This invention relates generally to a method, system, indicator and coating for the non-destructive detection of a predetermined condition. The invention relates more specifically to a method, system, indicator and coating that uses quantum dots that fluoresce under illumination to indicate the presence of a predetermined condition, and in particular, a corrosion condition.

For example, military and commercial aircraft undergo routine pre-flight, post-flight and periodic corrosion inspections and corrective maintenance. Often very expensive and time consuming techniques, such as x-ray radiography, ultrasonic imaging, and electromagnetic eddy current inspection methods may be used to detect corrosion. For many applications, damage due to corrosion is often difficult to detect. This is especially problematic on surfaces that are difficult to access with detection equipment.
