Photoacoustic (PA) imaging is an emerging imaging modality whereby pulsed laser
illumination generates pressure transients that are detectable using conventional ultrasound. …

Accumulation of reactive oxygen and nitrogen species (RONS) can induce cell damage and
even cell death. RONS are short-lived species, which makes direct, precise, and real-time …

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 or …

The transmission of SARS‐CoV‐2 coronavirus has led to the COVID‐19 pandemic. Nucleic
acid testing while specific has limitations for mass surveillance. One alternative is the main …

Chronic wounds are a major health problem that cause the medical infrastructure billions of
dollars every year. Chronic wounds are often difficult to heal and cause significant discomfort…

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

Photoacoustic (PA) imaging holds great promise as a noninvasive imaging modality. Gold
nanorods (GNRs) with absorption in the second near-infrared (NIR-II) window have emerged …

We report the peptide-programmed fractal assembly of silver nanoparticles (AgNPs) in a
diffusion-limited aggregation (DLA) mode, and this change in morphology generates a …

Chronic wounds and amputations are common in chronic kidney disease patients needing
hemodialysis (HD). HD is often complicated by drops in blood pressure (BP) called intra-…

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