Bioinspired colorimetric detection of calcium(II) ions in serum using calsequestrin-functionalized gold nanoparticles



Bioinspired colorimetric detection of calcium(II) ions in serum using calsequestrin-functionalized gold nanoparticles



Angewandte Chemie 48(23): 4138-4141



Seeing is sensing: Calsequestrin (CSQ) functionalized gold nanoparticles undergo calcium-dependent CSQ polymerization, which results in a clear color change (see picture) together with precipitation. The sensing system is specific for Ca(2+) ions and the differences between normal and disease-associated abnormal (hypercalcemia) Ca(2+) ion levels in serum can be distinguished with the naked eye.
