title: Nanoscale controlled self-assembled monolayers and quantum dots.
abstract: Self-assembled monolayer (SAM) and fluorescent quantum dots (QDs) share common ground as emerging tools for nanoscale observation of biological interactions. SAMs provide excellent means of controlling the surface characteristics through individually tailored and engineered building blocks. SAMs on various surfaces have demonstrated clear advantages over uncontrolled multilayer films in fabricating electrochemical sensor, optical sensor, chemical biosensor, and atomic force microscopy. Similarly, QDs have advantages over organic fluorophores in long-term and real-time optical imaging of biological specimens. QDs conjugated with various biomolecules have been successfully applied to bioimaging, biosensing and cell encoding.
