A recently established area of study called nanotechnology aims to create instruments and tools that have precise functions at the cellular, molecular, and atomic capacities. An all-inclusionary size of these materials ranges between 01 to 100 nm. Nanomedicine is the term used to describe the employment of nanotechnology in biomedical research and clinical practice. Theragnostic platforms for cancer have been extensively researched and developed using nanoconstructs made of natural and synthetic polymers. These nanoconstructs come in various structural conformations, including vesicles, hydrogel, micelles, nanoparticles, and hyperbranched polymers. Nanomedicine offers methods for more effective diagnosis by combining developments in adjacent domains including biotechnology, pharmaceutics, and nanotechnology. This results in the identification and characterization of extremely early (pre-evidential) non-invasive diseases and the provision of assessment. The use of paramagnetic iron oxide particles was one of the first uses of nanotechnology in magnetic resonance imaging. When these particles are absorbed by healthy hepatocytes, they may aid in the differentiation of healthy from malignant liver cells. Effectiveness of drug can be enhanced by nanotechnology approaches like increase in surface area, accelerates the rate of disintegration and dissolution. New formulations of nanoparticles will have longer shelf lives and better stability; developing nanoparticle formulations that enhance the absorption of insoluble substances and macromolecules allows for enhanced bioavailability and release rates, which may result in a decrease in the dosage needed and, consequently, fewer adverse effects. Sustaining release characteristics in nanoparticle formulations can enhance patient adherence to medication and dosing schedules. Targeted delivery of drugs using ligand-conjugated nanoparticles.
