Abstract
A method of controllably changing an intrinsic property of a quantum dot by using a biological entity, either attached or in close proximity to the quantum dot, and changing the state of biological entity with a controllable mechanism. The change in state of the biological entity controllably changes the intrinsic property of the quantum dot. The photoluminescence emission of quantum dots can be controlled by the present method. The methods disclosed include controlling the magnitude of QD photoluminescence as well as turning the photoluminescence on/off. The methods disclosed include using the same biological control architecture to control other intrinsic QD properties such as charge state, magnetic or other property.
