To understand the nanomedicine, first, we need to know about the nanotechnology, which is the design and implementation of working structures developed through the atomic, molecular, and supramolecular scale that include the minimum of one feature dimension measured in nanometers.
A nanometer is one-billionth of a meter, this size allows to unveil novel and remarkably enhance chemical, physical and biological features, phenomena and procedure.
Nanotechnology can be effective in a number of fields including medicine, where the term define as the Nanomedicine.
Nanomedicine is an application of nanotechnology, which is use to identify, monitor, repair, construct and treatment of the human biological method at the molecular level, through the nanostructures and advanced nanodevices.
Further, nanomedicine includes the use of nanoscale accessories such as nanorobots and biocompatible nanoparticles, to prevent, identify and treatment the health related problems in living things.
The National Aeronautics, the Space Administration, and the National Cancer Institute, USA are concerning to design and develop nano-sized technologies which would be capable of detect, diagnose and treat disease.
A Noble Prize winning chemist at Rice University, USA, Richard Smalley showed his view to the congress on how the features of nanotechnology can transform medicine; after twenty years, we can have advance engineered drugs, which will target to heal the mutant cancer cells in our body.
Italian and French research team have a completely new approach to deal anticancer and antiviral nucleoside analogs to squalene, a biochemical precursor to the network of steroids, the research team studies the self-organization of amphiphilic molecules in water.
These nanotechnologies highly concern to deal with the anticancer activity in vitro of human cancer cells.
As per the European Medicines Evaluation Agency Source, the majority of present applications of nanotechnology to medicine is supportive to drug delivery to make available new modes of action, also making the targets more specific of existing medical substances.
Cardiovascular disease (CVD)
CVD includes different disorders of blood vasculature and heart, also stroke; the nanotechnology in medicine by using nanoscale dimensions of the system.
Nanotechnology includes a convergent discipline, where the margins distinguishing different research areas like physics, biology, chemistry engineering, and mathematics etc. become blurred.
Cardiovascular nanomedicine aims to survey and identify existing challenges in CVD and also to improve therapy through advancing ex vivo and in vivo biomarkers detection and imaging, and also by specific modern drug delivery and tissue creation.
Nanoparticles as therapeutics can passes to the aimed sites, including targets, which is really hard to reach by standard drugs. For instance, if a therapeutic can attach chemically to a nanoparticle, later it can track to the site of the disease or towards the infected area by radio magnetic signals.
The use of nanomedicine can provide an instant discovery of cancer infection to the doctor than biopsies does. Early and easy detections of cancer-related problems will make less burdensome treatments, as well as enhances the chances of recovery.
Nanomaterials sized from 1 to 100 nm size play a role of functional constituents of bones of nanosized mineral and organic phases.
Nanotechnology represent a smart realm of research and implementation may improve the existence of an implant bone matters by increasing bone cell interactions as well as decreases the patient patient-compliance problems.
The future of dentistry has many positive impacts due to the use of nanomaterials or nanotechnology. In coming days nanodental techniques in tooth repair will also evolve and reconstructive dental nanorobots would be in use with the precise occlusion of specific tubules in a very short time, which will facilitate prompt and quick recovery.
