Researchers funded by the National Institute Biomedical Imaging and Bioengineering (NIBIB), a part of the National Institutes of Health (NIH), have developed florescent nanoparticles that light up to track the progress of breast cancer metastasis. They are currently testing the particles in mice with the hope of someday being able to use them in humans.

“Seeing is believing,” has been taken to heart by researchers as they strive to develop microscopes that will reveal biological structures and processes with increased clarity and detail. Now, researchers funded by the National Institute of Biomedical Imaging and Bioengineering have developed a technique that uses the vibration of chemical bonds to produce specific colors that allow them to simultaneously observe, in cells and tissues, as many as 24 interacting molecules--each with a distinct color.

Fluorescent quantum dots are valuable tools used to tag and image biological processes in live animals. However, precise fluorescent imaging at the cellular and molecular levels has not been possible because of non-specific fluorescence and light scattering by surrounding tissues. Now researchers have resolved many of these problems by using SWIR quantum dots in live mice to image working organs, take metabolic measurements, and track microvascular blood flow in normal brain and brain tumors.

Researchers funded by the National Institute of Biomedical Imaging and Bioengineering (NIBIB) have developed a new tool for detecting early pancreatic cancer. The tool uses light-scattering spectroscopy (LSS), bouncing light off targeted tissue to detect structural changes in tissue. The researchers performed a series of pilot studies using LSS and accurately distinguished benign cysts, cancerous cysts, and those with malignancy potential 95 percent of the time. The Harvard University team reported their results in the March 13, 2017, issue of Nature Biomedical Engineering.

Brain surgery for removing cancerous tissue is a delicate and high-stakes task. Now researchers funded by NIBIB have created a way to improve tumor removal surgery by distinguishing cancerous tissue from healthy tissue faster. The method developed by researchers at the University of Michigan Medical School makes brain tumor surgery more precise, improving safety.
