Gili recently published a study in Nature Nanotechnology, “A wavelength-induced frequency filtering method for fluorescent nanosensors in vivo.”

Fluorescent sensors, which can be used to label and image a wide variety of molecules, offer a unique glimpse inside living cells. However, they typically can only be used in cells grown in a lab dish or in tissues close to the surface of the body, because their signal is lost when they are implanted too deeply.

MIT engineers have now come up with a way to overcome that limitation. Using a novel photonic technique they developed for exciting any fluorescent sensor, they were able to dramatically improve the fluorescent signal. With this approach, the researchers showed they could implant sensors as deep as 5.5 centimeters in tissue and still get a strong signal. An article was also published in  MIT News.
