Biochips

• Joseph Cullen
• BME 281

2
History

• 1980- Walter Gilbert discovered DNA sequencing
• 1983- Kary Mullis worked to detect DNA through
  lab tests
• 1986- Leroy Hood discovered florescent-based DNA
  sequencing

What is a Biochip

• Array of different chemicals and proteins
• Each in its own dot on the chip
• Used to run multiple tests simultaneously
• Dot depend on the kind of test

4
Uses

• Research
• Forensics
• Diagnosis
• Identification

5
Process

• DNA sample taken
• DNA put over chip
• cDNA and DNA on the chip match up
• The chip is then scanned
• Hooked up to a computer, which uses equations to
  determine the likeliness of the sickness

6
Benefits

• Quicker Diagnosis

7
Concerns

• Identity implants

8
Future

• Be able to find the exact diagnosis through just
  using Biochip technology
• Ability to diagnose and treat more people in
  third world countries
• Low cost tests
