Nano Particles,
Huge Impact.

Towards a society where all resources circulate smoothly and are utilized optimally

Continuously commercializing breakthrough technologies at unprecedented low costs

We focus on simple and affordable technologies accessible to everyone, rather than expensive and complex solutions limited to a select few.

We prioritize practical problem-solving over theoretical technology, constantly identifying and commercializing solutions that society truly needs.

Technology & Products

Solving diverse challenges through compound nanoparticle technology.

Our proprietary nanoparticle technology, developed at Tohoku University, achieves stable nanoparticle formation of compounds that was previously challenging. The dispersion, miniaturization, and increased surface area of nanoparticles in solution enable property enhancement and new applications.

Proprietary Nanoparticle Technology

Precise control of compound particle size at nanometer scale.

  • High dispersibility & sensing sensitivity
  • Compatible with various organic materials

Nanoparticle Properties

Achieving nanoparticles with high dispersibility and stability.

  • Ideal for high-sensitivity sensing applications
  • Easy mass production & scale-up

Solutions

Real-time Detection of PFAS in Water

By nanoparticulating organic dyes that change color in response to PFAS and dispersing them in water, highly sensitive detection of low-concentration PFAS is achieved through color change alone.
Applicable to real-time PFAS detection and monitoring of tap water, wastewater, and environmental waters.

Safe, Low-Cost Next-Generation Battery Development

A rare-metal-free electrolyte using organic nanoparticles drives the commercialization of safe, low-cost next-generation redox flow batteries.
Contributing to long-duration storage infrastructure that supports the mass adoption of renewable energy.
