Photoacoustic (PA) imaging is a non-ionizing imaging platform that combines light and ultrasound to safely image structures and molecules in the body. Researchers have now designed a nanoparticle-based PA contrast agent that targeted and significantly enhanced photoacoustic images of ovarian tumors in a mouse model.

Fluorescent “dots” – that is, tiny particles that can emit light – have a multitude of promising biomedical applications, yet making such dots is usually a long and tedious process that uses harsh chemicals. Now, NIBIB-funded researchers are developing a fluorescent dot that is not only easier to make, but uses environmentally friendly materials.

Scientists report they have designed and successfully tested an experimental, super small package able to deliver molecular signals that tag implanted human cancer cells in mice and make them visible for destruction by the animals' immune systems. The new method was developed, say the researchers, to deliver an immune system 'uncloaking' device directly to cancer cells.
