Absorption of 808 nm laser light by liposomes containing a pH sensitive, near-infrared croconaine rotaxane dye increases dramatically in weak acid. A stealth liposome composition permits acid activated, photothermal heating and also acts as an effective nanoparticle probe for ratiometric photoacoustic imaging of acidic pH in deep sample locations, including a living mouse.

The invention discloses a pH reversible activation type photo-thermal/photodynamic/fluorescent integrated probe molecule, and belongs to the technical field of biological medicines. A pH-responsive asymmetric cyanine structure is used as a core unit, and through structural modification and introduction of halogen and other heavy atoms into a conjugated system, a photo-thermal/photodynamic/fluorescent integrated probe molecule capable of being specifically activated by a tumor weakly acidic microenvironment is constructed. The photo-thermal/photodynamic/fluorescent integrated probe has good stability, a good photo-thermal effect and excellent active oxygen generation capacity, and has huge potential in tumor treatment.

The development of sensitive and reliable fluorescent probes for the early diagnosis of Alzheimer's disease (AD) is highly challenging and plays an important role in achieving effective treatments. Herein, we designed and synthesized an indole-based fluorophore for TTR in human plasma, an important hallmark of AD pathogenesis. This robust and simple fluorescent method allows quantification of TTR in the complex biological matrix.
