Abstract

Silicon-based materials have been widely used in biological applications. However, remotely controlled and interconnect-free silicon configurations have been rarely explored, because of limited fundamental understanding of the complex physicochemical processes that occur at interfaces between silicon and biological materials. Here, we describe rational design principles, guided by biology, for establishing intracellular, intercellular and extracellular silicon-based interfaces, where the silicon and the biological targets have matched properties. We focused on light-induced processes at these interfaces, and developed a set of matrices to quantify and differentiate the capacitive, Faradaic and thermal outputs from about 30 different silicon materials in saline. We show that these interfaces are useful for the light-controlled non-genetic modulation of intracellular calcium dynamics, of cytoskeletal structures and transport, of cellular excitability, of neurotransmitter release from brain slices and of brain activity in vivo.

This work made use of the Japan Electron Optics Laboratory (JEOL) JEM-ARM200CF and JEOL JEM-3010 TEM in the Electron Microscopy Service of the Research Resources Center at the University of Illinois at Chicago (UIC). The acquisition of the UIC JEOL JEM-ARM200CF was supported by a MRI-R2 grant from the National Science Foundation (DMR-0959470). The animal imaging work conducted at the Integrated Small Animal Imaging Research Resource (iSAIRR) at the University of Chicago was supported in part by funding provided by the Virginia and D. K. Ludwig Fund for Cancer Research via the Imaging Research Institute in the Biological Sciences Division, by the University of Chicago Comprehensive Cancer Center including an NIH grant P30 CA14599, and by the Department of Radiology. Part of the schematic in Fig. 5c was generated from a three-dimensional anatomy software purchased from https://biosphera.org. The authors thank L. Yu, V. Sharapov, S. Patel, Y. Chen, Q. Guo and J.
