Metallic nanomaterials in cancer theranostics: A review of Iron oxide and Gold-based nanomaterials

The role of nanotechnology in cancer treatment and diagnosis, especially in the creation of new generation cancer diagnostic and therapeutic instruments, has attracted a lot of attention in recent years. Attempts to incorporate therapeutic and diagnostic properties in a single efficient nanomedicine solution have been made in large numbers. This concept, coined "theranostics," is a smart nanosystem capable of diagnosing, successful dissemination, and therapeutic reaction tracking. By integrating clinical functionality with molecular imaging, therapeutic interventions can be useful in the selection of medication, treatment preparation, objective response control and follow-up planning based on the specific molecular characteristics of the disorder. Here, we summarize a number of recent efforts in this regard and demonstrate that therapeutic systems and techniques have considerable potential for tracking and optimizing nanomedicine-mediated drug targeting.
