Semiconductor quantum rods manifest the transition from 0D dots to 1D wires and show potential advantages over dots in optical gain applications. Rod-shaped semiconductor nanocrystals possess clearly different optical properties in comparison to their dot-shaped analogues. A novel synthetic procedure that gave rod shaped CdSe nanocrystals, via thermal decomposition of precursors upon injection in a hot mixture of surfactants is reported. Biomolecules, such as transferrin (Tf), folic acid (FA), or antibodies, can be linked to the surfaces of hydrophilic QRs by using carbodiimide chemistry, producing QR bioconjugates. These functionalized QRs can be used in imaging of cancer cells.
