Abstract

Upconversion nanoparticle-mediated optogenetics enables remote delivery of upconverted visible light from a near-infrared light source to targeted neurons or areas, with the precision of a pulse of laser light in vivo for effective deep-tissue neuromodulation. Compared to conventional optogenetic tools, upconversion nanoparticle-based optogenetic techniques are less invasive and cause reduced inflammation with minimal levels of tissue damage. In addition to the optical stimulation, this design offers simultaneously temperature recording in proximity to the stimulated area. This chapter strives to provide life science researchers with an introduction to upconversion optogenetics, starting from the fundamental concept of photon upconversion and nanoparticle fabrication to the current state-of-the-art of surface engineering and device integration for minimally invasive neuromodulation.
