Staining of microtumors with DIR-RGD-NP. Fluorescence spectral images from dissected intestines and the attached mesentery. Images shown are from mCherry channel (red; left column) and DIR channel (green; middle column). The merged images (right column) demonstrate the best colocalization of mCherry and DIR signals (white arrow) in animals that received DIR-RGD-NP. A representative animal for each delivery system is shown; (n&thinsp;=&thinsp;4 for soluble DIR and DIR-NP; n&thinsp;=&thinsp;12 for DIR-RGD-NP).

Enhanced retention and better colocalization <em>in vivo</em> with DIR-RGD-NP. Upon establishment of tumors (ROI~40,000), mice were given four doses of soluble DIR, DIR-NP, or DIR-RGD-NP given every other day. mCherry (red) and DIR (green) fluorescent images were obtained in live animals at designated time points 24&thinsp;h after the 4th dose. Images shown are merged images demonstrating the best colocalization of mCherry and DIR signals (yellow) in animals that received DIR-RGD-NP.

Staining and delineation of tumors and tumor-associated vasculature by DIR-RGD-NP. Upon establishment of tumors (ROI~40,000), mice were given four doses of DIR-RGD-NP given every other day (n&thinsp;=&thinsp;12). (A&ndash;D) Gross tumors appear distinctly stained compared to the intestines. Staining is specific to tumor-associated vasculature (white arrow), which can be easily contrasted to the normal vasculature (yellow arrow); (E,F) Tumors under the diaphragm are likewise stained; (F) Micrometastasis (blue arrow) is visible due to DIR-stained vessels (white arrow) and is contrasted against normal vessels (yellow arrow).

DiI, DiO, DiD and DiR dyes are a family of lipophilic fluorescent stains for labeling membranes and other hydrophobic structures. The fluorescence of these environment-sensitive dyes is greatly enhanced when incorporated into membranes or bound to lipophilic biomolecules such as proteins although they are weakly fluorescent in water. They have high extinction coefficients, polarity-dependent fluorescence and short excited-state lifetimes. Once applied to cells, these dyes diffuse laterally within the cellular plasma membranes, resulting in even staining of the entire cell at their optimal concentrations. The distinct fluorescence colors of DiI (orange fluorescence), DiO (green fluorescence), DiD (red fluorescence) and DiR (deep red fluorescent) provide a convenient tool for multicolor imaging and flow cytometric analysis of live cells. DiO and DiI can be used with standard FITC and TRITC filters respectively. Among them DiD is well excited by the 633 nm He-Ne laser, and has much longer excitation and emission wavelengths than those of DiI, providing a valuable alternative for labeling cells and tissues that have significant intrinsic fluorescence. DiR might be useful for in vivo imaging or tracing due to the effective transmission of infrared light through cells and tissues and low level of autofluorescence in the infrared range.
