Cell stimulation using quantum dots
View Patent ↗The present invention provides methods for stimulating cells using quantum dots. In addition, the present invention provides methods for treating a variety of clinical conditions using stimulation of quantum dots to induce cell stimulation and/or function.
1. A method for providing a subject with endogenous night vision, the method comprising:
providing a quantum dot to the subject not experiencing or displaying symptoms of visual impairment, wherein the subject comprises a retina and the retina comprises a retinal cell;
wherein the quantum dot emits a local field charge in response to exclusively infrared radiation emitted by an object and not in response to wavelengths of light within the visible spectrum of light;
providing a bio-targeted material to localize the quantum dot proximal to the retinal cell; and
exposing the retina to infrared radiation, wherein the local field charge emitted by the quantum dot results in an action potential;
wherein the action potential results in a visual response; and
wherein the visual response provides the subject with endogenous night vision, allowing the subject comprising the retina to visualize the object in an environment without visible illumination.
2. The method of claim 1 , wherein the quantum dot is coated with the bio-targeted material.
3. The method of claim 2 , wherein the bio-targeted material is biotin or streptavadin.
4. The method of claim 1 , wherein the quantum dot is not photoluminescent.
