      New Material Sensor Platform

      Colorimetric Sensor Platform (CSP) : platform technology based on natural color change by diffraction in response to external stimuli

      • Morpho butterfly MORPHO BUTTERFLY
      • Opal OPAL

      • Peacock Feather PEACOCK FEATHER

      [ Mimicking diffraction structure exhibits natural colors ]

      CSP 01

      Development in two forms for multipurpose use

      • film type (on substrate)

        pH responsive hydrogel sensor

      • sphere type (free standing)

        temperature responsive hydrogel sensor

      CSP 02

      Application examples for non-powered self-diagnosis equipment

      • Colorimetric sensor array of glucose level, pH, body temperature, and ionic strength, etc.

        Each sensor operates with different principles, while being integrated on a single chip.

        Porous μ–needle array film is attached underneath the sensor for body-fluid extraction.

        Colorimetric data captured & processed by smart phone application.
