Kawakatsu Lab
Machine-translated · View original
A nanometrology lab whose work ranges from microscopes that image atoms to measurements for assisted reproductive technology.

AboutAbout the lab
Ultrafast, massively parallel, ultrasensitive detection.
The Kawakatsu Lab uses measurement and control technology to develop new scanning force microscopy methods.
The lab also develops a variety of instruments that support nanotechnology.
It also applies the technology it has built up to assisted reproductive technology, working with researchers in medicine, agriculture, and biophysics to measure the propulsive force and vibration of sperm and eggs.
Key terms
- Scanning force microscopy
- A method of examining a sample's surface by tracing it with a sharp tip and measuring the force acting on the tip. The atomic force microscope is one example.
- Probe
- The sharp tip in a microscope that traces the surface of a sample.
- Assisted reproductive technology
- Medical care that handles sperm and eggs to help achieve pregnancy, such as in vitro fertilization.
ResearchResearch themes
The lab uses measurement and control technology to develop new scanning force microscopy methods and instruments that support nanotechnology. It also applies this technology to assisted reproductive technology, studying the propulsive force and vibration of sperm and eggs.
*Illustrative imageAFM that draws atoms in color
The lab studies a color atomic force microscope that reveals differences in composition at the atomic level. It is a microscope that observes samples by vibrating the probe at ultrahigh speed.
*Illustrative imageChemically modified probes
This research applies chemical modification to the probe, the tip that traces the surface of a sample in a microscope.
*Illustrative imageVarious positioning mechanisms
The lab develops a variety of positioning mechanisms as instruments that support nanotechnology.
*Illustrative imageGuiding sperm and measuring their propulsive force
For assisted reproductive technology, the lab works with researchers in medicine, agriculture, and biophysics on techniques for guiding sperm and on measuring the force with which sperm swim forward.
