Research Summary

HDnanomaterials are a new class of 3D bulk material elements that can be tailored at the sub nm-scale by combining solution-based layer-by-layer (LBL) processing and related techniques (Cohen-Rubner) with bulk nanoporous carbon scaffolds recently developed and demonstrated as microfluidic elements (Toner-Wardle). Toner-Wardle recently demonstrated microfluidic devices integrating ultra-high porosity (>99% porosity) nanoporous bulk elements for flow-field manipulation and filtering of nm- through micro-scale bioparticles. The nanoporous microfluidic elements provide a textured 3D set of nano-scale surfaces that are uniquely accessible to the LBL technique due to their ultrapermeable nature, going far beyond what is capable with nanoscale filtering concepts. Combining the two groups' contributions yields a unique-to-MIT platform for creating 3D bulk materials where self-terminating molecular layers are assembled on macroscopic (cm-scale) nanoporous scaffolds with the possibility of spatial tailoring in all 3 dimensions
