| One dimensional nanomaterials, such as nanowires (NWs), represent the smallest dimension for efficient transport of electrons and excitons and thus are promising building blocks to realize miniaturization of electronic devices. To achieve substantial potential of NWs in the area of nanotechnology will require the controlled assembly of well-ordered structures. Here we assemble CdTe NWs with bioconjugation technique. Cross-over and side to end are the two major preferential alignment fashion. Such CdTe NWs prepared in aqueous show abundant surface chemistry due to various available stabilizing reagents which offers advantage in surface modification with bio molecules. Conductivity studies show that the crossed nanowire arrays form non-conducting networks. The formation of conjugate complex results in Foster resonance energy transfer between NWs with different absorbance wavelength. |
