1.
The discovery of vitamins
Vitamins are organic compounds that are needed in the
human body in very small amounts, usually less than 0.01 grams per day.
Although only needed in small amounts, but vitamins are very important
compounds (vital) for the human body meaning that if these vitamins are not
present in the body, then the health of the body will be disrupted. These
vitamins are only obtained from outside the body, because the human body cannot
produce vitamins. With the discovery of these vitamins, it can be used by
humans to maintain health through the composition of a healthy and balanced
diet.
2.
The discovery of penicillin antibiotics
At the beginning of 1942, British scientist Alexander
Fleming reported that a substance produced by the fungus Penicilium notatum
which was named penicillin had the ability to kill bacteria that cause disease.
Fleming watched a set of old petri dishes which he had left behind. He
discovered that the Staphylococcus aureus colony he had scratched on the petri
dish had been destroyed. Destruction of bacterial cells occurs in areas
adjacent to pollutant fungi that grow on petri dishes. He suspected that a
product of the fungus caused the destruction of staphylococcal cells. The
product was later named penicillin because the pollutant fungus was identified
as Penicillium
notatum.
3. Vaccine discovery
The first vaccine was discovered by Edward Jenner.
Currently, vaccines continue to be developed and refined with the application
of biotechnology such as recombinant vaccine produced so that it is more pure
and potential.
4.
The discovery of monoclonal antibodies
Monoclonal antibodies can be produced by techno
biological methods. Monoclonal antibodies have advantages including: very
sensitive, characteristic (specificity), and accurate. The contribution of
monoclonal antibodies has been felt its benefits, especially in research in the
field of health. Similarly, the use of monoclonal antibodies is increasingly
widespread both for clinical trials including diagnosis and treatment to
achieve specific cell targets.
5.
Genetically modified insulin production
The hormone insulin can be mass produced by applying
genetic engineering methods by inserting certain genes that are desired into
cells that have been cultured.
