CMOS interface with biological molecules and cells

CMOS technology and its Moore’s Law scaling is an enormously successful technology paradigm that has continued to transform our computation and communication abilities. Outside the applications in computation and communication, CMOS technology has been increasingly applied to the life sciences, with a wealth of silicon integrated circuits developed to interface with biological molecules and cells. Concretely, large-scale arrays of active electrodes are integrated using CMOS technology for highly parallel electronic detection of biomolecular/ionic charges and cellular potentials for DNA sequencing, molecular diagnostics, and electrophysiology. Parallelism enabled by CMOS scalability is well suited to process the big data in these biotechnological applications. Here we offer a brief review on these CMOS-bio interfaces, while the corresponding presentation will focus on a sub-topic of CMOS electrophysiology with mammalian neurons.
