Preparation of Noble Metal Nanoparticles and Hydrogel Composite Materials and Their Application in Analytical Chemistry

Abstract

Abstract Noble metal nanomaterials are widely used in analytical chemistry due to their unique physical and chemical properties. However, the instability of nanoparticles in aqueous solutions limits the development of noble metal nanomaterials. Hydrogels acting as nanoparticle carriers can solve this problem well. Due to the excellent mechanical properties, good biocompatibility and ease of modification, hydrogels can improve the properties of nanomaterials and provide new application advantages. Therefore, more and more researches focus on the development of noble metal nanoparticles and hydrogel composite materials. Here, we reviewed the preparation principles and application progress of various types of noble metal nanoparticles and hydrogel composite materials in the past five years, and discussed the application advantages of composite materials and their further research orientations.
