Lieber Research

The Lieber group is focused broadly on science and technology at the nanoscale within a common intellectual vision: the bottom-up paradigm for nanoscale science and technology. This paradigm rests on the design and synthesis of nanoscale components --  building blocks -- that can be tailored down to the atomic scale and subsequently elaborated as single structures or assemblies to yield virtually any kind of functional structure or nanosystem. We are currently pursuing this paradigm in areas ranging from nanoprocessors through novel nanoelectronic-based biological tools and cyborg tissues.
