Research

Establishment of interdisciplinary Monodzukuri (manufacturing) basic technology in micro- and nano-scale. Novel micro- and nano-structuring techniques for manufacturing MEMS/NEMS devices, and MEMS-based platform for in vitro manipulation and analysis of living cells for supporting the creation of innovation in life science and biotechnology.

Theme1:Innovative genetic diagnostic devices based on microfluidic technology

Overview
Multiplexed genetic diagnostic device

To proactively address future pandemics, there is an urgent challenge to establish a rapid and easy sample-to-answer platform for the simultaneous detection of multiple nucleic acid targets across multiple samples in a single operation. This capability is crucial for protecting human life and well-being, and for ensuring a safe and resilient society. Moreover, the demand for genetic testing is expanding across diverse fields, including the detection of food allergens and foodborne pathogens to ensure food safety and sanitation, as well as the inspection of crop diseases and pests to support a sustainable food supply. Therefore, we are developing (1) microfluidic devices for multiplexed genetic diagnosis across multiple samples, (2) logarithmic parallel dilution microfluidic devices for rapid and reliable detection of target nucleic acids, (3) microfluidic digital LAMP devices for absolute quantitative detection of targeted nucleic acids, and (4) microfluidic devices for automated nucleic acid extraction.

Theme2:A chip-based system for massively parallel manipulation and analysis of single cells (Cellular MEMS)

Overview
MEMS-based platform for in vitro manipulation and analysis of living cells for addressing fundamental questions in biological systems.

A thorough understanding of cellular functions is a prerequisite for realizing biological applications such as medical diagnostics, drug discovery, and tissue engineering. Therefore, I have been developing novel MEMS devices for massively parallel manipulation and analysis of single cells. These include (1) an array of out-of plane, hollow nanoneedles capable of introducing desired biomolecules (DNA, proteins, etc.) into living cells and extracting biomolecules expressed in the cells, (2) a micromanipulator array capable of massively parallel manipulation of single living cells for 2D/3D cell patterning, (3) a cell culture microdevice actuated by piezoelectric thin film for on-chip regulation of cell functions, and (4) non-damaging measurement system for monitoring cell-shape dynamics based on scanning ion conductance microscopy (SICM).

Theme3:Novel scanning probe microscopy techniques for cellular function analysis (Bioprobe)

Overview
Multi-functional biological scanning probe microscope.

With the aim of introducing novel atomic force microscope (AFM) applications to cellular function analysis, I have been developing a newly designed AFM probe (bioprobe): this enables intra- and extra-cellular delivery of biomolecules (DNA, proteins, etc.). Moreover, the bioprobe will provide other useful functions, such as scanning ion conductance microscopy (SICM) for non-damaging imaging of biological cells, and tip-enhanced Raman scattering (TERS) spectroscopy for quantitatively study on dynamic processes inside living cells. Therefore, I can provide a method for correlation analysis of cellular functions with high spatial and temporal resolution.
