This document discusses nanotechnology and nanomaterials. It begins with defining nanotechnology as the study and control of matter at the nanoscale, between 1-100 nanometers. It describes how materials exhibit different properties at the nanoscale compared to larger scales. The document then covers types of nanomaterials including engineered and natural, how their properties can be tuned, and their applications across various industries like medicine, energy, and electronics. Both advantages like increased strength and disadvantages like potential health risks are addressed. The conclusion discusses the promising future of nanotechnology to revolutionize many fields.

3.  Nanotechnology is science, engineering, and
technology conducted at the nanoscale (about 1 to 100
nanometers)
 Nano can refer to technologies, materials, particles, objects –
we are focusing on nanomaterials as these are already
being used in workplaces more widely
 A sheet of paper is about 100,000 nanometers thick, a human
hair is around 80,000- 100,000 nanometers wide.
 The study of the controlling of matter on an atomic and
molecular scale ie. 1 Nanometer and involves developing or
modifying materials or devices within that size.

4. Units in nanometers (µm)

5. • Nanomaterials can :
 occur naturally
 be produced by human activity either as a product of another activity
 on purpose (engineered)

6. • At nano-scale,
 the material properties change - melting point, fluorescence,
electrical conductivity, and chemical reactivity.
 Surface size is larger so a greater amount of the material
comes into contact with surrounding materials and increases
reactivity.
• Nanomaterial properties can be ‘tuned’ by varying the size of
the particle (e.g. changing the fluorescence colour so a particle
can be identified).
• Their complexity offers a variety of functions to products .

 Smaller
 More Durable

10.  Loss of jobs (in manufacturing, farming, etc).
 Carbon Nanotubes could cause infection of lungs.
 It has very high initial investment costs along with high
manufacturing costs.
 Atomic weapons could be more accessible and
destructive.

11.  National Science and Technology Council (USA)
claims that: “Nanotechnology is an
enabling technology that will change
the nature of almost every human-made
object in the next century.”

12.  Nanotechnology helps to understand the world
around us, and will provide inspiration and
drive for many generations of scientists.
 Thus the future generation is going to continue
the fantastic voyage with Nano technology in
advanced level making life easier.
