What is Biotechnology?
bio the use of biological processes technolog
y to solve problems or make useful products

• Modern biotechnology the use of cellular and
  molecular processes to solve problems or make
  useful products

Emerging Areas in Biotechnology

• Biosensors
• Genomics/Bioinformatics
• Enzyme technology
• Genetic technology
• Immuno-technology

4
BIOSENSOR
- an analytical device
1. Bioreceptor
2. Physical element
Produces a signal of the recognition
Recognises a specific chemical
Transducer
Enzyme or antibody
5
How it works
Bioreceptor
Transducer
Substance recognised Gives signal
Analyte
Substance not recognised No signal given
6
Glucometer
7
Simple Biosensor
Detected by transducer
Signal and readout
Product
Blood or other fluid
Enzyme or antibody
Recognises target and reacts
8
Biosensors used in
Medicine e.g.clinical diagnosis
Industrial Process control e.g.fermentation
Environment e.g. pollution monitoring
Mining e.g.toxic gas monitoring
Pharmaceutical e.g. drug analysis
Microbiology e.g. bacteria and viral analysis
Military Application e.g. biological and
chemical warfare

Advantages of Biosensors

• Detect small amounts
• Accurate
• Easy to use
• Fast
• Cost effective
• On-line monitoring
• Continuous monitoring
