Artificial objects and Natural products
> In the nature, molecules assemble by themselves and produce a minute nanostructure under a low
energy (low temperature, ordinary pressure).
> Microfabrication can create controlled microstructures.
> It is difficult to create natural structures under a nanoscale (missing area).
> We construct a structure controlled sizes from an angstrom to a meter scale, embedding the nano
scale structure produced by living things in artifacts.
Artificial cell membranes (Lipid Bilayer) and membrane proteins
> Phospholipid molecules spontaneously form bilayer lipid membranes by
Hydrophobic and Hydrophilic Interaction in the water.
> Membrane proteins perform various functions in the cell membranes.
> Some membrane protein transport substances, energy and information between
outside and inside the cells.
> Membrane proteins perform as the transporter of ions and medicines, the receptor
of odorant and light, and the perception of mechanical stress
MEMS(MicroElectroMechanicalSystem) and membrane proteins
In our laboratory,
> We manufacture the platform for preparing artificial cell membranes by using a micro
electro mechanical system (MEMS).
> System construction for measuring the signals of membrane protein reconstituted in
lipid bilayer membranes.
> Application for biosensor, drug development and physicochemical study in controlled
> Utilizing molecules, proteins, DNA/RNA, lipid, cell, MEMS, microfluidics techniques in
Micro-sized processing techniques (Lithography, Milling)
> Microfabrication by photolithography in a clean room.
> CAD/CAM micromilling for plastic fabrication.
> Manufacture of electrodes by metal deposition and confirmation of processing accuracy
by a measuring microscope.
Droplet contact method: Formation of artificial cell membranes
> Applying of oil/lipid solution and buffer solution into a chamber, two lipid monolayers
are formed at the surface of aqueous droplets.
> Two droplet contact together and bilayer lipid membrane can be formed.
> Artificial cell membranes mimicking natural cell membranes are able to be formed by
various types of lipid molecules.
A electrical single molecule detection by nanopore sensing
> Ions pass through a nanopore (≈1.4 nm in diameter) reconstituted in membranes
cause current increase.
> A translocating molecules through the pore show the blocking current.
> Application: drug testing, food inspection, and diagnostic pathology.
The mimetic device of cellular information transfer mechanism
> Bottom-up construction with biological molecules for “Molecular robot”.
> Construction of logic circuits modeled after living cells by networking droplets.
> Large-scale parallel computation of the droplet system by combining chemical sensing
Electrical molecular computing using nanopores
> DNA computing, which uses programmed DNA as logic elements, enables large-scale
parallel computation which is difficult for existing computers.
> Although this calculation requires longer detection time because of DNA amplification
by PCR and detection by fluorescence imaging, we implemented a reduction of detection
time by electrical detection using nanopore sensing.
> Nanopores enable the detection and translocation to next droplet at the single molecule
Reconstitution membrane proteins in lipid bilayers
> Antimicrobial peptides kill mycetocyte by forming nanopore into the cell membranes.
> Pore-forming of the antimicrobial peptide is measured electrically using artificial cell
> Clarification of pore-forming mechanism of the antimicrobial peptide and its application
of antimicrobial drugs are expected.

> Microfluidic enables energy and sample saving in chemical analysis by microscale
operation or chemical reaction on a microchip.
> The flow velocity in micro channels can be controlled precisely.
> The simultaneous chemical reaction is caused by flowing into some reaction fields
> The control of a flux in an oil layer and a water layer enables to form the uniform-
