Multiple Protein

We have developed a very simple colorimetric sensor array by using only unmodified gold nanoparticles and NaCl salt for discrimination of multiple proteins. The inexpensive and convenient sensor array and the ubiquitous smartphone are coupled to achieve an immediate point-of-care diagnosis without additional devices.
