A simple and sensitive method for visual detection of heparin using positively-charged gold nanoparticles as colorimetric probes.

Rui Cao1, Baoxin Li.   

Abstract

The electrostatic interaction between the negatively-charged heparin and the positively-charged gold nanoparticles leads to aggregation of gold nanoparticles and a color change from red to blue in solution, thus providing a simple and visual approach to colorimetric detection of heparin.
