This document presents information about nanotechnology from a seminar given by Ayush Verma. It defines nanotechnology as building things on the scale of atoms and molecules, and discusses its applications in energy (e.g. more efficient solar panels), biomedical (e.g. disease diagnosis and treatment), food (e.g. food safety sensors), and textiles (e.g. smart fabrics). The advantages include cleaner water and air through nanotechnology solutions, while disadvantages include high energy requirements and potential environmental harm from toxic nanoparticles. The future of nanotechnology is seen as having both opportunities and risks that require involvement from scientists, governments, and the public.

3. NANOTECHNOLOGY-
Nanotechnology is a field of research and innovation
concerned with building things generally materials
and devices on the scale of atoms and molecules.
Nanotechnology can increase the efficiency of energy
consumption, help clean the environment and solve
major health problems.
Products of nanotechnology will be smaller, cheaper,
lighter yet more functional and require less energy
and fewer raw material to manufacture.

4. APPLICATIONS OF NANOTECHNOLOGY-
1.ENERGY-
A new semiconductor developed by Kyoto University makes it
possible to manufacture solar panels that double the amount of
sunlight converted into electricity. Nanotechnology also lowers
costs, produces stronger and lighter wind turbines, improves fuel
efficiency and thanks to the thermal insulation of some
nanocomponents can save energy.
2.BIOMEDICINE-
The properties of some nanomaterials make them ideal for
improving early diagnosis and treatment of
neurodegenerative diseases or cancer.

3.FOOD-
In this field ,Nano biosensors could be used to detect the presence
of pathogens in food or nanocomposites to improve food
production by increasing mechanical and thermal resistance and
decreasing oxygen transfer in packaged products.
4.TEXTILES-
Nanotechnology makes it possible to develop smart fabrics that
don’t stain nor wrinkle as well as stronger, lighter and more durable
materials to make motorcycle helmets or sports equipment.

6. ADVANTAGE-
1.Water Cleanliness- Nanotechnology based solutions can
contribute to the long term quality availability, and viability of
water in several ways.
2.Cleansing The Air- Current methods to separate CO2 from
waste gases are expensive.
3.Save The Seas- Oil spills can be catastrophic for oceans,
rivers, and the wildlife that reside within it.

7. DISADVANTAGES-
1. High energy requirements for synthesizing
nanoparticles causing high energy demand.
2. Dissemination of toxic, persistent nanosubstance's
originating environmental harm.
3. Lower recovery and recycling rates.

8. NANOTECHNOLGY IN THE FUTURE-
There are bright and dark spots in the future of
nanotechnology.
Assessing the role of nanotechnology and guiding its
progression will require cross sector involvement of
scientists, governments, civil society organizations and
the general public.
