Imaging the Distribution of High Colloidal Stability Mesoporous Silica Nanoparticles (MSNs) with PET and MRI

Laprise-Pelletier M., Bridot J.-L., Guillet-Nicolas R., Lagueux J., Gossuin Y., Laurent S., Vander Elst L., Kleitz F., Fortin M.-A., Université Laval, CA

Biocompatible and high porosity mesoporous silica nanoparticles (MSNs) represent a significant advance in drug delivery applications, currently entering clinical validation. It will be necessary to track these drug vectors over time with medical imaging techniques. [...]

Hybrid Nanoparticles Targeted by Antitumor Antibodies and Emitting Alpha-particles

Resheto I.V., Deev S.M., Chuvilin D.Y., Panchenko V.Y., Sukharev S.S., Streltsova E.A., P.A.Hertzen Moscow Research Oncological Institute (MROI), RU

We describe a new therapeutic nanoparticle’s design, which consists of three parts: targeting, effecter and linker. Targeting part: an anti-HER2/neu mini-antibody-barnase fusion protein (4D5 scFv-barnase-His5). The anti-HER2/neu mini-antibody could be used to deliver barnase to [...]

Imprint Lithography-Based, Multimodal Contrast Agents and the Effect of Shape and Size on Biodistribution

Herlihy K.P., Merkel T.J., DeSimone J.M., UNC Chapel Hill, US

Polymer research and modern medicine are at a critical juncture. Many state of the art, small molecule therapeutics are difficult to deliver effectively because of poor solubility and rapid elimination by the reticuloendothelial system. In [...]
