The design of in vivo computers is more complex than in vitro computers, not only because the insufficiency of knowledge in cellular environment and self-control mechanism, but also the unknowing impact on life if computing is embedded inside.

• 体内计算机的设计远比体外计算机要复杂，这不仅因为对生物体的体内环境知识的匮乏和对生物自身调控机制的不甚了解，而且也是对将计算植入生物体内所造成的对生物体的影响估计不足。
