Abstract: Abstract: Synthetic biology is an emerging field of biological research that combines science and engineering to study the mechanism of life and for a variety of technological applications. Research in synthetic biology has primarily focused on developing an engineering dogma for bottom-up design and synthesis of biological circuits from standardized parts and modules followed by optimizing their operation on well-characterized chassis， in vivo or in vitro. Recent progress in synthetic biology， such as significant improvements in efficient DNA/gene synthesis and ever increasing knowledge of biological systems via genomic and functional genomic analysis enables scientists to design and construct increasingly complex genetic devices and circuits， to synthesize and assembly bacterial genomes， and to develop artificially modified biological systems to produce renewable chemicals， biofuels， pharmaceutical intermediates， health care products and new tools for environment protection. However， neither the scientific complexity nor the technological uncertainty of the research has been thoroughly studied. In addition， the legal and ethical concerns of its social and humanitarian impact is largely yet to be addressed. Proper regulations should be developed to support the innovation and related application transformation while protecting the public from potential harms.
