In the fields of chemistry and biology, TRIS base(tris (hydroxymethyl) aminomethane) has long been an indispensable buffer in laboratories. It is widely used in biochemical experiments, molecular biology, protein purification, electrophoresis and other experiments. The buffering range of TRIS is between pH 7.0 and 9.2, indicating good buffering ability. However, the functionality of TRIS in the laboratory goes far beyond this. In recent years, with the rapid development of nanomaterials in the biomedical field, the application of TRIS in the synthesis of nanomaterials has gradually attracted the attention of researchers, especially in the green synthesis of gold nanoparticles.

The advantages of using TRIS as a reducing agent to prepare gold nanoparticles

Gold nanoparticles have shown great potential in fields such as biosensing, medical imaging, and drug delivery due to their optical, electrical, and catalytic properties. Traditional methods for synthesizing gold nanoparticles, such as sodium citrate reduction, phase transfer, and seed growth, have advantages in controlling nanoparticle size and morphology, but often require the use of toxic reagents such as sodium citrate and thiol compounds, which have certain limitations.

TRIS, as an organic compound with three hydroxyl groups, exhibits excellent reducing ability under alkaline conditions. When TRIS reacts with chloroauric acid (HAuCl ₄) in an alkaline environment of sodium hydroxide, it can effectively reduce Au ⁺ to Au ⁰, thereby generating stable gold nanoparticles. Compared with traditional methods, TRIS as a reducing agent not only has the characteristic of no pollution, but also can obtain nano gold particles with controllable size and good dispersion without the need for additional stabilizers.

New ideas for green synthesis to promote the application of nanomaterials

TRIS, as a reducing agent, has the advantages of mild experimental conditions, simple operation, and low cost in synthesizing gold nanoparticles. By adjusting parameters such as reaction temperature, TRIS concentration, pH value, etc., the size of gold nanoparticles can be accurately controlled, providing a good foundation for subsequent biological modification and functionalization. Compared with other green synthesis methods, the experimental conditions are milder and easier to operate. This provides more possibilities for the synthesis of green, pollution-free, low toxicity, low-cost, and highly biocompatible gold nanoparticles.

Future prospects: Integration of green chemistry and nanotechnology

With the continuous deepening of the concept of green chemistry, researchers are paying more and more attention to environmental issues in the experimental process. The application of TRIS in the synthesis of gold nanoparticles not only embodies the concept of green chemistry, but also provides a more efficient path for the preparation of nanomaterials. In the future, with further research on the synthesis mechanism of TRIS, its application prospects in the field of nanomaterials will become increasingly broad.
