Nanotechnology – Revolution in the Field of Medicine

In the recent years, there has been a tremendous development in the field of nanotechnology. Nanotechnology is a field of applied science, which deals in building machines and bots at microscopic levels. Due to development in nanotechnology, there have been many developments in various fields of science, especially in the field of medicine.

 

With the help of nanotechnology, carrying out a complex heart surgery is very much possible. Doctors have started making use of nanobots to cure certain diseases. These nanobots also help in rectifying certain disorders in the human body.

 

Nanotechnology in Drug Development:

 

Recently, scientists are developing effective and better drug delivery systems using nanotechnology. Scientists are using nanoparticles to design a drug delivery system that may improve the pharmaceutical and therapeutic properties of a drug and help better processes such as Drug screening. Nanaoparticles have remarkable properties that drastically enhance the drug delivery. Due to their microscopic sizes, nanoparticles get an easy access in the cells.

 

There are numerous developments in the drug delivery owing to nanotechnology. One such development using nanotechnology is the transfer of drugs into the cytoplasm of cells through the cell membrane. This is an important development, because to hinder certain diseases from the body, the drug needs to enter the cell membrane.

 

 To make a drug molecule effective in the body, it needs a triggered response. To do so, scientists are using nanotechnology. Scientists are developing drugs using nanotechnology that automatically activate, once they enter the human body.

 

Many researchers believe that it is possible to develop a drug delivery system that may prove beneficial in treating cancer and infectious diseases using nanotechnology. By far, they have identified six types of nano-enabled delivery systems that have considerable potential in treating cancer and other infectious diseases.

 

With the help of nanotechnology, scientists have developed injectable drugs, which are more pleasing for the patients, who receive them and at the same time are easy to administer. Better opportunities are coming up in the development of implantable delivery systems, due to the use of nanotechnology, especially in terms of injectable drugs. 

 

With so much of development taking place in the field of drug delivery systems, researchers believe that in the near future nano-enabled medicines will have a tremendous evolution and will produce true nanomedicines.

Nanotechnology And Photovoltaics Trends & Market Potential

Nanotechnology, shortened to “Nanotech”, is the study of the control of matter on an atomic and molecular scale. Generally nanotechnology deals with structures of the size 100 nanometers or smaller, and involves developing materials or devices within that size.

Nanotechnology is very diverse, ranging from novel extensions of conventional device physics, to completely new approaches based upon molecular self-assembly, to developing new materials with dimensions on the nanoscale, even to speculation on whether we can directly control matter on the atomic scale.

Although nanotechnology is a relatively recent development in scientific research, the development of its central concepts happened over a longer period of time.

Photovoltaic (PV) is the field of technology and research related to the application of solar cells for energy by converting sun energy (sunlight or sun ultra violet radiation) directly into electricity. Due to the growing demand for clean sources of energy, the manufacture of solar cells and photovoltaic arrays has expanded dramatically in recent years.

The coming together of these two technologies has become the talk of the town lately.

This report looks at how nanotechnology is changing the field of photovoltaic innovation.
From the basics of nanotech to the basics of photovoltaic, this report looks at how nanotech is making possible new developments in the solar PV industry.
