AI Technical Summary
Traditional methods for preparing metal nanoparticles suffer from problems such as uneven hydrodynamic distribution, incomplete reaction, low heat transfer efficiency, wide product size distribution, and poor morphological consistency, making it difficult to meet the requirements of precision catalysis and biosensing. Furthermore, the large batch-to-batch variation in the stirring method limits large-scale production.
The nanoparticle preparation device includes a micro-mixing chip, a reactor, and a separation tank. The micro-mixing chip rapidly mixes and separates the reaction reagents into uniform small droplets. Combined with the temperature control of the capillary and water bath, the uniformity of the reaction and the monodispersity of the product are ensured.
It achieves good uniformity of nanoparticles, small batch-to-batch variation, avoids cross-contamination of reagents, meets the requirements of high-end application fields, and has good stability and uniformity.
