Nanotechnology: A Review on Personalized Cancer Therapy and Diagnosis

Abstract

In the field of cancer Theranostics, nanotechnology has become a game-changer by combining therapeutic and diagnostic properties into a single platform. The role of several nanomaterials, such as carbon dots, albumin-based nanoparticles, gold Nano shells, quantum dots, and PEGylated multi-functional nanoparticles, in improving cancer diagnosis and treatment is highlighted in this abstract. Semiconductor nanoparticles known as quantum dots (QDs) have remarkable fluorescent characteristics that enable multiplexed cancer cell detection and high-resolution imaging. Because of its adaptable optical qualities, low toxicity, and biocompatibility, carbon dots (CDs) have attracted interest. A single platform is created using PEGylated Multi-Functional Nanoparticles, which integrate multiple technologies. Polyethylene glycol (PEG) surface modification results in these nanoparticles having longer circulation times, decreased immunogenicity, and increased durability. A major development in cancer Theranostics is represented by the integration of quantum dots, carbon dots, albumin-based nanoparticles, gold Nano shells, and PEGylated multi-functional nanoparticles, as this review article briefly explains. These advancements promise to increase clinical outcomes and patient management in oncology by providing tailored therapeutic delivery, individualized treatment approaches, and improved diagnostic precision
