The applications of GNPs and SNPs in medical implant

Abstract

Nanomaterials have been widely utilized in medical implant. This review demonstrates a number of applications of GNPs (gold nanoparticles) and SNPs (silver nanoparticles) in medical implants, including three main aspects, which are dentistry, orthopaedics and soft tissue. Nanomaterials are also known as ultrafine particle materials. Nanomaterials are composed of particles with a size range of 1 ~ 100nm. They are usually in the transition region of the interface between atomic clusters and macroscopic objects. Subsequently, the differences and identities between the applications of two sorts of nanoparticles are compared, along with advantages and limits accordingly and respectively. GNPs are more utilized according to their stability, biocompatibility, coordination functions and promotion mechanism in the human body, while SNPs are more used according to, most significantly antibacterial properties, biocompatibility and coordination functions. And this may path pave the way for those who need to generally decide which nanoparticle is more suitable when it comes to a certain field of medical implant.
