We infered that this new absorption band was associated with the effect of charge - transfer transition between adsorbates and colloidal silver particles, not the effect of the surface plasma resonance due to the silver particles aggregation which was usually attributed to in previous research work
我們將其歸因於與納米銀顆粒表面間的電荷轉移效應（ ct ） ，而非通常所認為的因銀膠凝聚而產生的表面等離子體共振吸收效應。
Viruses are colloidal particles.
One case is that of tiny dust particles or colloidal particles suspended in a fluid.
A sol that consists of solid particles suspended in a liquid is a colloidal suspension.
Clays are produced by mechanical and chemical weathering and primarily colloidal in size.
