![FIGURE 1: A tumor-induced integrin expression is imaged using a receptor-targeted NIR fluorescent molecular probe. Heterogeneity of tumor tissue is highlighted by hot regions (red color) in a magnified image of the tumor. These hot spots correlate with increase in mitochondrial NADH, suggesting highly metabolic regions of the tumor. Uptake in excretion organs (liver and kidneys) is evident [10].](https://img.laserfocusworld.com/files/base/ebm/lfw/image/2015/12/58107.png?auto=format,compress&fit=crop&q=45&h=139&height=139&w=250&width=250 "FIGURE 1: A tumor-induced integrin expression is imaged using a receptor-targeted NIR fluorescent molecular probe.
