三磷酸腺苷(ATP)是生物细胞维持生命活动的直接能量来源,美国哥伦比亚大学的研究团队却首次用这种生物能量来驱动芯片。他们将一个传统的固态互补金属氧化物半导体(CMOS)集成电路同一个带有ATP供电离子泵的人工脂质双层膜结合在了一起。这项发表在7日《自然通讯》网络版的最新研究为创建同时包含生物和固态组件的全新人工系统打开了大门。
Adenosine triphosphate (ATP) is a direct source of energy for biological cells to sustain life activities, but for the first time, research teams at Columbia University use this bioenergy to drive the chip. They combined a traditional solid-state complementary metal-oxide-semiconductor (CMOS) integrated circuit with an artificial lipid bilayer membrane with an ATP powered ion pump. The latest study, published online in the July 11 Nature newsletter, opens the door to creating a completely new artificial system that contains both biological and solid-state components.
