Synthetic biology is an emerging scientific field that combines engineering and biology to design and construct novel biological systems or redesign existing natural biological systems. The document provides a brief history of synthetic biology from 1960 to 2013, highlighting key developments such as the first synthetic genetic circuits in 2000-2003 and the engineering of metabolic pathways. It also discusses topics such as standard biological parts, modeling and design techniques, applications in health, energy and environment, as well as potential risks that need consideration with the further development of the field.

described as the design and construction of
novel artificial biological pathways,
organisms or devices, or the redesign of
existing natural biological systems.

synthetic biology redefines life
broadly the term has been used
with reference to effort to
redesign life.
this use of the term is an
extension of the concept of
biomimetic chemistry in which
organic synthetic is used to creat
artifical molecules .typically
enzymes

- is the study of systems of biological
components, which may be molecules,
cells, organisms or entire species.
The systems biology approach allows
the study of multi-scale, multi-level
organisms.
Systems biology involves :
(1) collection of large sets of experimental data
(2) proposal of mathematical models
(3) accurate computer solution of the mathematical equations to
obtain numerical predictions
(4) assessment of the quality of the model by comparing numerical
simulations with the experimental data.

Systems biology aims to study
natural biological systems as a
whole, often with a biomedical
focus, and uses simulation and
modelling tools in comparisons
with experimental information.
Synthetic biology aims to build
novel and artificial biological
parts, devices and systems.

Building a system from standard parts

15. 15
A biopart is a modular biological part
which is designed so that
it can be easily combined with other
parts. Ultimately, the aim is to produce
a range of standard devices which can
be used in standard systems.
The biopart standard provides a
framework where parts can be re-
used in various applications to
achieve the specific function
intended for the device.

Central to the understanding of international
standards is the concept of the biological continuum,
ie the hierarchy of the human organism comprising:

What is SBOL? SBML-the Systems Biology Markup Languageis a
standard for behavioral models of biological
systems at the molecular level
SBOL-the Synthetic Biology Open Language
describes structural and basic qualitative
behavioral aspects of a biological design.
approach of SBOL:
• Facilitates storage of genetic designs in repositories
• Helps synthetic biologists and genetic engineers electronically
exchange designs with each other and with biofabrication centers
• Supports development of Genetic Design Automation (GDA)
software tools for synthetic biologists
• Represents hierarchically assembled genetic compositions
• Represents abstract genetic compositions without an explicit
nucleotide sequence
• Allows expression of genetic designs in publications and thus

Applications of synthetic biology
The ultimate goal of synthetic biology is to develop commercial
applications that will benefit society, ie to design and build
engineered biological systems that process information, manipulate
chemicals, fabricate materials and structures, produce energy,
provide food, and maintain and enhance human health and our
environment.
