Acc Chem Res August 2009

The current issue is on the chemistry of imaging and there's tons of stuff we should look at, esp. the CPP people:

Two-Photon Probes for Intracellular Free Metal Ions, Acidic Vesicles, And Lipid Rafts in Live Tissues

Lipid-Shelled Vehicles: Engineering for Ultrasound Molecular Imaging and Drug Delivery

Bioresponsive, Cell-Penetrating, and Multimeric MR Contrast Agents

Cell-Penetrating Metal Complex Optical Probes: Targeted and Responsive Systems Based on Lanthanide Luminescence
