Freezing of erythrocyte-derived nanoparticles can provide a method to extend their storage life and enable rapid deployment for clinical applications. We found that key physical properties of the particles remained unaffected after one freeze-thaw cycle.

We engineered optical nanoparticles derived from erythrocytes and functionalized with ligands to target specific receptors on capillary endothelial cells. These particles may provide a new therapeutic approach for laser treatment of port wine stains.

We have engineered nano-constructs composed of plant virus capsid proteins encapsulating indocyanine green complexed with albumin. Our results that demonstrate the effectiveness of these nano-constructs for fluorescence imaging of ovarian cancer cells in vitro.
