Chameleon clothes?

Scientists have observed the capabilities of fish to change their coloring. One group, led by George Bachand, has developed a simpler method. The method entails a change in color is due to the compactness or dispersion of quantum dots on microtubules which are cylindrical protein filaments. When these microtubules collide, they can twist together which forms small stable rings. These rings in turn can dissemble and thus cause either tightly packed or dispersed quantum dots. These dots of cadmium selenide reflect different light frequencies. This mimicking of color change in fish has large future real-world applications.
