Energy and charge transport play fundamental roles in both electronic devices and biological systems, and recent advances in our understanding show surprising parallels between what is needed for a molecular electronic technology and understanding key aspects of living systems. In particular, exciting advances have been made in the understanding of transport mechanisms within disordered media. Disorder can create trapping sites for electrons that in turn prevent stable operation of devices such as transistors. However, disorder can also switch conduction on and off through an Anderson transition that may play a role both in transistors and proteins.

能量和电荷传输在电子设备和生物系统中发挥着重要作用，我们对分子电子技术的理解与对生命系统关键方面的理解之间有着惊人的相似之处。特别是，在无序介质中的传输机制的理解方面取得了令人兴奋的进展。无序可以产生电子的捕获位置，这反过来又会阻止诸如晶体管之类的器件的稳定操作。然而，无序也可以通过安德森转变来开关传导，这种转变可能在晶体管和蛋白质中都起作用。
