Bright Nanoparticles Are Key to Better Medical Imaging
An international research team has created unique photoluminescent nanoparticles that shine clearly through more than 3 centimeters of biological tissue – a depth that makes them a promising tool for deep-tissue optical bioimaging.
Though optical imaging is a robust and inexpensive technique commonly used in biomedical applications, current technologies lack the ability to look deep into tissue, the researchers say. This creates a demand for the development of new approaches that provide high-resolution, high-contrast optical bioimaging that doctors and scientists could use to identify tumors or other anomalies deep beneath the skin.
