摘要

Nanotechnology, and particularly branches of metal nanoparticles (MNPs) have emerged as revolutionary fields of tremendous impact in terms of biomedical, environmental and industrial applications. The review summarizes recent developments in the synthesis, characterization and applications of MNP with emphases on their novel physicochemical properties which can be applied to provide innovative solution in drug delivery, diagnostics, catalysis, and environmental remediation. Despite the massive potential of MNPs, concerns regarding their toxicity, environmental persistence, reproducibility of synthesis, and regulatory complications hinder their broad application. The bibliometric analysis depicts that the MNPs research field is developing briskly, which indicates both the interdisciplinary nature of MNPs research and the increased translational focus. By outlining the possible problematic nature of MNP technologies this review indicates that a concerted attempt is needed to address these concerns in which responsible development is promoted as a means of offsetting scientific advancement with social and ecological considerations.
