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 Introduces Nanorobots (reproduction)

Nanotechnology’s invention of nanorobots is theoretical microscopic devices that calculated on the scale of nanometers (1 nm equals one millionth of a millimeter). When fully realized from the hypothetical stage, they would work at the atomic, molecular and cellular level to perform tasks in both the medical and industrial fields that have heretofore been the stuff of science fiction.

In past generations some body identified with cancer may be offered a new option to chemotherapy (the traditional cure of radiation, which kills not just cancer cells but healthy human cells too, causing hair loss, exhaustion, sickness, depression, and a host of other symptoms as well). A doctor enthusiastic towards nanomedicine would give the patient an injection of a particular kind of nanorobot, which would seek out cancer cells and tear down them, dismissing the disease at the source, leaving healthy cells unharmed. The amount of the adversity to the patient will fundamentally be a stab to the arm. A person experiencing a nanorobotic treatment can hope to have no alertness of the molecular devices working inside them, other than fast betterment of their health.

Nanomedicine’s nanorobots are actually very tiny that they could with no trouble pass through the human body. Nanotechnology scientists report the external of a nanorobot would probable are constructed of carbon atoms in a diamondoid structure as of its motionless properties and other strength. Super-smooth surfaces would further lessen the possibility of activating the body’s resistant system, permitting the nanorobots to go about their business without hindrance. Glucose or natural body sugars and oxygen may be a foundation for force, and the nanorobot would have other biochemical or molecular parts depending on its task.

According to present theories, nanorobots would possess as a minimum basic two-way communication; would respond to acoustic signals; and would as well be able to get power or even re-programming instructions from an outside source via sound waves. A system of particular stationary nanorobots may be deliberately placed all through the body, logging every active nanorobot as it passes, and then reporting those results, permitting an line to keep pace of all of the devices in the body.

Nanobiotechnology,a Quantum Scientific Approach in 21st Century

Nanobiotechnology,a quantum scientific approach in 21st century

Imagination is the key in human life and is the main force behind every development of human lifestyle. Considering the impact of science and technology on the human race, it is natural to think ‘Nothing is Impossible’.

Biotechnology is the application of biological research techniques to develop immense products for mankind. Whereas, nanobiotechnology is the application of nano-scaled tools to biological systems and the other is the use of biological systems as templates in the development of novel nano-scaled products. Simply a nano-biotechnology is the complex of nanotechnology and biotechnology. Each of these technologies has a tremendous impact by itself and therefore when they complement each other it results in efficacious fourth dimensional solutions.

Nanotechnology used in biotechnology usually called nanobiotechnology is definitely a life-saving innovation that has come as a boon to mankind. It involves the creation and use of materials and devices at the level of molecules and atoms for the development of Nanomedicine, Nanosensors, Nanofluidics and Nanofabrics. It is a valuable contribution of the profound research by scientists and engineers to create new systems with novel functionalities.

Nanomedicine is one of an offshoot of nanotechnology, refers to highly specific medical intervention at the molecular level for curing disease or repairing damaged tissues, such as bone, muscle, or nerve. The existing means of intake of drugs orally or through injections are becoming moderately effective but can be extremely painful due to the non-availability of accurate diagnosis. The concept of nanomedicine involves the newer methods to deliver drugs at the right place, time, and amounts in the body. Scientists and engineers have developed new systems where the human-body parameters are monitored using a techno-monitor (semiconductor chip) that is placed inside a human body. These chips are the “nano” machines which are compatible with living tissues and can be safely operated inside the body.

For example: When a patient is being treated for diabetes, the semiconductor chip monitors the blood-sugar levels and passes on the information to the device outside of the body. The external device, in turn, instructs the semiconductor chip that acts as the drug delivery system, to release the right amounts of insulin into the blood, thus causing less or no side effects to the patient.

The approach of nanomedicine is versatile and will completely revolutionize the diverse branches of medicine in near future. It involves the application of nanoparticles for cancer imaging and therapy, drug delivery for prostate cancer and nanowire devices for virus detection and cancer screening too. Thus, nanomedicine is simply the preservation and improvement of human health using molecular tools and molecular knowledge of the human body.

Nanofabrication is the design and manufacture of devices with dimensions measured in nanometers. One nanometer is 10-9 meter, or a millionth of a millimeter. It is of high interest to computer engineers as it opens the door to super-high-density microprocessors and memory chips. It has been suggested that each data bit could be stored in a single atom. Carrying this information further, a single atom might even be able to represent a byte or word of data.

Nano sensors can be prepared by engineering the biomolecules, to recognize a wide variety of targets, including small molecules and specific proteins. Researchers have created DNA-based sensors for nano-tongues and nano- noses.

Nanotechnology shares a wide range of applications right from high-density data for detecting DNA sequence to improve taste and variety of fruits and vegetables nanofluidics. On the commercial front, nanotechnology has enhanced every field in science, engineering, and technology, thus giving high efficiency and profitability of human existence.

This is all being addressed through nano-biotechnology.
