Kidney disease is known as a silent killer. That’s because the markers physicians look for to diagnose the disease, such as urea and creatinine levels in the blood, often appear normal even when up to 75% of kidney function has been lost. One inexpensive, noninvasive method for imaging kidneys is to use near-infrared fluorescence imaging to follow an organic dye as it travels through the organs. But such dyes have problems: They often don’t provide . . .
