A method for using a photon source, which includes a semiconductor structure having a first light emitting diode region, a second region including a quantum dot, a first voltage source, and a second voltage source, is provided. The method includes steps of applying an electric field across said first light emitting diode region to cause light emission by spontaneous emission, wherein the light emitted from said first light emitting diode region is absorbed in said second region and produces carriers to populate said quantum dot; and applying a tuneable electric field across said second region to control the emission energy of said quantum dot, wherein the light emitted from the second region exits said photon source.

The present invention provides a method of assessing whether an individual is at high risk or low risk of inflammatory bowel disease (IBD) progression by determining the expression level of two or more genes in a whole blood sample. Also provided are methods for treating IBD in an individual who is determined to be at high risk or low risk for IBD progression, and kits for assessing whether an individual is at high risk or low risk for IBD progression. Arrays, and methods of providing arrays, of patient-identified selected gene expression products from a whole blood sample of a patient are also provided.
