Abstract
A fluorescent probe having a capsule of nanometric size and an aggregate of fluorogenic molecules coupled to the capsule is provided. The aggregate emits a fluorescent signal at one or more wavelengths within the fluorescence spectral range when the probe is illuminated by an excitation light beam at one or more wavelengths within the excitation spectral range. Preferably, the fluorescent spectral range is in the near-infrared region of the spectrum. In some embodiments, the capsule is a boron nitride (BN) nanotube and the aggregate comprise 3,6-Bis[2,2′]bithiophenyl-5-yl-2,5-di-n-octylpyrrolo[3,4-c]pyrrole-1,4-dione as fluorogenic molecules. In some embodiments, the 3,6-Bis[2,2′]bithiophenyl-5-yl-2,5-di-n-octylpyrrolo[3,4-c]pyrrole-1,4-dione fluorogenic molecules are in a J-aggregation state.
