Weiss Group Meetings Self-Assembly & Molecular Devices Multi-Group Meetings


Tuesday 17 October 2017, 9 AM
Fudan University, Department of Macromolecular Science, Shanghai, China

Self-Assembly and Chemical Patterning across Scales
Paul S. Weiss, California NanoSystems Institute and Departments of Chemistry & Biochemistry and Materials Science & Engineering, UCLA, Los Angeles, CA 90095

We place single molecules and assemblies into precisely controlled environments on surfaces. The inserted assemblies and the monolayer matrices that contain them can be designed so as to interact directly, to give stability or other properties to functional supramolecular assemblies. New families of highly symmetric molecules are being developed to yield even greater control and are enabling elucidation of the key design parameters of both the molecules and assemblies. These design elements, in turn, enable controlled chemical patterning from the sub-nanometer to the centimeter scales. We simultaneously develop metrology tools for these methods to give unprecedented insight on the structures, function, and properties of these assemblies.


Tuesday 17 October 2017, 245 PM, Tongji University, Room 441, Decai Pavillion, Shanghai, China
Tongji University, Department of Materials Science, Shanghai, China

Precise Chemical, Physical, and Electronic Nanoscale Contacts
Paul S. Weiss, California NanoSystems Institute and Departments of Chemistry & Biochemistry and Materials Science & Engineering, UCLA, Los Angeles, CA 90095

The physical, electronic, mechanical, and chemical connections that materials make to one another and to the outside world are critical. Just as the properties and applications of conventional semiconductor devices depend on these contacts, so do nanomaterials, many nanoscale measurements, and devices of the future. We discuss the important roles that these contacts can play in preserving key transport and other properties. Initial nanoscale connections and measurements guide the path to future opportunities and challenges ahead. Band alignment and minimally disruptive connections are both targets and can be characterized in both experiment and theory. I discuss our initial forays into this area in a number of materials systems.


Wednesday 18 October 2017
Chinese Academy of Sciences, Institute of Applied Physics, Shanghai, China

Nanotechnology Approaches to Biological Heterogeneity and Cellular Therapies
Paul S. Weiss, California NanoSystems Institute and Departments of Chemistry & Biochemistry and Materials Science & Engineering, UCLA, Los Angeles, CA 90095

The great promise of single-molecule/assembly measurements is to understand how critical variations in structure, conformation, and environment relate to and control function. New approaches to sensing, imaging, and analysis are keys to elucidating these associations. I will discuss current and upcoming advances and will pose the challenges that lie ahead in creating, developing, and applying new tools for biology and medicine. These advances include using biomolecular recognition in sensor arrays to probe dynamic chemistry in the brain and microbiome systems. It also includes fusing spectroscopic imaging modalities and freeing up bandwidth in measurements to record simultaneous data streams and to expand our dynamic range. Recent advances in sparsity and compressive sensing can be applied both to new analysis methods and to directing measurements so as to assemble and to converge structural and functional information. Early examples will be discussed.

Beijing University of Chemical Technology, Beijing, China

Global Opportunities in Nanoscience and Nanotechnology
Paul S. Weiss, California NanoSystems Institute and Departments of Chemistry & Biochemistry and Materials Science & Engineering, UCLA, Los Angeles, CA 90095

Two seemingly conflicting trends in nanoscience and nanotechnology are our increasing ability to reach the limits of atomically precise structures and our growing understanding of the importance of heterogeneity in the structure and function of molecules and nanoscale assemblies. By having developed the "eyes" to see, to record spectra, and to measure function at the nanoscale, we have been able to fabricate structures with precision as well as to understand the important and intrinsic heterogeneity of function found in these assemblies.

I will discuss the challenges, opportunities, and consequences of pursuing strategies to address both precision on the one hand and heterogeneity on the other. In our laboratories, we are taking the first steps to exploit precise assembly to optimize properties such as perfect electronic contacts in materials. We are also developing the means to make tens to hundreds of thousands of independent multimodal nanoscale measurements in order to understand the variations in structure and function that have previously been inaccessible in both synthetic and biological systems.

Another outcome of the development of our field has been our ability to communicate across fields. This skill that we develop in our students and colleagues has enhanced and accelerated the impact of nanoscience and nanotechnology on other fields, such as neuroscience and the microbiome. I will discuss the opportunities presented by these entanglements and give recent examples of advances enabled by nanoscience and nanotechnology.

Understanding Energy Conversion at the Ultimate Limits of Miniaturization
Paul S. Weiss, California NanoSystems Institute and Departments of Chemistry & Biochemistry and Materials Science & Engineering, UCLA, Los Angeles, CA 90095

I will discuss the challenges, opportunities, and consequences of pursuing strategies to address both precision on the one hand and heterogeneity on the other [1]. In our laboratories, we are taking the first steps to exploit precise assembly to optimize properties such as perfect electronic contacts in materials [2]. We are also developing the means to make tens to hundreds of thousands of independent multimodal nanoscale measurements in order to understand the variations in structure and function that have previously been inaccessible in both synthetic and biological systems [3,4].

Nanotechnology Approaches to Cellular Therapies
Paul S. Weiss1,2,3
1California NanoSystems Institute and Departments of 2Chemistry & Biochemistry and 3Materials Science & Engineering, UCLA, Los Angeles, CA 90095

We introduce biomolecular payloads into cells for gene editing at high throughput for off-the-shelf solutions targeting hemoglobinopathies, immune diseases, and cancers. We circumvent the need for viral transfection and electroporation, both of which have significant disadvantages in safety, throughput, cell viability, and cost. Mechanical deformation can make cell membranes transiently porous and enable gene-editing payloads to enter cells. These methods use specific chemical functionalization and control of surface contact and adhesion in microfluidic channels. Likewise, penetration of reproducibly nanomanufactured, loaded sharp features can introduce these packages into individual or many cells. We discuss our progress with these approaches and the methods that we use to quantify success.
