Introduction
Nano-silver has a broad spectrum of antibacterial properties and is widely used in the biomedical field. Biological Effects and Use of Nanosilver Products
The physicochemical properties of nanosilver materials are closely related to [1-4], such as particle size and particle size distribution, morphology, and surface properties. The physical and chemical properties of nanosilver materials
Quality characterization involves the characterization method of commonality, so this standard is formulated.
The physicochemical properties suggested by this standard include the average particle size and particle size distribution, zeta potential, pH, UV absorption absorption maximum absorption
Peak, total silver content, silver valence. This standard mainly refers to the International Organization for Standardization Nano Standards Technical Committee (ISO /TC229) promulgated
The relevant standards [5-6] and the National Nanotechnical Characterization Laboratory under the National Cancer Institute (Nano-
technologyCharacterizationLaboratory, NCL) published related standard characterization methods, and nano-silver biological effect analysis
Physical and chemical characterization methods commonly used in academic literature. Although some physicochemical properties are closely related to biological effects, such as surface functional groups and aggregation processes,
Degree, but there is no corresponding standard method, so the characterization of such physical and chemical properties is not included in this standard.
