Up until now, there have been few fluorophores developed for the 900-1,000 nm NIR-Ib window. This is largely because NIR-Ib light is thought to be strongly absorbed by water. %K near-infrared fluorescence imaging %K heptamethine dyes %K leaf vein imaging %K lymphatic imaging %K image-guided cancer surgery %U http://www.thno.org/v08p4116.htm
