Nanorobots used in cancer treatment

Abstract

Cancer, being one of the most violent diseases of the 21st century, is nothing new. The inability of traditional treatments to target cancer cells only without damaging the healthy tissue is the major cause of numerous side effects, such as nausea, hair loss, or fatigue, that are a result of this care. This review aims to analyze Nanorobots, their roles, and usage in cancer treatment. Nanorobots are microscopic devices designed to perform tasks at the nanoscale, are a promising solution. Their intricate design and functionality have created diverse applications, ranging from drug delivery systems to targeted therapy. These devices ensure accurate targeting of cancerous cells while avoiding damage to healthy ones. Compared to traditional treatment methods, nanorobot-based care boasts greater specificity, long-term effects, and reduced side effects. Even though challenges and issues, such as technical obstacles, safety concerns, and resource constraints, exist, these machines hold extensive promises to be the new standard in cancer care.
