Modern imaging techniques

Quantum dots are small semiconductor nanoparticles with great fluorescence properties including broad excitation and narrow emission spectra, high quantum yields, high photostability, possibility to be synthesize in a wide variety of colors and suitability for functionalization they are new member of a family of fluorescent labels. Due to their unique optical and electrochemical properties they have proven to be very beneficial not only for biomolecule labeling for in vitro analysis but also for in vivo applications. This review article is focused on the current imaging methods. The usage of fluorescence methods in diagnosis is discussed. This paper concerns to the fluorescence imaging and possibilities of the usage of quantum dots in in vivo imaging.
