77-86-1 Tris Hydroxymethyl Aminomethane,
Green Agent Tris Hydroxymethyl Aminomethane,
CAS 77-86-1 Tris
Tris (hydroxymethyl) aminomethane Tris (TRIS)—a rare green agent TRIS(CAS 77-86-1)
Tris (TRIS)—a rare green reducing agent
As a researcher or salesperson in the field of chemistry or biology, we know TRIS (Tris(hydroxymethyl)aminomethane) very well. It is widely used as a buffer for biochemical and molecular biology experiments. The effective buffer range of TRIS buffer is pH 7.0~9.2. In addition, TRIS (CAS 77-86-1) is also an intermediate of surfactants, vulcanization accelerators and some drugs.
But in the following paragraphs, we will introduce the function of TRIS as a good reducing agent for the preparation of gold nanoparticles. Since it has three equivalent hydroxyl groups, under the alkaline condition of sodium hydroxide, the chloroauric acid solution can be reduced to prepare stable gold nanoparticles, which is non-toxic and non-polluting.
At present, the classic methods for synthesizing gold nanoparticles include sodium citrate reduction method, phase transfer method and seed growth method. These methods are most likely to modify the surface of gold nanoparticles with biomolecules, but the preparation and modification process has a certain degree of toxicity. In order to reduce the toxicity of gold nanoparticles to organisms in experiments and make them better used in the field of biomedicine, in recent years, researchers have devoted themselves to developing new green reduction methods.
When TRIS is used as a reducing agent to reduce the chloroauric acid solution under alkaline conditions, relatively stable gold nanoparticles can be obtained without adding other stabilizers. By adjusting the experimental conditions, gold nanoparticles of different sizes can be prepared. Compared with other green synthesis methods, the experimental conditions are more gentle and easy to operate. It provides new research ideas and theoretical basis for the synthesis of green, pollution-free, low toxicity, low cost, and high biocompatibility gold nanoparticles.

In summary, the Tris ultrasonic method reduces chloroauric acid, the experimental operation is safe and simple, the reaction conditions are mild, and it will not cause pollution and damage to the environment. It is a "green" reduction method. Using tris(hydroxymethyl)aminomethane (Tris) as the reducing agent, reducing the chloroauric acid solution under alkaline conditions, by adjusting the ratio of Tris and NaOH, the reaction time and adding stabilizers, stable gold nanoparticles can be synthesized.
