Green synthesis of strontium oxide nanoparticles and strontium based nanocomposites prepared by plant extract: a critical review

Recently, strontium oxide nanoparticles (SrO NPs) have become the center of attention due to potential features and promising applications. The physicochemical approaches possess many limitations including extreme experimental conditions, highly complex instruments and use of hazardous chemicals. An eco-friendly and sustainable approach from biogenic sources for formation of SrO NPs is an emerging trend nowadays to effectively replace conventional approaches. This review study all those aspects that facilitate the reader for understanding all biogenic approaches of SrO NPs for their use in different applications with less toxicity issues. In this study, firstly we discuss in detail about plant and other biogenic assemblies based on the synthesis of SrO NPs after which parameters affecting the synthesis of SrO NPs are discussed and finally excellent biomedical applications of SrO NPs along with mechanism are summarized. The literature also showed that green synthesized SrO NPs are highly biocompatible in nature and showed excellent anti-bacterial, anti-oxidant and anti-fungal potential. Hence, this study will provide an understanding to researchers about recent trends for the formation of SrO NPs through different biogenic assemblies and their potential biomedical applications.
