Description

A Korean university has developed the environmental contamination factor analysis microfluidic chip and a manufacturing method thereof comprising the silicon Nano-particle in which the surface area is improved to three dimensional structure since it introduces the silicon Nano-particle within the microfluidic chip in which the pillar pattern is introduced and the silicon Nano-particle is fixed to the pillar pattern and the color change is by the naked eye sensible. This technology presents a microfluidic chip combined with an image recognizing mobile-app for colorimetric sensing for a wide range of harmful chemicals such as heavy metal ions and environmental toxicants. 3-dimensional surface with high surface area introduced by vertical micron pillars (10-1000 microns in height, and 10-100 microns in diameter) and silicon nanoparticles (50-500 nm in diameter) into microchannels inside the microfluidic chip. The 3-dimensional corrugated structure provides enhanced interaction with analytes and improved color changes at low concentration of analytes, enabling to utilize them to the mobile application with various statistical approaches for an universal use of environmental chips. This technology is suitable for (but not limited to) the following products/application: • Portable environmental chip and application • Establishing ‘Environment Map (E-MAP)’ • Mobile application and create advertising earnings The extension of its application in various fields, by applying a new probe to environmental chip with groceries and medical devices, is currently under consideration. Under the license agreement, this technology could be licensed to with products incorporating features that result in improving the low sensitivity of a conventional colorimetric sensor.

Advantages and innovations

• Increased sensitivity for the colorimetric sensor through the introduction of the 3-dimensional corrugated surface with a high surface area by vertical micron pillars and silicon nanoparticles. • The device is not-expensive due to the cheap main component (PDMS). • The system can be easily manipulated by unskilled people due to an automatically controlled analytic system with our cloud-based statistical analysis

How it works

  • Tell us about yourself
  • We’ll discuss with you
  • We put the right partners in touch

EEN help you find the right partner, rather than you going it alone.

Our role is to review and collate the most suitable submissions, and then send them to the client who posted the opportunity. We consult with you, and the client, to make the process professional and easy.

These are live opportunities. Your registration of interest on the site is just like a professional approach to a business at a networking event. To stand the best chance of success, make your submission really sing. Sell why the client who posted the opportunity should work with you. Excite them. Ask questions. Try and avoid copy and pasting words from elsewhere.

Once the client has chosen their partner, we'll introduce them over email and keep in touch with both parties to see how it's going. Sometimes things progress quickly. Sometimes because of changing priorities for either party, things progress slowly, but you never know - your next big business break could start right here.
