Gold nanoparticle-based colorimetric assay for selective detection of aluminium cation on living cellular surfaces.
A colorimetric assay based on pentapeptide (CALNN) functionalized gold nanoparticles exhibits high sensitivity and selectivity for detection of aluminium cation (Al(3+)) both in aqueous solution and on living cellular surfaces under physiological condition.
