontoxic surface coating that reports oxygen exposure substrate material through irreversible formation colored spots. The consists selectively permeable rubber film contains colorless organic precursors to darkly pigmented synthetic melanin. Melanin within is triggered by molecular oxygen. regulates rate diffusion, enabling independent control sensitivity response time artificial melanosome, while preventing leaching melanin its precursors.
