The present invention relates to ligands, nanocrystal complexed with the ligands and their use for bio-imaging.

Enhanced affinity ligands

A device that emits light in response to an electrical or optical excitation, such as LEDs, displays, e-readers, device includes at least one anisotropic flat colloidal semiconductor nanocrystal whose smallest dimension, namely the thickness, is smaller than the other two by a factor of at least 1.5, the emitted light having an intensity and a polarization that vary according to the angle formed by the light emitting direction and the normal to the largest surface of the flat nanocrystal. The device allows to realize a light-emitting device exhibiting simultaneously a high emission spectral finesse and allows proper control of the wavelength, the directivity and/or polarization of the emitted light, and thus increases the brightness and color gamut of displays composed of such a device. Such devices are found for example in displays, televisions, mobile phones, tablets, or computers. The various embodiments of these devices are also presented.

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.
