The Theory Prize was given for research into diamond nanoparticles; the Experimental Prize was given for development of scanning tunneling microscope (STM) technology.
Positioning two or more molecules along a long DNA strand can cause the DNA molecule to adopt different shapes if the molecules interact. Quickly and cheaply separating these shapes by a simple gel electrophoresis assay provides a wealth of information about how the molecules interact.
Design and computational simulation of amyloid proteins of diverse functions from diverse sources enable the self-assembly of proteins that could provide scaffolds for diverse applications.
RNA origami brings new dimensions to nucleic acid nanotechnology by exploiting the much greater variety of RNA structural motifs (compared to DNA) to do what cannot easily be done with DNA origami, like fold into predetermined nanostructures rapidly while being transcribed.
Iterative coupling, purification, and cyclization of a large collection of organic building blocks promises a vast array of complex small and medium sized molecules as candidates for drug discovery, catalysis, and nanotechnology.
