What is organic Electronics ?

• Organic electronics is a branch of electronics
  that deals with conductive/ semiconductor/
  Insulator organic materials.
• It is called 'organic' electronics because the
  molecules in the materials are carbon-based,
  like the molecules of living things.
• This is as opposed to traditional electronics
  which relies on inorganic materials such as
  copper or silicon

Buckyball (C60)
Poly(4-vinylphenol) (PVP) (Insulating Material)
Pentacene (semiconductor)
11
Why Organic Electronics

• Ultralow-cost
• Lightweight
• Devices can be fabricated on flexible substrates
• Low temperature deposition
• Large area deposition
• Organic Electronic Devices can perform
  functions traditionally accomplished using
  conventional inorganic materials

Nano Science Technology

• The creation of materials, devices and systems
  (of
• any useful size) through control/manipulation
  of matter on
• the nanometer length scale.
• Exploitation of novel properties which arise at
• the nanometer scale.
• An emerging, interdisciplinary science involving
• Physics
• Chemistry
• Biology
• Engineering
• Materials Science
• Computer Science

Development of an electronic Nose which will
be sensitive to relevant agents (chemical or
biological).
Problems with Carbon nanotubes (CNTs? - no
control over SC or metallic? - different
conductivities of NTs
Alternatives to CNTs Silicon nanowires, Zinc
Oxide nanowires - extremely pure -
Semiconductor in nature

Glucose

• A simple, large-area approach for the effective
  detection of glucose
• Work ongoing for the immobilisation of other
  bioactive molecules

17
Early detection and diagnosis of disease

• Utilise the unique properties of nanomaterials
  for the early
• diagnosis of disease.

Sense ultra-low concentrations of biological
markers at first stages of disease development.

• e.g. Alzheimers disease Present diagnostics
  detect disease
• 20-30 years after metabolic changes begin.
• Earlier therapeutic intervention, better patient
  prognosis
