Nanotechnology used in medicine


By Ankita Chouhan Bsc (GEN)

Nanotechnology is a revolutionary technology to treat various medical diseases. Father of nanotechnology is Richard Feynman. It acts like a miracle for treating chronic diseases such as cancer and AIDS. It focuses on production of cheap medicines, reduce side effects of medicines, treat chronic diseases and manufacture to reduce pain and bleeding during surgery. It works on the principle of targeted drug delivery as a drug that directly injected into the effective cells as large amount of drugs affects the healthy cells.

Carbon nanotubes (CNTs)are very thin cylindrical tubes which can penetrate through the cell membrane and provide drugs to the affected cell. Nano sensor chips are also used to detect early stage of Cancer as it possess thousands of CNTs in it. Other than chips, gold nanoparticles are also used to detect cancerous cells. Doxil, cornel dots (C-dots), abraxane etc are some examples of commercially used drugs containing nanoparticles.

In case to treat AIDS we use HAART (High activity antiviral therapy). As we are aware HIV is not curable but through HAART therapy replication of HIV can be inhibited which in turn leads to a life long treatment. HAART therapy was founded in 1996 which involves a combination of three antiretroviral (ARV) which includes integration inhibitors which prevents the HIV inserting is genetic code into the DNA of the infected cell.

Nanotechnology also plays an important role in bone implantation or replacement surgery. Artificial bones made up nanoparticles are much lighter and stronger than standard artificial bones used in the surgery. With the help of nanotech tools such as Arthroscope are also developed which consists of numerous Nano cameras and Nano lights which help in less time consuming and incision free surgery.

What is Quantum mechanics?-simplified

Definition

The branch which deals with the mathematical explanation of certain factors. Foe example – Heisenberg principle, dual nature of particle and wave relation, etc.

It is a fundamental theory in Physics and one of the famous and complicated too.

Emergence

The theory emerged during the 20th century, at the time when Albert Einstein proposed the general theory of relativity. many scientists contributed for this theory and named in German as ”’Quantenmechanik’ by  Max Born, Werner Heisenberg, and Wolfgang Pauli.

Understanding the Quantum mechanics

Quantum mechanics was a breakthrough for the physics along with the theory of general relativity. Because, before that only classical physics existed which could only explain things in macro levels like astronomy. Afterwards, physicists noticed that there are some phenomenas in micro levels too.

Therefore, to explain the effects this branch came with Mathematical approach.

Quantum mechanics uses

Used for the explanation of atomic and subatomic particles like electron, proton and neutron.

The theory also influenced some other theories like String and super string theory. This complicated theory is used to explain the working of Universe.

Heisenberg’s uncertainty principle comes under this, it explained that it is impossible to determine the both velocity and position of an atomic particle.

Quantum mechanics also showed that a particle can also behave as a wave. Also, many weird things explained by this branch.

Quantum Entanglement

What is Quantum mechanics

This is one of the weird nature of particles. It states that two particles connected can influence the state and behaviour of one another no matter how much the distance is.

These spooky quantum connection can be 10000 times faster than the light.

Quantum mechanics on Universe

According to quantum mechanics reality only exists when you are looking at it. Likewise the Universe doesn’t exist when there is no one born to observe it.

This is somewhat weird… Just imagine a Universe without a conscious beings. This state would be shocking. Just a Universe working without a living thing.
