Cu2＋ Detection with Gold Nanoparticles by Patterning Colorimetric Strips on a Filter Membrane Assembled in a Microfluidic Chip

We have developed a microfluidic chip for colorimetric CH2＋ detection. In this chip, it is facile to do colorimet- ric Cu2＋ detection based on gold nanoparticles. This method has a dynamic detection range from 0.75 to 50 lamol/L with only 20μL solution including detection reagents and sample. The re...

More Information
Summary:We have developed a microfluidic chip for colorimetric CH2＋ detection. In this chip, it is facile to do colorimet- ric Cu2＋ detection based on gold nanoparticles. This method has a dynamic detection range from 0.75 to 50 lamol/L with only 20μL solution including detection reagents and sample. The result can be readout by naked eye and pho-tographed by digital cameras. With the help of image processing software, we could measure the RGB value and calculate the Blue/Red ratio for more accurate quantification. Tap water could be detected in this portable chip.
