General description

The embryotoxicity of gold salt (HAuCl4 · 3H2O) is weaker than the embryotoxicities of a number of other nanoparticles used infor biomedical applications.

Application

Gold(III) chloride trihydrate can be used in the fabrication of colorimetric aptasensor for staphylococcus aureus. It can be reduced with polygala tenuifolia roots (green reducing agent) to produce gold nanoparticles (AuNPs).
