Speech title: Semiconductor Nanowires for Optoelectronics Applications
Abstract: Semiconductor Nanowires are considered as building blocks for the next generation electronics and photonics. In this talk, I will review our recent results semiconductor nanowires and nanomembranes for discuss about their optical and electronic properties. I will discuss control of crystal phases and associated changes in optical properties. I will present results on nanowire lasers, nanowire THz photodetectors and polarizers, use of nanowires for energy and neuroscience applications. I will also discuss about the future prospects of nanowires.
President of Hainan University, China
Qingming Luo is an elected Fellow of AIMBE, SPIE, OSA, IET and COS. He has been devoted to new techniques and novel applications in life sciences, including laser speckle imaging (LSI) and combination with optical intrinsic signal imaging (ISI), small animal imaging of fluorescence diffusion optical tomography (fDOT) coregistered with micro-CT, micro-optical sectioning tomography (MOST), and functional near infrared (NIR) imaging. He created “the most detailed three-dimensional map of all the connections between the neurons in a complete mouse brain” and “demonstrated the first long-range tracing of individual axons in the mouse brain” with BPS.
Speech title: Brain-wide Positioning System for Brainsmatics
Abstract: Deciphering the fine morphology and precisely positioning the neurons and neural circuits are crucial to enhance our understanding of brain function and diseases. Traditionally, we have to map brain images to coarse axial-sampling planar reference atlases to orient neural structures, which might fail to orient neural projections at single-cell resolution due to position errors resulting from individual differences at the cellular level. In last one and half decade, my lab developed a Micro-Optical Sectioning Tomography (MOST) and several types of fluorescence MOST (fMOST), which is a novel combination of the microscopic optical imaging and the physical sectioning to obtain the tomographic information of a whole brain with sub-micron voxel resolution. In the first part of my talk, I will introduce the principles of Brain-wide Positioning Systems (BPS) which refers to MOST/fMOST serial techniques. In the second part of my talk, I will demonstrate how to brain-widely position the labelled neurons and neuronal networks, including whole-brain samples preparing, whole-brain optical imaging as well as massive brain-image processing and analyzing. The unique features of BPS include 1) robust absorption/fluorescence imaging, 2) multi-color imaging, 3) submicron voxel resolution for a single cm-size whole mouse brain, 4) automatic in sectioning, imaging and data acquisition, 5) no registration needed for 3-D imaging, 6) extensible for 3-D large scale imaging, potentially to 10´10´10 cm3. Based on BPS, we have acquired the first 3D structure atlas of whole mouse brain at single-neuron resolution; achieved tracing axonal pathways in the mouse brain without interruption for the first time; first dissected neural structures with anatomical annotation at single-neuron resolution; revealed the mechanism of fluorescent signal change in resin-embedded sample; realized the automatic tracing and reconstruction of neuronal populations with dense dendrites. We propose a new term: BRAINSMATICS, which refers to the integrated, systematic approach of measuring, analyzing, managing and displaying brain spatial data with unprecedented single-neuron resolution. The serial BPS have the advantages of high resolution, high throughput and long-time stability. With the brain-spatial information of neuron types, neural circuits, vascular networks and 3D fine brain atlas, we believe that brainsmatics makes it possible to better decipher genetically defined cell types and connectome.
