Abstract
Nanoparticles are intensely studied because of their importance in diverse fields of biotechnology, especially in medicine. This paper highlights that waste bark can be a cheap source of biocompounds, with high recovery and functionalization potential in nanoparticle synthesis. Due to their biocompatibility and activity as antioxidant, antimicrobial, and anticancer agents, the green synthesis of metallic nanoparticles is of great importance. This review aims to bring together the diversity of synthesized metallic nanoparticles mediated by bark extracts obtained from different woody vascular plants, the phytoconstituents responsible for the reduction of metal salts, and the activity of metallic nanoparticles as diverse agents in combating the microbial, oxidant, and cancer activity. The literature data highlight the fact that metallic nanoparticles obtained from natural compounds are proven reducing agents with multiple activities. Thus, the activity of natural components in environmental protection and human health is confirmed.
Highlights

Summary
Nanobiotechnology has attracted considerable research, which has had an impact on all life forms [1]. Nanoparticles (NPs) have shown notable advances owing to a wide range of applications in biomedicine, sensors, antimicrobial agents, catalysts, electronics, optical fibers, agricultural, biolabeling, and other areas [2]. Due to their particle size, various shapes, and increased surface area, nanoparticles present very different properties than their bulk materials. The aim of this review is to summarize the literature data (2012–2019) on metallic nanoparticles mediated by plant bark extracts, the nanoparticles’ characteristics, and to discuss their properties, mediated by plant bark extracts, the nanoparticles’ characteristics, and to discuss their properties, including anticancer, antimicrobial, antioxidant, and other activities.
