Imagine a world in which …
•cars can be assembled molecule-by-molecule
•garbage can be disassembled and turned into beef steaks,
•people can be operated on and healed by cell-sized robots
Sounds like a science fiction ?
Nanotechnology is the practical everyday application of a
futuristic science so amazing
you may have trouble believing it’s for real. But for investors,
it is very real.
semiconductor chip manufacturing encroaching upon the
ability to move individual atoms
ability to fabricate devices that can manipulate things
at the atomic level
What is Nanotechnology?
Nanotechnology, also called molecular manufacturing, is "a
branch of engineering
that deals with the design and manufacture of extremely
circuits and mechanical devices built at the molecular level of
There are many different views of precisely what is included in
1. Small size, measured in 100s of nanometers or less.
2. Unique properties because of the small size
3. Control the structure and composition on the nm scale in
order to control the properties.
Nanostructures—objects with nanometer scale features are not
new and they were not first created by man. There are many
examples of nanostructures in nature:
soot particles, etc.
We have entered the era of engineered nanomaterials and
Goals of Nanotechnology
To be able to manipulate materials at the atomic level
To build the smallest possible electromechanical devices,
given the physical limitations of matter.
In essence, the purpose of developing nanotechnology is to
have tools to work on the
molecular level analogous to the tools we have at the
Just given the basic premises of nanotechnology, you can
imagine the vast potential, such as:
o Precision Manufacturing
o Material Reuse
o Pharmaceutical Creation
o Disease Treatment
o Nanomachine-assisted Surgery
o Toxin Cleanup
o Resource Consumption Reduction

Unfortunately, the technology can be used for dangerous
o Miniature Weapons and Explosives
o Disassemblers for Military Use
• Rampant Nanomachines
o The Gray Goo Scenario
o Self Replicating Nanomachines
The flip side to these benefits is the possibility of assemblers
being used to create weapons, be used as weapons
themselves, or for them to run
wild and wreak havoc.
The ethical issues fall into the areas of equity, privacy, security,
environment, and metaphysical questions concerning human–
Privacy and security:
1.dramatically improving surveillance devices
2.producing new weapons
3.near-invisible microphones, cameras, and tracking devices
toxicity and exposure to humans and the environment

bodies or natural ecosystems

that would cause a hazard to bodies or ecosystems.

Ethical Issues & Analysis
Ethical Concepts Of Nanotechnology
Nanotechnology covers personal and social aspects of
Personal aspects covers character of individual.
Social aspects looks in harmony of society.
Nanotechnology has thrown motivists in debate since it
do not consider human emotions.
Consequentialist theory is applicable to it since its
consequence are not good.
THE INDIAN SCENARIO
There is more funding on commercial applications rather on risk
management and research and development.
Lately some initiatives have been taken for addressing risk
issues by Nano Mission and key scientific agencies.
• NIPER is developing regulatory approval guidelines for
nanotechnology based drugs and standards for toxicological
tests in nano‐based drug delivery systems.
• In 2010, DST appointed a task force which has been asked to
advice NanoMission Council to develop a regulatory body for
nanotechnology in India.
• Firms involved in nanotechnology based product
development primarily products addressing water, textile, drug
delivery have undertaken Life Cycle
Analysis (LCA) partnering with research institutes/universities.
• Standardization remains an area of concern. India, has only
taken initial first steps in addressing standardization issue.
Nano machines should not be self replicating.
A non government regulatory or advisory commision
should be setup .
Nano machines should only be specialised,not
Create institutions to monitor development of
Establish dialogue with the public and with industry.
Develop guidelines and standards for production,
handling, commercialization and risk assessment of
Nano machines should be tagged so that they can be
Ethical guidelines are needed to ensure that
nanotechnology is not used for harmful
We broaden the canves to examine regulation
towards addressing ‘responsible technology
development’, innovation governance.
