Welcome to SuNMag
SuNMag research efforts are dedicated to the discovery of new properties in nanoscale materials and to the development of new fabrication schemes for devices based on such materials. Nanoscale Materials are new, non-bulk materials composed of units that have at least one dimension in the nanometer size regime and each unit can be isolated and studied individually or can be used as a building block for larger and more complex ensembles. Nanoparticles, nanorods, nanotubes, and nanowires are the most commonly known nanoscale materials. They are mostly composed of an inorganic core and an organic ligand shell, thus they are very complex supramolecular assemblies. In SuNMaG, we study the role of the ligand shell, i.e. we want to understand what properties can be affected or modulated by changing the chemical nature of molecular ligands. We are presently using the molecular ligands as tools to modulate the (1) biological, (2) electronic, and (3) optical properties of metal nanoparticles and carbon nanotubes. We also use the molecular ligands as anchors to direct the self-assembly of these particles on lithographically-defined positions on a substrate.
The long term goal is to better understand the interfacial relationships between organic molecules and inorganic surfaces. We are in the MIT Department of Materials Science and Engineering. Our offices and labs are in Building 13 (Bush Building). For location of our offices and labs, please see the MIT campus map.
