Photoacoustic tomography (PAT) is a hybrid imaging modality that combines rich contrast of
optical excitation and deep penetration of ultrasound detection. With its unique optical …

Photoacoustic imaging (PAI) is a rapidly growing field which offers high spatial resolution
and high contrast for deep‐tissue imaging in vivo. PAI is nonionizing and noninvasive and …

Controlling the internal structures of single‐chain nanoparticles (SCNPs) is an important
factor for their targeted chemical design and synthesis, especially in view of nanosized …

The pH dependence of the absorption and (time-resolved) fluorescence of two red-shifted
fluorescent proteins, mCardinal and mNeptune, was investigated. Decay-associated spectra …

In fluorophores, the excited state lifetime can be modulated using pump-probe excitation. By
generating photoacoustic (PA) signals using simultaneous and time-delayed pump and …

Pump-probe-based photoacoustic tomography (PP-PAT) is an innovative and promising
molecular imaging technique. In this study, we utilized PP-PAT for the first time, to the best of …

The heat action spectrum of Rhodamine B by two-photon absorption has been measured by
a new system of optical-probing photoacoustic spectroscopy (OPPAS) coupled with a …

Photoacoustic (PA) imaging is an emerging imaging technology with potential for preclinical
biomedical research and clinical applications. PA imaging, which relies on the generation of …

Significance: The large background, narrow dynamic range, and detector saturation have
been the common limiting factors in stimulated emission (SE)-based pump-probe …

In this Letter, we theoretically describe photoacoustic signal generation of molecules, for
which triplet relaxation can be neglected, by considering the excited state lifetime, the …
