 The
main research efforts of our group focus on the
fabrication of functional nanomaterials by assembling nanobuilding
blocks into designed patterns. The nanobuilding blocks
that we employ range from nanospheres of polymeric latexes or metal
oxides to amphiphilic molecules such as surfactants and block copolymers.
To create all best-performing materials requires the precise control
of their microstructures. During the last decade in our group, we
have developed a general framework for predicting the self-assembled
microstructures of nanobuilding blocks under equilibrium and nonequilibrium
conditions. A variety of the fabrication strategies for designed microstructures
have been undertaken utilizing soft microfluidic devices, electrohydrodynamic
atomization, capillary interactions, holographic lithography, multiphoton
absorption polymerization and DNAs (or proteins) as linker molecules.
The designed nanostructures create unusual fascinating multifunctions.
Recently, researches in our group are addressing three broad categories;
firstly, fabrication of photonic crystal (PC) chips, 2D array of microlenses
for PC-based microdisplay, and DNA-directed photonic crystals; secondly,
biomolecule-assisted defect-free nanocrystals and biofunctional assembly
of nanobarcodes for proteomics, genomics and drug discovery; thirdly
and finally, nanopatterning of mesopores or micropores for spintronic
memory devices and permselective membranes.
