“…2d). 49 An in vitro experiment showed that an imaging depth up to 4.6 cm, and an in vivo experiment verified the clinical feasibility of Bi 2 Se 3 nanoagents by PAI of the bladder, gastrointestinal tract, and sentinel lymph nodes in mice. Copper sulphide (CuS)-based nanoparticles are promising nanoagents due to their negligible toxicity, excellent NIR-II absorption, and efficient biodegradability.…”

“…Using near-infrared (NIR) light can extend the maximum imaging depth because biological tissues pose relatively less optical attenuation in this wavelength range [56]. Particularly, the second NIR window (NIR II; ˜1000 nm – 1350 nm) gains great attention because hemoglobin absorption is much lower and tissue scattering is much less compared to those in the first NIR window (NIR I; ˜700 nm – 950 nm) [57]. Further, according to the American National Standards Institute (ANSI), the maximum permissible energy for skin allowed in the NIR-II window is higher than the VIS and NIR-I optical ranges [58,59].…”

Photoacoustic imaging (PAI) has many interesting advantages, such as deep imaging depth, high image resolution, and high contrast to intrinsic and extrinsic chromophores, enabling morphological, functional, and molecular imaging of living subjects. Photoacoustic microscopy (PAM) is one form of the PAI inheriting its characteristics and is useful in both preclinical and clinical research. Over the years, PAM systems have been evolved in several forms and each form has its relative advantages and disadvantages. Thus, to maximize the benefits of PAM for a specific application, it is important to configure the PAM system optimally by targeting a specific application. In this review, we provide practical methods for implementing a PAM system to improve the resolution, signal-to-noise ratio (SNR), and imaging speed. In addition, we review the preclinical and the clinical applications of PAM and discuss the current challenges and the scope for future developments.

“…[110][111][112][113][114][115] The PA signal generated by NIR-II wavelengths is weak and hence effective contrast agents are often necessary for enhancing the image contrast. With the increasing demonstrations on the advantages of PAI, efforts are made to develop strong NIR-II absorbing organic, 37,[116][117][118] inorganic, [119][120][121][122][123][124][125][126] etc. Although, these nanoparticles show broad absorption spectrum in the NIR-II window, most of them are demonstrated for PAI at 1064-nm wavelength because 1064-nm nanosecond laser (Nd:YAG laser) is commercially available.…”

Photoacoustic imaging in the second near-infrared window: a review

Photoacoustic (PA) imaging is an emerging medical imaging modality that combines optical excitation and ultrasound detection. Because ultrasound scatters much less than light in biological tissues, PA generates high-resolution images at centimeters depth. In recent years, wavelengths in the second near-infrared (NIR-II) window (1000 to 1700 nm) have been increasingly explored due to its potential for preclinical and clinical applications. In contrast to the conventional PA imaging in the visible (400 to 700 nm) and the first NIR-I (700 to 1000 nm) window, PA imaging in the NIR-II window offers numerous advantages, including high spatial resolution, deeper penetration depth, reduced optical absorption, and tissue scattering. Moreover, the second window allows a fivefold higher light excitation energy density compared to the visible window for enhancing the imaging depth significantly. We highlight the importance of the second window for PA imaging and discuss the various NIR-II PA imaging systems and contrast agents with strong absorption in the NIR-II spectral region. Numerous applications of NIR-II PA imaging, including whole-body animal imaging and human imaging, are also discussed.
