Bioassays: Small 16/2009

The cover picture illustrates the transport of quantum dot (QD) “sandwiches” along surface-bound microtubule filaments by kinesin biomolecular motors. “Nanoharvesters” are assembled through the co-localization of kinesin motors and antibodies on red-emitting QDs, and form a double-antibody sandwich with antibody-coated green QDs when the antigen is present. For more information, please read the Communication “In vitro Capture, Transport, and Detection of Protein Analytes Using Kinesin-Based Nanoharvesters” by G. D. Bachand et al., beginning on page 1835.
