Abstract
A novel quantum dot capable of near infrared emissions at wavelengths of 750-1100 is made by forming solid solutions of metal sulfide, metal selenide or metal sulfide selenide by incorporating a suitable amount of an additional metallic element or elements to provide an emission wavelength in the range of 750 nm to 1100 nm. The quantum dots may be enabled for bioconjugation and may be used in a method for tissue imaging and analyte detection.
