(Invited) Carbon Nanotube-Hybrid Nanoscale Devices

Abstract

The controlled organization of individual molecules and nanostructures with nanoscale accuracy is key for the fabrication of the next generation optoelectronic devices and the investigation of events in biological and chemical assays. In this regard, we developed different platforms based on the in-solution assembly of classes of molecular materials (organic, inorganic, and biological with promising attributes) to single-walled carbon nanotubes (SWCNTs), employed as building blocks that allow for nanoscale studies to be performed in a variety of research fields.Through this approach, we assembled and investigated: molecular transport junctions,[1] metal nanowire devices using CNTs as vector templates,[2] static and dynamic organic-inorganic heterostructures consisting of Quantum Dot-CNT hybrids,[3,4] stimuli-responsive CNT-CdS/CNT-PbS devices[5] and DNA-CNT junctions,[6] protein-CNT nanohybrids,[7] and multiplexed biosensing devices based on aptamer- and protein-CNT heterostructures.[8,9] In this presentation, we will discuss relevant and recent examples among the aforementioned studies.[1] Journal of the American Chemical Society, 2016, 138, 2905-2908[2] Angewandte Chemie International Edition, 2019, DOI: 10.1002/anie.201902857[3] Small, 2017, 13, 1603042[4] Advanced Science, 2018, 5, 1800596[5] Submitted [6] Chemistry of Materials, 2019, 31, 1537-1542[7] Journal of the American Chemical Society, 2017, 139, 17834-17840[8] Nano Letters, 2018, 18, 4130-4135[9] Submitted
