Cancer Nanotechnology: A New Revolution for Cancer Diagnosis and Therapy

Abstract

Background: Nanotechnology is gaining significant attention worldwide for cancer treatment. Nanobiotechnology encourages the combination of diagnostics with therapeutics, which is a vital component of a customized way to deal with the malignancy. Nanoparticles are being used as Nanomedicine which participates in diagnosis and treatment of various diseases including cancer. The unique characteristic of Nanomedicine i.e. their high surface to volume ratio enables them to tie, absorb, and convey small biomolecule like DNA, RNA, drugs, proteins, and other molecules to targeted site and thus enhances the efficacy of therapeutic agents.

Objective: The objective of the present article is to provide an insight of several aspect of nanotechnology in cancer therapeutics such as various nanomaterials as drug vehicle, drug release strategies and role of nanotechnology in cancer therapy.

Methods: We performed an extensive search on bibliographic database for research article on nanotechnology and cancer therapeutics and further compiled the necessary information from various articles into the present article.

Results: Cancer nanotechnology confers a unique technology against cancer through early diagnosis, prevention, personalized therapy by utilizing nanoparticles and quantum dots.Nano-biotechnology plays an important role in the discovery of cancer biomarkers. Quantum dots, gold nanoparticles, magnetic nanoparticles, carbon nanotubes, gold nanowires etc. have been developed as a carrier of biomolecules that can detect cancer biomarkers. Nanoparticle assisted cancer detection and monitoring involves biomolecules like proteins, antibody fragments, DNA fragments, and RNA fragments as the base of cancer biomarkers.

Conclusion: This review highlights various approaches of cancer nanotechnology in the advancement of cancer therapy.
