Abstract:
Supramolecular capping of cucurbit[5]uril (CB[5]) by gold nanoparticles has been achieved via a facile reduction of an aqueous solution of HAuCl(4) by NaBH(4) in the presence of various amounts of CB[5]. The resultant assemblies were very stable in solution, and were found to form dynamic aggregates consisting of a controllable ratio of singly and doubly capped CB[5].

01:09Colloidal precipitates
The high insolubility of some precipitates can result in an unfavorable relative supersaturation. This can lead to colloidal particles with a large surface-to-mass ratio, where adsorption is promoted. For instance, in the precipitation of silver chloride, silver ions are adsorbed on the surface of the colloidal particles, forming a primary layer. This layer attracts ions of opposite charge (such as nitrate ions), forming a diffuse secondary layer of adsorbed ions. This electric double layer...
01:06Coagulation
Colloidal solids are solid particles suspended in solution. They are usually negatively charged, attracting a compact primary layer of positively charged ions, which attract more counterions to form an electrical double layer. Electrostatic repulsion between the charged double layers prevents the particles from colliding, stabilizing the colloids. These solids are often undesirable because they can contain toxins that are difficult to remove. Coagulation is a technique that helps aggregate and...
