Introduction
Nano silver materials are an important variety of nano metal materials: In addition to the optical, electrical, magnetic, and thermal effects of general metal nano materials, they also
It has broad-spectrum, high-efficiency, low-toxicity, and antibacterial properties that are not easy to produce drug resistance:
Bacteria daily chemicals, antibacterial public health products, etc: have been increasingly used:
Nano silver particles are not easy to exist stably in the solid phase and have a tendency to agglomerate, so the nano silver particles are often dispersed in the liquid medium during use:
The formation of nano-silver colloidal solution, also known as nano-silver sol:
Nano silver colloidal solution
