摘　　要：贵金属纳米材料由于其独特的光电化学性能,在分析化学领域应用广泛。但是,纳米粒子在水溶液中不稳定,这在一定程度上限制了贵金属纳米材料的发展,水凝胶载体能够很好地解决此问题。水凝胶具有优异的机械性能、良好的生物相容性和易于改性等特点,在稳定纳米材料的同时,能够提升纳米材料的性质,因此,贵金属纳米粒子与水凝胶复合材料的研究逐渐增多。本文主要对近五年贵金属纳米粒子与水凝胶复合材料的制备及其在分析化学领域的应用进展进行了评述,分析了贵金属纳米粒子与水凝胶的作用机制以及应用优势,并对其未来的发展趋势进行了展望。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 easy 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 analyzed the application advantages of composite materials and their further research orientations.
