Examining the Potential of Breakthrough Nanotechnology Opportunities

National Nanomanufacturing Network - July 31, 2014 - 4:05am
Nanotechnology-enabled products offer the potential to expand future consumer markets having significant societal and economic impact. As part of its investment in nanotechnology, the U.S. government continues an open dialogue regarding the impact and return on investment of funding provided through the National Nanotechnology Initiative (NNI) to foster fundamental science, education and training, and commercialization of nanotechnology. While the NNI investment in fundamental science has clearly positioned the U.S. as the global nanotechnology leader, commercialization of nanotechnology innovations in the U.S. has lagged behind other countries such that numerous panels of advisors and committees have called for increases or shifting of funds to foster nanomanufacturing, effective technology transfer, and commercialization of these innovations. Recently, the House Subcommittee on Commerce, Manufacturing, and Trade, chaired by Rep. Lee Terry (R-NE), part of the House Committee on Energy and Commerce, held a hearing on "Nanotechnology: Understanding How Small Solutions Drive Big Innovation." Held on July 29, 2014, subcommittee members heard from several nanotech industry leaders about the current state of nanotechnology and the direction that it is headed. With Rep. Terry’s emphasis that nanotechnology brings great opportunities to advance a broad range of industries, bolster the U.S. economy, and create new manufacturing jobs, the following response excerpts by panel members heard at the hearing provide key insights into how the U.S. may capitalize from these breakthrough opportunities. Professor Milan Mrksich of Northwestern University discussed the economic opportunities of nanotechnology, and obstacles to realizing these benefits. He commented, “Current challenges to realizing the broader economic promise of the nanotechnology industry include the development of strategies to ensure the continued investment in fundamental research, to increase the fraction of these discoveries that are translated to technology companies, to have effective regulations on nanomaterials, to efficiently process and protect intellectual property to ensure that within the global landscape, the United States remains the leader in realizing the economic benefits of the nanotechnology industry.” James Phillips, Chairman CEO at NanoMech, Inc., and a member of the NanoBusiness and Commercialization Association (NanoBCA), added, “We must capitalize immediately on our great University system, our National Labs, and tremendous agencies like the National Science Foundation, to be sure this unique and best in class innovation ecosystem, is organized in a way that promotes nanotechnology, tech transfer and commercialization in dramatic and laser focused ways so that we capture the best ideas into patents quickly, that are easily transferred into our capitalistic economy so that our nation’s best ideas and inventions are never left stranded, but instead accelerated to market at the speed of innovation so that we build good jobs and improve the quality of life and security for our citizens faster and better than any other country on our planet.” Other comments by panelists emphasized the need for nanotechnology education and training, strategies for global competitiveness, benefits of public-private partnerships to accelerate the innovation ecosystem, and challenges of retaining and transitioning foreign students into the U.S. workforce. The hearing concluded with an interesting perspective presented by Chairman Terry commenting, “Nanotech is a true science race between the nations, and we should be encouraging the transition from research breakthroughs to commercial development. I believe the U.S. should excel in this area”.

Nanosensor Arrays Enable Highly Sensitive Chemical Fingerprinting for Explosive Detection

National Nanomanufacturing Network - July 31, 2014 - 3:30am
Reliable detection of trace amounts of hazardous chemicals, in particular explosives, remains a pervasive problem due to the broad variety of associated chemical compounds that must be monitored in an open environment. In combination with the inherently low vapor pressures of most explosive compounds, the challenges of detecting potential threats require sensing techniques having ultra-high sensitivity, high selectivity, and rapid response. While such performance is available using sophisticated and expensive equipment, the need exists for portable, low cost systems that can discriminate a broad range of chemical species with high sensitivity and low probability of false responses. A broad range of nanomaterials have proven effective for chem/bio detection due to their high surface to volume ratio, thereby providing high sensitivity. Effective probability of detection has been demonstrated for certain trace chemical analysis by chemically functionalizing the nanomaterial surface such that the analyte of interest has an increased affinity to bind with the nanomaterial surface, which changes the electrical properties of the sensor. While this has enabled a pathway for highly sensitive, low cost sensor platforms, chemical selectivity for detection in open environments remains a challenge. For this, the concept of a chemical nose is required that can accurately discriminate trace chemicals in air. Approaches to chemical nose sensing typically include arrays of nanosensors with different elements of the array having variable properties for binding different chemical species by varying the chemical functionality added to the individual sensors in the array. Subsequent statistical analysis of the sensor array when exposed to various compounds can then provide a specific signature associated with each compound. Establishing a library of signatures makes this approach extendable for identification of a broad range of chemical unknowns. Recently, Lichtenstein, et. al. reported on the demonstration of a chemically modified nanosensor array platform for ultrasensitive detection of explosives (http://www.nature.com/ncomms/2014/140624/ncomms5195/full/ncomms5195.html) . The reported platform consisted of 144 nanosensors arranged into 8 subarrays of 18 nanosensors. Each nanosensor element consisted of a silicon nanowire Field Effect Transistor (FET) device, with each subarray chemically modified with different small molecule receptors for ultrasensitive discrimination of chemical species. Each subarray is fed by a microfluidic channel which controls the flow and interaction of the analyte with the modified sensor array. Detection occurs by first sampling the air for 5 seconds, which is pre-concentrated by flowing through a microporous filter (50-100 l/min), then flushing the adsorbed analyte from the filter membrane using a commercially available explosive standard solution, which subsequently carries the analyte to the nanosensor subarrays. Characterization of the chemical nose platform for a range of explosive compounds demonstrated unprecedented sensitivity in the parts per quadrillion (10-15) range. More importantly, the implementation of real time mathematical analysis, kinetically and thermodynamically, of the nanosensor array elements enables discrimination and identification of numerous explosive materials with standoff distance up to several meters, including non-nitrogen containing compounds. This demonstration provides a prominent example of a nano-enabled system with unprecedented performance solving a critical problem. Further development and application of surface modification chemistries and regeneration of nanosensor surfaces will impact a much broader range of applications in chemical identification and healthcare assessment.
