How Nanomedicine can change the future of medicines
Nanomedicine is a branch of medicine that applies the knowledge and tools of nanotechnology to the prevention and treatment of disease. Nanomedicine involves the use of nanoscale materials, such as biocompatible nanoparticles and nanorobots, for diagnosis, delivery, sensing or actuation purposes in a living organism.
How does a Nanomedicine works ?
Nanomedicine is simply the application of nanotechnologies in a healthcare setting and the majority of benefits that have already been seen involve the use of nanoparticles to improve the behavior of drug substances.
Working at the nanoscale with structures that are usually 10-100 times smaller than a body’s cell but only little larger than molecules makes possible the treatment of several diseases at the molecular level.
It works are based on molecular or atomic level and the apparatus designed are acutely at small scale, this provides speed and high performance with low maintenance. Some of the inventions of nanomedicines such as the biosensor, nanoelectronic instruments, pacemakers, ECG machines and advanced forms like nanorobots and nano instruments are used widely by the surgeons.
It works by injecting nanoparticles into the body, this can be used to deliver medicine, diagnose and treat different diseases and repair the damaged cells.
Applications of nanomedicine:
- Drug delivery: Nanomedicines can play an important role in ensuring enough of the drug enters the body, that drug that does enter stays in the body for long periods and is targeted specifically to the areas that need treatment. As the drugs have a very little solubility in water and the human body struggles to absorb enough to treat the condition and sometimes may lead to side effects.
- To fight against diabetes: Nanoparticles are being developed as imaging contrast agents to assist in the early diagnosis of type 1 diabetes. Glucose nanosensors are being incorporated in implantable devices that enable more accurate and patient-friendly real-time tracking of blood glucose levels, and are also providing the basis for glucose-responsive nanoparticles that better mimic the body’s physiological needs for insulin. Finally, nanotechnology is being used in non-invasive approaches to insulin delivery and to engineer more effective vaccine, cell and gene therapies for type 1 diabetes.
- Cancer diagnosis and treatment: Tumor biomarkers are used to detect earlier diagnosis of cancers.An accurate mapping of lesions can be done by Iron Oxide Nanoparticles.Using Nano-Therm therapy to overheat cells and destroy them. This could increase the survival rate of cancer patients.
- Cell repair: Nanorobots could actually be programmed to repair specific diseased cells, functioning in a similar way to antibodies in our natural healing processes.
Advantages of nanomedicine:
- Faster diagnosis of many ailments.
- More precise treatments of conditions such as cancer.
- Repair tissue deep within the body.
- Target only diseased organs without destroying healthy tissue.
- Reduced negative effects of drugs and surgical procedures.
- Cost-effectiveness of medicines.
The use of nanomedicines could revolutionize the way we detect and treat damage to the human body and diseases in the future.
Over the coming years, the benefits of nanomedicine and new diagnostic tools will be felt by an increasing no. of patients with significant impact on global health.
