Photoacoustic imaging has experienced exponential growth over the past decade, with
many applications in biomedicine. One application ideally suited to the analysis of single …

Over the last two and a half decades, photoacoustic (PA) imaging has become an important
area of research in biomedical optics. Combining the high contrast of optical imaging with …

We developed a label-free microfluidic acoustic flow cytometer (AFC) based on interleaved
detection of ultrasound backscatter and photoacoustic waves from individual cells and …

A label‐free method that can identify cells in a blood sample using high frequency
photoacoustic and ultrasound signals is demonstrated. When the wavelength of the …

We describe a new technique that combines ultrasound and microfluidics to rapidly size and
count cells in a high-throughput and label-free fashion. Using 3D hydrodynamic flow …

Current methods to evaluate the status of a cell are largely focused on fluorescent
identification of molecular biomarkers. The invasive nature of these methods–requiring …

Nondestructive, contactless, and label-free characterization of small particles plays an
important role in laboratory research and industrial manufacturing. Also, the analysis of …

A flow cytometer that uses sound waves to determine the size of biological cells is
presented. In this system, a microfluidic device made of polydimethylsiloxane (PDMS) was …

We have developed a flow cytometer based on simultaneous detection of ultrasound and
photoacoustic waves from individual particles/cells flowing in a microfluidic channel. Our …

A cell's nucleus-to-cytoplasm (N: C) ratio is a histological metric used to stage malignant
disease. Current N: C assessment methods, such as optical microscopy, are time …
