Metal agents have made incredible strides in preclinical research and clinical applications in
recent years, but their short emission/absorption wavelengths continue to be a barrier to …

Nanomaterials have been extensively used for cancer therapy and diagnosis due to their
designability, multifunctionality, and unique in vivo distribution. Metal ions are increasingly …

Confusion is a novel concept of isomerism in porphyrin chemistry, delivering a steady
stream of new chemistry since the discovery of N-confused porphyrin, a porphyrin mutant, in …

NIR-II (1000–1700 nm) fluorescence imaging is continually attracting strong research
interest. However, current NIR-II imaging materials are limited to small molecules with fast …

Nanoarchitectonics is a concept envisioned to produce functional materials from nanoscale
units through fusion of nanotechnology with other scientific disciplines. For component …

Fluorescence and photoacoustic (PA) imaging in the second near-infrared (NIR-II, 1000–
1700 nm) window has garnered massive interest owing to high maximum permissible …

Phototheranostics constitute an emerging cancer treatment wherein the core diagnostic and
therapeutic functions are integrated into a single photosensitizer (PS). Achieving the full …

Photoacoustic imaging (PAI) relies on the use of contrast agents with high molar absorptivity
in the NIR-I/NIR-II region. Expanded porphyrins, synthetic analogues of natural tetrapyrrolic …

Photoacoustic imaging (PAI), which integrates the higher spatial resolution of optical
imaging and the deeper penetration depth of ultrasound imaging, has attracted great …

The NIR absorptivity of the metallotexaphyrin derivatives MMn, MGd, and MLu for
photoacoustic (PA)-based imaging is explored in this study. All three complexes …
