Introduction Flashcards
Biotechnology
Use of living organisms or the products of living organisms for human or animal benefit
Medical Biotechnology
Use of living cells and cell materials to produce pharmaceutical and diagnostic products that help diagnosis, treatment and prevention of disease
Biosensor
Ananlytical Device - converts biological response into a signal (commonly generated by an enzyme)
Biocatalyst
Converts substrate to product (highly specific)
Transducer
converts to electrical signal, which is amplified, processed and displayed
ELISA
colour signal, western blot
Features of biosensor
Reaction independent of stirring, pH, temp
Response should be accurate, precise, reproducible and linear
Tiny and bio-compatible if
Cheap, small, easy to use and a market for
Animal Biotechnology
used as bioreactors to produce range of therapeutic proteins
Female transgenic
Express proteins in milk - goats - silk MaSpI or MaSpII - Nexia biotech
Biosteel
compatible with human body - artificial limb, tendons and ligaments

3 examples for disease
Identify drug targets Study Cell differentiation Transplantation: bone marrow - leukaemia nerve cells - parkinsons and alzhiemers heart muscle cells - heart disease pancreatic islet cells for diabetes
