More information about biosafety

We encourage you to do this kind of research as part of your bibliography for whatever project you are working on.

  • Here is the link to an openwetware page that should be improved by the community. This report exists to improve biosafety practices in synthetic biology, raise good questions, and encourage collaboration in exploring the issue.

Recommendation from Human Practice Teams

  • Report of Sara Aguiton : [http://2009.igem.org/Team:Paris/Ethics_ethicalreport#top report]
  • Report of Claire Mayer : [http://2012.igem.org/Team:Paris_Bettencourt/Human_Practice/Report report]

Conclusion of these reports :

  • daily and local efforts : An ethical reflection on practices, discourses and social interactions.
  • A responsible position regarding what scientific paradigms, through concepts, perceptions and values, are emerging with this field.
  • The need to raise awareness of synthetic biology in the population so people can decide in the most enlightened way possible if they want of this new technology and its applications.
  • The need of a discussion between society’s different decision makers to set goals and a definition of what they would consider benefits and acceptable risks.

  • The need for an INDEPENDENT cohort of scientists to test experimentally any application of synthetic biology that requires release into the environment.

Proposals to improve this page (Feel free to add ideas)

  1. Add a biosafety grade, that could quantify the degree of robustness. For instance, in semantic containment with amber mutation, we score the robustness with the number of amber mutations.

Example of biosafety systems

Here are reported biosafety systems that teams created. The risk and hazards of these systems are assessed through fault tree analysis, a top-down approach used in engineering field.

Semantic Containment

Here are parts that would add a semantic containment to genes, or parts that would allow the cell to read semantic containments gene.
