Scalable Three-Dimensional Recording Electrodes for Probing Biological Tissues

Jung Min Lee, Dingchang Lin, Guosong Hong, Kyoung-Ho Kim, Hong-Gyu Park, Charles M. Lieber

Summary: This study demonstrates the high-performance neural recording ability of double-sided three-dimensional (3D) electrodes, which show significant improvements in neuron quantity, spike amplitude, and signal-to-noise ratio compared to standard two-dimensional electrodes. These 3D electrodes also enable stable detection of single-neuron activity over extended periods of time.

Ultrasound-activated luminescence with color tunability enabled by mechanoluminescent colloids and perovskite quantum dots

Fan Yang, Han Cui, Xiang Wu, Seong-Jong Kim, Guosong Hong

Summary: Ultrasound can deliver energy and control devices wirelessly and non-contactly, and it can propagate and focus in various mediums including biological tissue. Mechanoluminescent (ML) nanocrystal colloids activated by ultrasound provide a wireless method to remotely control a light source, such as a multicolor display. In this study, we synthesized ML colloids with bright blue emission under ultrasound using a biomineral-inspired suppressed dissolution approach, achieving small sizes down to 20 nm. By leveraging the bandgap engineering strategy of all-inorganic perovskite quantum dots (PQDs), we achieved wavelength tunability of the mechanoluminescence of ML colloid/PQD composites. The ultrasound-activated emission of the ML colloid/PQD composites exhibited a highly saturated color gamut covering the entire visible spectrum, enabling the demonstration of a flexible and wireless multicolor display with individually addressed pixels using scanning focused ultrasound.

Nanotransducer-Enabled Deep-Brain Neuromodulation with NIR-II Light

Xiang Wu, Fan Yang, Sa Cai, Kanyi Pu, Guosong Hong

Summary: The NIR-II window, ranging from 1000 to 1700 nm in wavelength, allows for deep-penetration fluorescent imaging in biological tissues due to reduced light scattering. Recently, deep-brain neuromodulation has been achieved in the NIR-II window using nanotransducers that convert NIR-II light into heat. This Perspective discusses the principles, potential applications, advantages, and limitations of this NIR-II deep-brain neuromodulation technique, as well as future directions for advancement.

Fan Yang, Seong-Jong Kim, Xiang Wu, Han Cui, Sei Kwang Hahn, Guosong Hong

Summary: Optogenetics has revolutionized neuroscience research by precisely activating specific neurons using light. However, limited penetration of visible light in neural tissue has been a challenge. Sono-optogenetics solves this problem by using ultrasound and mechano-luminescent nanotransducers for precise light production in three-dimensional neural tissue. This article provides a comprehensive review of sono-optogenetics, discussing its physical principles, emerging applications, and potential transformative impact on neuroscience research.

An optimized bioluminescent substrate for non-invasive imaging in the brain

Summary: Bioluminescence imaging (BLI) is an essential technique in biomedical research that allows non-invasive visualization of cells and biochemical events in living organisms. However, BLI in the central nervous system faces challenges due to the poor performance of luciferases and existing substrates. In this study, researchers discovered a NanoLuc substrate, cephalofurimazine (CFz), which improves the brain performance of BLI. CFz paired with Antares luciferase produces significantly higher signals in the brain compared to the standard combination of d-luciferin and firefly luciferase. This discovery enables high sensitivity imaging of the brain using NanoLuc-based indicators.

Protocol for wireless deep brain stimulation in freely behaving mice with infrared light

Xiang Wu, Guosong Hong

Summary: This article presents a protocol for deep brain stimulation in freely behaving mice using through-scalp wide-field illumination in the second near-infrared window (NIR-II). The article describes the injection of TRPV1-expressing viruses and macromolecular infrared nanotransducers for deep brain stimulation (MINDS) and details NIR-II neuromodulation in a conditioned place preference test, followed by immunohistochemical studies. This approach is particularly valuable for tether-free deep brain stimulation in social interacting experiments involving multiple subjects.

Systemically Delivered, Deep-Tissue Nanoscopic Light Sources

Xiang Wu, Fan Yang, Sa Cai, Guosong Hong

Summary: Light is widely used in life science for controlling and observing biological processes, but limited penetration depth of visible light has been a challenge for using light inside tissue. In the past decade, non-invasive deep-tissue light sources based on luminescent nanomaterials have been developed using photonics and materials science tools. This perspective provides an overview of intravital nanoscopic light sources, discussing their advantages over existing methods for in vivo light delivery, and highlighting their recent applications in optogenetics neuromodulation and fluorescent imaging in live animals. The feasibility of combining these non-invasive light sources with other modalities to expand the utilities of light in biology is also discussed.
