The logo is based on an illustration I did for my Nanoscale Science, Engineering, and Technology course term paper. The illustration is based on a wonderful review paper by Katz and Willner on the integration of biomaterials with nanoparticles. A link to the paper follows.
Integrated Nanoparticle-Biomolecule Hybrid Systems: Synthesis, Properties, and Applications
The figure below shows a magnetic nanoparticle that has been coated with either gold or a mesoporous material to keep the iron stable in air. Linker molecules are then used to attach various biomolecules to the nanoparticle to give it functionality. The figure shows a summary of the different functions that could be attached to the magnetic nanoparticle. In practice, only one biomolecule would be attach along with a photoluminescent marker and injected in to a mouse with cancer to see how effective the biomolecule is at targeting a specific type of cancer. The magnetic nanoparticle (mnp) shows up as a contrast enhancement agent in an MRI and the photoluminescent marker can be used in a microscope for tissue studies.
Katz and Willenr wrote the book Bioelectronics: From Theory to Applications
that looks very interesting but is still a bit pricey for me.
