Harnessing the potential of optogenetics in biology requires methodologies from different disciplines and suitable light stimulation platforms. This review explores the evolution of light-induction hardware-software platforms, discusses their advantages and disadvantages, and examines design approaches in optogenetic experiments. The development of automated measurement and stimulation schemes on these platforms enables computer-controlled living systems.
Harnessing the potential of optogenetics in biology requires methodologies from different disciplines ranging from biology, to mechatronics engineering, to control engineering. Light stimulation of a synthetic optogenetic construct in a given biological species can only be achieved via a suitable light stimulation platform. Emerging optogenetic applications entail a consistent, reproducible, and regulated delivery of light adapted to the application requirement. In this review, we explore the evolution of light-induction hardware-software platforms from simple illumination set-ups to sophisticated microscopy, microtiter plate and bioreactor designs, and discuss their respective advantages and disadvantages. Here, we examine design approaches followed in performing optogenetic experiments spanning different cell types and culture volumes, with induction capabilities ranging from single cell stimulation to entire cell culture illumination. The development of automated measurement and stimulation schemes on these platforms has enabled researchers to implement various in silico feedback control strategies to achieve computer-controlled living systems-a theme we briefly discuss in the last part of this review.
