Bioogically inspired colorimetric nanobiosensor
The purpose of this study is the design and fabrication of label-free immunosensors based on 3D photonic crystals detectable with color change in real time. The proposed sensor will have advantages of the sensors such as shortening of analysis time and cost, enhancement of sensitivity and selectivity, achievement of mobility, so that any body can use it easily by observing the color change. Moreover, the sensor can be operated without any external energy such as batteries, and does not require the electrical wire for supply of energy, so that it is eco-friendly technology and can be installed in clothing, building, and subway and show the various applications.
