Scientists of LEM, LP2N (France), Polytechnique Montréal, Université de Montréal (Canada) have succeeded in encapsulating organic dye molecules inside a boron nitride nanotube. This encapsulation protects efficiently organic dye molecules against degradations inherent to their surrounding conditions and improves the fluorescence over a time scale longer by 104 with respect to that of free dyes.
