He is currently the Director of Supermolecules Group and Principal Investigator of World Premier International (WPI) Research Centre for Materials Nanoarchitectonics (MANA), the National Institute for Materials Science (NIMS). His research is oriented to supramolecular chemistry, surface science, and functional nanomaterials (Langmuir-Blodgett film, layer-by-layer assembly, self-organized materials, sensing and drug delivery, molecular recognition, mesoporous material, etc. and he is now trying to combine them into a unified field. AbstractDesigning nanoscale components and units into functional defined systems and materials has recently received attention as a nanoarchitectonics approach. In particular, exploration of nanoarchitectonics in two-dimensions (2D) has made great progress these days. Basically, 2D nanomaterials are a center of interest owing to the large surface areas suitable for a variety of surface active applications. The increasing demands for alternative energy generation have significantly promoted the rational design and fabrication of a variety of 2D nanomaterials since the discovery of graphene. In 2D nanomaterials, the charge carriers are confined along the thickness while being allowed to move along the plane. Owing to the large planar area, 2D nanomaterials are highly sensitive to external stimuli, a characteristic suitable for a variety of surface active applications including electrochemistry.

“…[6][7][8] Recently, nanoarchitectonics has been applied in many research fields such as nano/molecular-scale control, fabrication and synthesis of nanostructured materials, more specifically in sensors and biological/biomedical applications. 9,10 Nanoarchitectonics is a new concept for the fabrication of functional material systems through harmonization of various actions including atomic/ molecular-level manipulation, chemical reactions, self-assembly and self-organization and their modulation by external fields/stimuli. 11,12 From that concept, major efforts are now devoted to develop novel HCV diagnostic methods, [13][14][15][16] especially employing electrochemical immunosensors.…”

Interdiffusion at Room Temperature in Cu-Ni(Fe) Nanolaminates

“…Nanolaminates, functional multilayers, and their 2D unit materials are of general importance to fields such as improvements in fracture toughness for medical application [9], energy storage and battery anodes using electrochemical nanoarchitectonics [10,11], and magnetic materials with tunable in-plane anisotropy [12]. The relevance of interdiffusion in nanolaminates is of great importance regarding these applications as well as many others for assessing the robustness of structure in the context of maintaining performance over lifetime use.…”

Cytotoxicity of Group 5 Transition Metal Ditellurides (MTe2; M=V, Nb, Ta)

“…To date, a vast range of 2D nanomaterials have been reported;s uch examplesi nclude transition metal dichalcogenides( TMDs), graphitic carbon nitride (g-C 3 N 4 ), black phosphorus, and hexagonal boron nitride (h-BN). [2][3][4][5][6][7][8] Among2 Dn anomaterials, TMDs are deemed to be one of the most studied layered compounds due to their extraordinary electrochemical properties.
