Technology 3Heartsbreath Breathalyzers

• A breath sensor, a billion times more
  sensitive than police breathalyzers, can already
  check for asthma, ulcers or trouble with a heart
  transplant, and if the chemical fingerprint of a
  disease is known, it can test for it. Crucial to
  the test is not the shallow breath from the upper
  part of our lungs but the breath derived from
  alveoli, the tiny chambers at the tips of the
  bronchial air passages, deep inside. Alveoli are
  lined with membranes loaded with tiny blood
  vessels. The chemicals in the blood easily cross
  this membrane so that the alveolar breath
  "mirrors the composition of the blood."

Technology3Heartsbreathalyzers Opportunity

• In the future, hand-held devices similar to a
  Palm Pilot may be routinely used for the early
  detection of breast, colon and other cancers,
  tuberculosis, diabetes and pre-eclampsia.
• Home monitoring hand-held breath monitors will
  on day be used at home to check our health and
  the evolution of our diseases.
• Increase testing for disease/health conditions

Technology 3Heartsbreathalyzer Benefits

• Early detection of diseases and conditions.
• Reduction in costs of testing
• Innovative and less invasive test for diseases
  and health conditions.
• Reduction in the cost of traditional tests for
  diseases and health conditions
• At home patient monitoring of progression of
  disease and present condition.

Technology 2Dynamic 3D echocardiographyin
virtual reality

• Doctors are using a virtual reality system to
  visualize the heart in three dimensions and
  detect if it is healthy or not. In a pilot
  study, ten doctors were able to move around
  virtual three-dimensional animated images or
  'holograms' of the heart and to make correct
  diagnosis after a ten-minute training.

pair of glasses with polarizing lenses. Within
the I-space the head and hand movements of the
viewer is being tracking by four infrared
cameras, allowing a natural interaction with the
images that are displayed.

Technology 2Dynamic 3D echocardiographyin
virtual reality - Opportunities

• Until now, the 3D echocardiographic
  reconstructions could only be seen on a 2D
  screen, but virtual reality makes it possible to
  'dive' into the actual 3D anatomy of the heart.
• Professionals, familiar with intracardiac
  anatomy, can learn how to handle the technique
  and cut through these holograms within 10
  minutes.
• Subsequently, they were all able to correctly
  diagnose the intracardiac anatomy or pathology of
  the mitral valve.
• At the moment, I-Space technology is only
  available in a few dedicated research centres
  throughout the world. Therefore, the combination
  of the 3D echocardiography and virtual reality is
  very uncommon and the applicability and
  usefulness in clinical practice is still limited.

Technology 1Nanocarriers to Fight Cancer

• Anticancer drugs are now being administered to
  patients using methods that cause the
  indiscriminate killing of both diseased and
  healthy cells.
• Such chemotherapy leads to side-effects, such as
  nausea, fatigue, and hair loss, and makes the
  patient weak and frail.
• For these reasons, there is a crucial need for
  the development of more effective cancer therapy,
  which not only minimizes side-effects but also
  directly targets diseased cells.

17
Technology 1Nanocarriers to Fight Cancer

• Researchers at the Institute of Bioengineering
  and Nanotechnology (IBN) in Singapore have
  designed 'smart' nanocarriers which deliver the
  drugs exactly where they are needed, reducing
  side effects and suppressing cancer growth. Their
  core-shell nanoparticles are both sensitive to
  temperature and to acidic levels. When these
  nanocarriers encounter acidic environments such
  as tumor tissues, they break apart and release
  the molecules they contain.

Technology 1 - OpportunityNanocarriers to Fight
Cancer

• Intelligent drug delivery.
• Opportunity for a more effective cancer therapy -
  Directly targets diseased cells.
• Minimizes side-effects of current radiation
  treatments.
• This technology may also be used in in-vitro and
  animal studies for drug discovery.

Technology 1 - BenefitsNanocarriers to Fight
Cancer

• Intelligent drug delivery
• Quality of life patient and family
• Reduction in the risk to healthcare
  professionals.
• The powerful drugs used in chemotherapy can
  themselves cause cancer and pose a risk to
  nurses, pharmacists and others who handle them.
• Significant reduction in healthcare costs.
