The document discusses nanotechnology and its applications. It begins by explaining how nanotechnology works by manipulating individual atoms and arranging them into desired structures using building blocks smaller than 100 nanometers. It then provides examples of nanotechnology applications in medicine such as more effective drugs, nanobots for targeted drug delivery, and diagnosing diseases. Nanotechnology is also used for water purification with nanoparticle filters and self-cleaning surfaces. Additional applications discussed include agriculture using nanoparticles to detect pests and enhance crop nutrients, as well as using nanomaterials for renewable energy and more efficient chemical processes. The document concludes by mentioning some ethical challenges from widespread nanotechnology use such as potential environmental contamination and threats to privacy.

WORKS?

13. HOW NANOTECHNOLOGY WORKS?
• Atoms are the Building
blocks for all matter in
our universe
• Atoms are molecules that
stick together
• Every atom has a
exhibits different
property at various
conditions
• The goal of
nanotechnology is to
manipulate atoms
individually and place
them in a pattern to
produce a desired
structure.
• Atoms are the Building
blocks for all matter in
our universe

14. Application: MEDICINE & WATER PURIFICATION
Field of Medicine
Development of more effective drugs.
Nanobots – molecular-scale workers that
can employ molecular processes within
cells, which can deliver drugs to specific
molecular sites.
Biological mechanisms can be stimulated to
destroy cancer cell while it is treated by
drug-bearing nanoparticles.
Possible to diagnose prevalent contagious
diseases such as HIV/AIDS, malaria,
tuberculosis.

16. Application: MEDICINE & WATER PURIFICATION
Water Purification System
• Containing nanomaterials and
utilizing new membrane technologies
variable fore-sized filters.
Nanoparticles
• Used to prepare heat-resistant and
self-cleaning surfaces like floor and
benchtops.
• Nanoparticles of silicon dioxide or
titanium dioxide can also make surface repel
water.

17. question
Screening devices using nanotechnology can diagnose
prevalent contagious diseases except:
a. HIV/AIDS
b. Cancer
c. Tuberculosis
d. malaria

18. Application: AGRICULTURE
• The use of TiO2 nanoparticles.
• Chlorinated compounds (i.e.,
chlorinated solvents and pesticides,
polychlorinated biphenyls (PCB), and
brominated compounds)
• Silver (Ag)
• Novel techniques of nanotechnology
applications are applied breed crops with
higher levels of micronutrients to detect pests
and to control food processing.

19. Application: bionanotechnology
• Nanotechnology helps in energy
consumption like in the use of graphene into
a coating material resulting in the need for
only one layer, which does not require a
multifunctional film coating.
• Bionanotechnology can support cleaner
production methods and provide alternative
and renewable energy sources to enhance the
sustainability of factories.
• Nanoscale chemical reagents or
catalysts are smaller yet they increase the
rate of chemical reactions, thus lessening the
input of raw materials.

20. question
a simple, cheap, and effective way of removing arsenic soil
and water is through the use of _______.
a. Titanium Dioxide Nanoparticles
b. Metal Nanoparticles
c. Aluminium Oxide
d. Carbon Nanotubes

24. Ethical Issues & Analysis
• Potential dangers • Formulating solution
We must examine the ethics of developing nanotechnology
and create policies that will aid in its development so as to
eliminate or at least minimize its damaging effects on
society.

25. Other Ethical Issues prior to Nanotechnology
• Nanotechnology will give us more "god-like" powers
• It has to potential to eliminate other ethical issues (e.g. assembling
beef instead of slaughtering cows, constructing cells rather than
getting them from reproduction, etc...)
• May lead to undetectable surveillance, Right to Privacy could be
jeopardized
• Do we have a duty to help and provide for others [countries] with
this technology?
