NIBIB-supported researchers have developed a smart nanoprobe designed to infiltrate prostate tumors and send back a signal using an optical imaging technique known as Raman spectroscopy. The new probe, evaluated in mice, has the potential to determine tumor aggressiveness and could also enable sequential monitoring of tumors during therapy to quickly determine if a treatment strategy is working.

An automated tool captures circulating tumor cells in children with central nervous system cancers. The tool could make it easier to identify tumors that don't respond to treatment.

Researchers are developing new MRI contrast agents that are activated in low oxygen environments enabling improved diagnosis and treatment of hypoxic tumors as well as other diseases.

NIBIB-funded researchers are developing an imaging method that would allow surgeons to better identify cancerous cells in breast tumor margins during surgery. This technique could lead to a reduction in follow-up breast cancer surgeries and reduce rates of breast cancer recurrence.

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.

NIBIB-funded researchers are developing a method to activate natural killer cells using an external magnetic field, which not only enhances their cytotoxicity, but allows them to be tracked using magnetic resonance imaging (MRI) to verify that they’ve reached their target.

A team led by NIBIB scientists has developed hardware and software innovations to construct super-resolution, 3D confocal images of fine structures in living samples.

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.

NIBIB-funded researchers are investigating long-lasting, customizable nanobubbles for ultrasound contrast agents.

A novel method produces a new class of radioactive tracers that are used for medical imaging. The method allows them to attach radioactive atoms to compounds that have previously been difficult or even impossible to label.  The advance will make it easier to track medications in the body and identify tumors and other diseases.
