Hypoxia, a salient feature of most solid tumors, confers invasiveness and resistance to the
tumor cells. Oxygen-consumption photodynamic therapy (PDT) suffers from the undesirable …

The living system is critically depended on the inner microenvironment and redox small
biomolecules to maintain the normal physiological processes. Consequently, tracing and …

We present the synthesis, photophysical properties, and biological application of nontoxic 3-
azo-conjugated BODIPY dyes as masked fluorescent biosensors of hypoxia-like conditions …

Hypoxia is a common feature of the tumor microenvironment, which is characterized by
tissue oxygen deficiency due to an aggressive proliferation of cancer cells. Hypoxia …

Azo compounds are widely distributed synthetic chemicals in the modern world. Their most
important applications are as dyes, but, in addition, several azo compounds are used as …

Tumor blood vessel formation is a key process for tumor expansion. Tumor vessels are
abnormal and differ from normal vessels in architecture and components. Besides oxygen …

Azo molecules possess the characteristic azo bond (-N= N-) and are considered fascinating
motifs in organic chemistry. Since the last century, these brightly colored compounds have …

Abstract Zinc oxide nanoparticles (ZnO NPs) are important semiconductor materials with
interesting photo-responsive properties. During the past, ZnO-based NPs have received …

Photoacoustic imaging using energy conversion from light to ultrasound waves has been
developed as a powerful tool to investigate in vivo phenomena due to their complex …

Hypoxia is a ubiquitous feature of solid tumors, which plays a key role in tumor angiogenesis
and resistance development. Conventional hypoxia detection methods lack continuous …
