3 part focus on present chemistry: web.mit.edu/chemistry/deutch/research.htmlthis second focus intrigues me: Particles/motion inside cells? "The second area of interest involves two-dimensional chemistry. This work includes study of the chemistry that takes place in constrained environments such as at fluid interfaces, inside cells, and in liquid crystal solvents, where the environment influences both the equilibrium distribution of particles and their dynamic motion. Most recently, a theory has been developed to predict the equilibrium shape of lipid bilayers (both on surfaces and in three dimensional vesciles) based on the competition between surface tension and dipolar forces." and other focuses on Chemistry now: The future of Nuclear Power: web.mit.edu/nuclearpower/skytroll

Appreciable global effort is underway to develop new routes to three-dimensional (3-D) nanostructured devices. To enable widespread commercialization, such processes must be capable of: i) precise 3-D fabrication on a fine scale and ii) mass production on a large scale. These often-conflicting requirements can be addressed with a revolutionary new paradigm that merges biological self-assembly with synthetic chemistry: Bioclastic and Shape-preserving Inorganic Conversion (BaSIC). Nature provides spectacular examples of micro-organisms (diatoms, coccolithophorids, etc.) that assemble intricate bioclastic 3-D structures. For example, tens of thousands of diatom species currently exist, with each species assembling silica nanoparticles into a microshell with a distinct 3-D shape and pattern of fine features. Through sustained biological reproduction, diatoms can generate enormous numbers of 3-D micro/nanostructures with identical morphologies. Such massive parallelism and species-specific (genetically-controlled) precision are highly attractive for device manufacturing. However, natural bioclastic chemistries are rather limited. With BaSIC, synthetic approaches have been developed to convert biogenic assemblies into non-natural chemistries (e.g., TiO2, ZrO2, MgO, BaTiO3, polymers, etc.), while preserving the 3-D shapes and fine (nanoscale) features. Future research on the genetic engineering of biomineralizing micro-organisms may be coupled with BaSIC to yield low-cost nanostructured devices with tailored shapes and tailored chemistries.
