It is highly important and challenging to develop donor-acceptor-donor structured small-
molecule second near-infrared window (NIR-II) dyes with excellent properties such as water …

As the major pipeline for transporting oxygen and nutrients to living tissues, well‐ordered
and functional vasculature is vital to maintain the function of organisms. The cerebrovascular …

Here, we describe a fluorination strategy for semiconducting polymers for the development
of highly bright second near‐infrared region (NIR‐II) probes. Tetrafluorination yielded a …

Photoacoustic imaging is an emerging biomedical imaging technique that combines optical
contrast and ultrasound resolution to create unprecedented light absorption contrast in deep …

Exogenous contrast‐agent‐assisted NIR‐II optical‐resolution photoacoustic microscopy
imaging (ORPAMI) holds promise to decipher wide‐field 3D biological structures with deep …

Fluorescence imaging in the second near-infrared (NIR-II) window has attracted
considerable interest in investigations of vascular structure and angiogenesis, providing …

Optical resolution photoacoustic microscopy (OR-PAM) is a non-invasive, label-free method
of in vivo imaging with microscopic resolution and high optical contrast. Based on intrinsic …

Poor oxygenation of solid tumours has been linked with resistance to chemo-and radio-
therapy and poor patient outcomes, hence non-invasive imaging of oxygen supply and …

Neuroimaging techniques can reveal complex brain functions associated with behaviors
and emotions. However, most existing neuroimaging methods suffer from balancing …

Photoacoustic (PA) technology has been used extensively on vessel imaging due to its
capability of identifying molecular specificities and achieving high optical-diffraction-limited …
