Emergence of Nanotechnology and its application in the field of healthcare has opened a new dimension in medical treatment and diagnosis. Nanomedicine, besides detecting diseases at an early stage, helps in preventive intervention and acts as prophylaxis of chronic and for acute disorders. It is considered to serve as an alternative to the main stream medicine market.
There are plenty of reasons why Nano-technology is making major brake-though in the health and medicine domain. Acceptance of Nanomedicine is mounting due to headways in its functionalities of using nanomedicine and its formulations. Mainly due to:
• Helps to reduces the drug dosage as it increases the possibility of drug potency.
• Patients can easily change from immediate release formulations to modified release formulations.
• It does not use any toxic solvents.
• It can help to increase dissolution.
• Makes use of engineered devices and avoids nano-structures.
Top 6 Nano technology used in nanomedicine treatments and are getting accepted:
Vivo imaging technology
Vivo imaging technology is a tool which uses nanoparticle contrast agent’s images like ultrasound and MRI and helps to produce improved distribution and contrast. This will further accomplish self-assembled biocompatible nanodevices that will detect, evaluate, treat and report automatically to the clinical doctor.
Nanotechnology using a chip uses magnetic nanoparticles which are used to label specific molecules, structures of microorganisms. It is further used for detection of genetic sequence. The technology is also used for analysis of nucleic acids which helps in converting strings of nucleotides into electronic signatures.
Magnetic micro particles
Magnetic micro particles help in separation of cells and proteins from complex media. It helps in removing of different noxious compounds like toxins, pathogens other and proteins from blood. The technology is also used to remove larger compounds of dialyzable.
Nanotechnology tissue engineering
Nanotechnology is used for tissue engineering which helps to reproduce damaged tissue by making use of nanomaterial scaffolds. Tissue engineering will replace age old treatments like artificial implants in the future. It makes use of nanoparticles like graphene, carbon nanotubes and molybdenum disulfide for reinforcing and to fabricate mechanically strong biodegradable polymeric nanocomposites.
Neuro-electronic interfacing help in interfacing computers to the nervous system. the technology builds molecular structure which will control and detect nerve impulses using an external computer. The wiring of the structure will be positioned precisely in the nervous system. The structures which provide interface are compatible with the body’s immune system.
Nanoparticles that ranges between 3 to 200 nanometers, makes them feasible to get injected directly into the tumour accessing the cancers cell, or injected in the proximity in combination with antibodies which targets cancer cells. The procedure stands like- Iron oxide nano-particles coated with bio-compatible substances are inserted in the tumour. These iron oxide nano-particles are heated using an alternating magnetic field, which in turn kills the tumour and other cancer cells doing feeble damage to the surrounding tissue.
Nano-medicine helps to enable site-specific targeting and enables free movement within the blood-brain barriers. It helps in felicitating diagnostics as well as therapeutics usage simultaneously. It has unique physicochemical properties which can be exhibited by nano-particles which make them highly suitable in drug delivery systems and are used for targeted therapeutic action.
