"Ultrasound triggered liposome light source for noninvasive optogenetics"

Optogenetics has revolutionized neuroscience understanding by allowing spatiotemporal control over cell-type specific neurons in neural circuits. However, visible light cannot be directly delivered to deep brain tissue, due to the severe dissipation and scattering of photons. As a result, invasive craniotomy is usually required to implant optical fibers in the brain for in vivo optogenetic stimulation, resulting in permanent damage and chronic gliosis in brain tissue. To achieve non-invasive optogenetics with high temporal resolution and excellent biocompatibility, we have developed focused ultrasound triggered nanoscopic light sources (Lipo@IR780/L012) for deep brain photon delivery. Synchronized and stable blue light emission was generated under FUS irradiation

due to the activation of chemiluminescent L012 via nearby

reactive oxygen species generated by IR780. In vitro tests

revealed that Lipo@IR780/L012 could be triggered by FUS

for light emission at different frequencies and hence

activate opsin-expressing spiking HEK cells under the FUS

irradiation. In vivo optogenetic stimulation further

demonstrated that motor cortex neurons could be

noninvasively and reversibly activated under the repetitive

FUS stimulation after i.v. injection of lipid nanoparticles to

achieve limb motions control.

"Revealing the heterogeneity in metal dissolution reaction via colocalized electrochemical and structural imaging"

Electrochemical metal dissolution reactions are fundamentally important in battery and corrosion processes. Their kinetics is highly dependent on surface structures and the presence of passive films. In this talk, I will present the study on the initiation of metal dissolution reactions on Ag and Ni, representing model systems for oxide-free and oxide-covered metals, respectively. The local dissolution kinetics is voltammetrically mapped via scanning electrochemical cell microscopy (SECCM). Co-localized characterization of crystal orientation reveals slower dissolution on {111} close-packed

planes. The local dissolution kinetics on grain boundaries

can also be directly measured, which shows a faster

dissolution rate on some but not all grain boundaries. The

dependence of passive film breakdown on the thickness of

the passive film is also revealed, which is obtained from

colocalized TOF-SIMS mapping. We demonstrate that

correlative electrochemical and structural imaging are

powerful tools for studying heterogeneity at complex

electrochemical interfaces.

Stay tuned for our Spring 2024 seminars!
