The etiology of peri-implant crestal bone loss is today better understood and certain factors
proposed in the past have turned out to not be of concern. Regardless, the incidence of …

The use of gold nanoparticles as diagnostic tools is burgeoning, especially in the cancer
community with a focus on theranostic applications to both cancer diagnosis and treatment …

Low fluence illumination sources can facilitate clinical transition of photoacoustic imaging
because they are rugged, portable, affordable, and safe. However, these sources also …

The major optical absorbers in tissue are melanin and oxy/deoxy-hemoglobin, but the
impact of skin tone and pigmentation on biomedical optics is still not completely understood …

Activatable contrast agents are of ongoing research interest because they offer low
background and high specificity to the imaging target. Engineered sensitivity to protease …

Cerebral hypoxia is a severe injury caused by oxygen deprivation to the brain. Hypoxia in

BACKGROUND More than a century ago, Alexander G. Bell first observed the photoacoustic
effect. He found that absorption of electromagnetic waveforms, such as radio frequency (rf) …

Light-emitting diode-based photoacoustic imaging is more compact and affordable than
laser-based systems, but it has low power and hence a high number of replicates. Here, we …
