深入工程生物学的技术正变得越来越便宜,强大,并且越来越多的参与者可以使用。这一发展在为推动生物研究和生物经济提供巨大潜力的同时,也增加了无意或故意制造和传播病原体的风险。需要制定和部署有效的监管和技术框架,以管理这些新出现的生物安全和生物安保风险。在这里,我们回顾了适合应对这些挑战的一系列技术准备水平的数字和生物方法。数字序列筛选技术已经被用于控制对相关合成DNA的获取。我们研究了序列筛选,挑战和未来的发展方向,以及工程生物存在的环境监测的当前状态。作为生物体水平上的生物安全层,我们讨论了遗传生物遏制系统,可用于创建一个内在的屏障,对不受控制的环境扩散的宿主生物。生物科学;系统生物学;基因组学
Technologies to profoundly engineer biology are becoming increasingly affordable, powerful, and accessible to a widening group of actors. While offering tremendous potential to fuel biological research and the bioeconomy, this development also increases the risk of inadvertent or deliberate creation and dissemination of pathogens. Effective regulatory and technological frameworks need to be developed and deployed to manage these emerging biosafety and biosecurity risks. Here, we review digital and biological approaches of a range of technology readiness levels suited to address these challenges. Digital sequence screening technologies already are used to control access to synthetic DNA of concern. We examine the current state of the art of sequence screening, challenges and future directions, and environmental surveillance for the presence of engineered organisms. As biosafety layer on the organism level, we discuss genetic biocontainment systems that can be used to created host organisms with an intrinsic barrier against unchecked environmental proliferation.
