Abstract: Responsible commercialization of nano-enabled products (NEPs) will encompass not only the successful development of economically viable manufacturing techniques, but also, a conscious and systematic consideration of short and long-term societal impacts to avoid unintended consequences. The US National Nanotechnology Initiative has urged for more effective use of life cycle analysis (LCA) in decision-making, which in turn demands greater consideration of the ethical, legal, and social impacts (ELSI) of nanomanufacturing as it scales to commercial production. As part of its mission to establish novel directed self-assembly processes and techniques for continuous and scalable nanomanufacturing, the NSF Nanoscale Science and Engineering Center for High-rate Nanomanufacturing (CHN at Northeastern University, the University of Massachusetts Lowell and the University of New Hampshire) is developing three CNT applications that will soon move to large-scale production: electromagnetic interference (EMI) shielding, batteries, and chemical- and bio- sensors. Our current research (involving researchers from NU, UML and Yale) leverages CHN’s technical efforts by developing knowledge about life cycle impacts of CNT-enabled products – from manufacturing, through use and end-of-life. Worker safety is considered during manufacture and at product disposal in light of the uncertain hazards of CNTs. Process economics that include various levels of protection are explored. Recycled nanomaterials are explored for technical viability. Exposure assessments during end-of-life processing offer options to avoid exposures. Policy issues for responsible, sustainable development of nano-enabled products are also concurrently assessed.

Nano-scale Hyperspectral Microscopy

Title: Nano-scale Hyperspectral Microscopy

Speaker: Byron J. Cheatham, Senior VP, CytoViva, Inc.

Time: 10:00 am

Place: Room 1302

Abstract: CytoViva, Inc. provides a patented (US patents No. 7,542,203, 7,564,623) nanoscale optical microscope capability integrated with proprietary hyperspectral imaging. This integrated technology was specifically designed for optical observation, spectral characterization and mapping of nano-materials as they interact with biologicals and composite materials. The patented illumination optics of the microscope system utilizes structured oblique-angle illumination to produce a very high signal-to-noise image. Scatter from nano-scale materials imaged with CytoViva’s structured oblique-angle illumination optics can produce as much as seven times more signal intensity when compared to standard darkfield microscope optics.

Integrated hyperspectral imaging on the microscope enables capture of the unique VNIR reflectance spectra (400nm-1,000nm) of nano-scale materials within a wide range of biological and composite environments at a spectral resolution of 2.5nm. The system creates a hyperspectral image of these samples, enabling the nano-materials to be spectrally characterized and mapped throughout the entire sample.

Today over 250 nano-focused laboratories utilize CytoViva technology for nano-drug delivery, nano-toxicology and nano-materials related research initiatives. Additionally the technology is utilized in certain pathogen related studies.
