摘要：

Colloidal nanoparticles, in particular gold nanoparticles and quantum dots, can be used in a variety of different assays for optical sensing of small ions in solution. In this review, different detection principles are introduced and their potential use for detection in biological samples (such as intracellular sensing) is discussed. optical excitation
