Nanotechnolgy

Nanotechnology involves manipulating atoms and molecules to give structure new chemical and physical properties.

Nonotechnolgy device have a wide range of application such as electronics , medicines, energy ,textiles and more.

These device typcally have a scale of fewer than 100 nanometer(nm).

A nanometer is very small unit of measurment equal to one billionth of a meter.

Nanotechnolgy refers to any device or product that is created or modified by manipulating matter at the nanoscale.

By controlling atoms and molecules.

Nanotechnology  create material devices and system with unique properties and functions.

Due to very small size they exhibit different physical and chemical properties than the same material at larger scale.

Due to small size nanomaterial have a large surface area-to-volume ratio which can lead to increase reactivity , strength and conductivity.

Nanotechnolgy in health sector

Healthcare is a priority research of nanotechnology to deliver improvement in human health and quality of life.

There are both ethical and safety issued both are addresssed.

Nanomaterial could be applied to improve tissue regeneration like restoring cartilage function to overcome arthritis.

Nanotechnology could also help in the fight against cancer, by developing nanomaterial systems to attack and destroy tumours.

Recent research has investigated the properties of fullerene compounds as antiviral agents to eliminate pathogens and bacteria in place of long-term antibiotic treatments.

Nano-tool kits are also being developed that will use nano-robots to monitor health inside a patient or to act at the sub-cellular level where a disease occurs.

Nano-robots could be introduced through the vascular system, and could be programmed and guided by a surgeon to identify the molecular origins of severe diseases like Alzheimer’s or Parkinson’s, or to perform intra-cellular surgery.

Nanotechnology implants by allowing miniature devices reduced in size and inserted in human body to cure and repair damaged cells.

Nanomedicine, raises high expectations for millions of patients for better, more efficient and affordable healthcare and has the potential of delivering promising solutions to many illnesses. From diagnosis to disease monitoring, going through surgery and chemotherapy or regenerative medicine, nanotechnologies virtually impact all fields of current medicine.

Several areas of medical care are already benefiting from the advantages that nanotechnology can offer. The first nanotechnology-based targeted drug delivery systems are already on the market, others are in clinical trials or, by far the largest part, are under development.
