X-ray CT imaging can be complementary to fluorescence and photoacoustic imaging (FLI and PAI), allowing for high spatial resolution and high-sensitivity multimodal imaging for imaging guided treatment. In this study, the CT contrast agent iohexol was co-encapsulated with indocyanine green (ICG) within nanoliposomes (NLs) to explore their interaction and possible application of this liposomal formulation (LGI) in cancer theranostics. The photophysical properties of LGI were studied to assess the effect of iohexol on ICG that can enhance the efficiency of ICG-based near infrared photodynamic therapy (PDT). The CT, FLI and PA imaging abilities of LGI were also investigated. Furthermore, the near infrared phototherapy of cancer cells in vitro was performed, exhibiting higher phototherapy efficacy of LGI in comparison with other ICG formulations. We conclude that LGI can serve as a highly efficient theranostic nanoplatform for multimodal (fluorescence, CT and PA) imaging and near infrared phototherapy.

In this study, we successfully developed a diselenide-based, triple-responsive intelligent nanogel, IR780@BEAP, for lung cancer therapy. Exploiting the elevated levels of reactive oxygen species (ROS) and glutathione (GSH) in the tumor microenvironment (TME), a ROS/GSH dual-responsive diselenide cross-linker (DSe5) was synthesized and used to cross-link betulin (BE) with polysaccharide (AP) while coloading the photosensitizer IR780. The resulting nanogel, IR780@BEAP, exhibited an appropriate particle size (137.

Multimodal phototheranostics has been recognized as one of the most momentous advances in cancer treatment. Of particular interest is a single molecular species simultaneously featuring in multiple imaging and synergistic phototherapies; the development of such a molecular species is nevertheless a formidably challenging task. Herein, we innovatively designed and synthesized three aggregation-induced emission (AIE)-active molecules with emission in the second near-infrared (NIR-II) window, by employing 10-indeno[1,2-][1,2,5]thiadiazolo[3,4-]quinoxalin-10-one as the electron acceptor, 4-(-butyl)--(4-(-butyl)phenyl)--phenylaniline as the electron donor, and different π-bridge moieties.

In this research, biocompatible α-FeO nanoparticles were prepared as an agent for photothermal and photodynamic therapy methods by combining green synthesis and hydrothermal methods. The addition of chitosan bio-polymer played a crucial role in this process, as it not only stabilized the suspension of nanoparticles but also enhanced their biocompatibility. This stability was confirmed by zeta potential analysis Various analyses such as transmission electron microscope, X-ray diffraction, UV-visible spectrum, and Fourier transform infrared spectrum were performed to determine the structural and optical characteristics of the nanocomposite.

Near-infrared photoimmunotherapy (NIR-PIT) is a highly selective cancer therapy based on a targeted monoclonal antibody conjugated to phthalocyanine-based photoabsorber, IRDye700DX (IR700). Following injection, near-infrared light activates the conjugate causing direct cytotoxicity and immunogenic cell death. The high selectivity of NIR-PIT is traditionally based on the binding of a monoclonal antibody to its target thus bringing the photoabsorber, IR700, in close proximity to the cell membrane at the time of light exposure.
